What Is a Case Study? | Definition, Examples & Methods

Published on May 8, 2019 by Shona McCombes . Revised on November 20, 2023.

A case study is a detailed study of a specific subject, such as a person, group, place, event, organization, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.

A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating and understanding different aspects of a research problem .

Table of contents

When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyze the case, other interesting articles.

A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.

Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.

You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.

Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:

• Provide new or unexpected insights into the subject
• Challenge or complicate existing assumptions and theories
• Propose practical courses of action to resolve a problem
• Open up new directions for future research

TipIf your research is more practical in nature and aims to simultaneously investigate an issue as you solve it, consider conducting action research instead.

Unlike quantitative or experimental research , a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.

Example of an outlying case studyIn the 1960s the town of Roseto, Pennsylvania was discovered to have extremely low rates of heart disease compared to the US average. It became an important case study for understanding previously neglected causes of heart disease.

However, you can also choose a more common or representative case to exemplify a particular category, experience or phenomenon.

Example of a representative case studyIn the 1920s, two sociologists used Muncie, Indiana as a case study of a typical American city that supposedly exemplified the changing culture of the US at the time.

While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:

• Exemplify a theory by showing how it explains the case under investigation
• Expand on a theory by uncovering new concepts and ideas that need to be incorporated
• Challenge a theory by exploring an outlier case that doesn’t fit with established assumptions

To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.

There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews , observations , and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data.

Example of a mixed methods case studyFor a case study of a wind farm development in a rural area, you could collect quantitative data on employment rates and business revenue, collect qualitative data on local people’s perceptions and experiences, and analyze local and national media coverage of the development.

The aim is to gain as thorough an understanding as possible of the case and its context.

In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.

How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis , with separate sections or chapters for the methods , results and discussion .

Others are written in a more narrative style, aiming to explore the case from various angles and analyze its meanings and implications (for example, by using textual analysis or discourse analysis ).

In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.

Case studies

Case studies are essential to qualitative research , offering a lens through which researchers can investigate complex phenomena within their real-life contexts. This chapter explores the concept, purpose, applications, examples, and types of case studies and provides guidance on how to conduct case study research effectively.

Whereas quantitative methods look at phenomena at scale, case study research looks at a concept or phenomenon in considerable detail. While analyzing a single case can help understand one perspective regarding the object of research inquiry, analyzing multiple cases can help obtain a more holistic sense of the topic or issue. Let's provide a basic definition of a case study, then explore its characteristics and role in the qualitative research process.

Definition of a case study

A case study in qualitative research is a strategy of inquiry that involves an in-depth investigation of a phenomenon within its real-world context. It provides researchers with the opportunity to acquire an in-depth understanding of intricate details that might not be as apparent or accessible through other methods of research. The specific case or cases being studied can be a single person, group, or organization – demarcating what constitutes a relevant case worth studying depends on the researcher and their research question .

Among qualitative research methods , a case study relies on multiple sources of evidence, such as documents, artifacts, interviews , or observations , to present a complete and nuanced understanding of the phenomenon under investigation. The objective is to illuminate the readers' understanding of the phenomenon beyond its abstract statistical or theoretical explanations.

Characteristics of case studies

Case studies typically possess a number of distinct characteristics that set them apart from other research methods. These characteristics include a focus on holistic description and explanation, flexibility in the design and data collection methods, reliance on multiple sources of evidence, and emphasis on the context in which the phenomenon occurs.

Furthermore, case studies can often involve a longitudinal examination of the case, meaning they study the case over a period of time. These characteristics allow case studies to yield comprehensive, in-depth, and richly contextualized insights about the phenomenon of interest.

The role of case studies in research

Case studies hold a unique position in the broader landscape of research methods aimed at theory development. They are instrumental when the primary research interest is to gain an intensive, detailed understanding of a phenomenon in its real-life context.

In addition, case studies can serve different purposes within research - they can be used for exploratory, descriptive, or explanatory purposes, depending on the research question and objectives. This flexibility and depth make case studies a valuable tool in the toolkit of qualitative researchers.

Remember, a well-conducted case study can offer a rich, insightful contribution to both academic and practical knowledge through theory development or theory verification, thus enhancing our understanding of complex phenomena in their real-world contexts.

What is the purpose of a case study?

Case study research aims for a more comprehensive understanding of phenomena, requiring various research methods to gather information for qualitative analysis . Ultimately, a case study can allow the researcher to gain insight into a particular object of inquiry and develop a theoretical framework relevant to the research inquiry.

Why use case studies in qualitative research?

Using case studies as a research strategy depends mainly on the nature of the research question and the researcher's access to the data.

Conducting case study research provides a level of detail and contextual richness that other research methods might not offer. They are beneficial when there's a need to understand complex social phenomena within their natural contexts.

The explanatory, exploratory, and descriptive roles of case studies

Case studies can take on various roles depending on the research objectives. They can be exploratory when the research aims to discover new phenomena or define new research questions; they are descriptive when the objective is to depict a phenomenon within its context in a detailed manner; and they can be explanatory if the goal is to understand specific relationships within the studied context. Thus, the versatility of case studies allows researchers to approach their topic from different angles, offering multiple ways to uncover and interpret the data .

The impact of case studies on knowledge development

Case studies play a significant role in knowledge development across various disciplines. Analysis of cases provides an avenue for researchers to explore phenomena within their context based on the collected data.

This can result in the production of rich, practical insights that can be instrumental in both theory-building and practice. Case studies allow researchers to delve into the intricacies and complexities of real-life situations, uncovering insights that might otherwise remain hidden.

Types of case studies

In qualitative research , a case study is not a one-size-fits-all approach. Depending on the nature of the research question and the specific objectives of the study, researchers might choose to use different types of case studies. These types differ in their focus, methodology, and the level of detail they provide about the phenomenon under investigation.

Understanding these types is crucial for selecting the most appropriate approach for your research project and effectively achieving your research goals. Let's briefly look at the main types of case studies.

Exploratory case studies

Exploratory case studies are typically conducted to develop a theory or framework around an understudied phenomenon. They can also serve as a precursor to a larger-scale research project. Exploratory case studies are useful when a researcher wants to identify the key issues or questions which can spur more extensive study or be used to develop propositions for further research. These case studies are characterized by flexibility, allowing researchers to explore various aspects of a phenomenon as they emerge, which can also form the foundation for subsequent studies.

Descriptive case studies

Descriptive case studies aim to provide a complete and accurate representation of a phenomenon or event within its context. These case studies are often based on an established theoretical framework, which guides how data is collected and analyzed. The researcher is concerned with describing the phenomenon in detail, as it occurs naturally, without trying to influence or manipulate it.

Explanatory case studies

Explanatory case studies are focused on explanation - they seek to clarify how or why certain phenomena occur. Often used in complex, real-life situations, they can be particularly valuable in clarifying causal relationships among concepts and understanding the interplay between different factors within a specific context.

Intrinsic, instrumental, and collective case studies

These three categories of case studies focus on the nature and purpose of the study. An intrinsic case study is conducted when a researcher has an inherent interest in the case itself. Instrumental case studies are employed when the case is used to provide insight into a particular issue or phenomenon. A collective case study, on the other hand, involves studying multiple cases simultaneously to investigate some general phenomena.

Each type of case study serves a different purpose and has its own strengths and challenges. The selection of the type should be guided by the research question and objectives, as well as the context and constraints of the research.

The flexibility, depth, and contextual richness offered by case studies make this approach an excellent research method for various fields of study. They enable researchers to investigate real-world phenomena within their specific contexts, capturing nuances that other research methods might miss. Across numerous fields, case studies provide valuable insights into complex issues.

Critical information systems research

Case studies provide a detailed understanding of the role and impact of information systems in different contexts. They offer a platform to explore how information systems are designed, implemented, and used and how they interact with various social, economic, and political factors. Case studies in this field often focus on examining the intricate relationship between technology, organizational processes, and user behavior, helping to uncover insights that can inform better system design and implementation.

Health research

Health research is another field where case studies are highly valuable. They offer a way to explore patient experiences, healthcare delivery processes, and the impact of various interventions in a real-world context.

Case studies can provide a deep understanding of a patient's journey, giving insights into the intricacies of disease progression, treatment effects, and the psychosocial aspects of health and illness.

Asthma research studies

Specifically within medical research, studies on asthma often employ case studies to explore the individual and environmental factors that influence asthma development, management, and outcomes. A case study can provide rich, detailed data about individual patients' experiences, from the triggers and symptoms they experience to the effectiveness of various management strategies. This can be crucial for developing patient-centered asthma care approaches.

Other fields

Apart from the fields mentioned, case studies are also extensively used in business and management research, education research, and political sciences, among many others. They provide an opportunity to delve into the intricacies of real-world situations, allowing for a comprehensive understanding of various phenomena.

Case studies, with their depth and contextual focus, offer unique insights across these varied fields. They allow researchers to illuminate the complexities of real-life situations, contributing to both theory and practice.

Understanding the key elements of case study design is crucial for conducting rigorous and impactful case study research. A well-structured design guides the researcher through the process, ensuring that the study is methodologically sound and its findings are reliable and valid. The main elements of case study design include the research question , propositions, units of analysis, and the logic linking the data to the propositions.

The research question is the foundation of any research study. A good research question guides the direction of the study and informs the selection of the case, the methods of collecting data, and the analysis techniques. A well-formulated research question in case study research is typically clear, focused, and complex enough to merit further detailed examination of the relevant case(s).

Propositions

Propositions, though not necessary in every case study, provide a direction by stating what we might expect to find in the data collected. They guide how data is collected and analyzed by helping researchers focus on specific aspects of the case. They are particularly important in explanatory case studies, which seek to understand the relationships among concepts within the studied phenomenon.

Units of analysis

The unit of analysis refers to the case, or the main entity or entities that are being analyzed in the study. In case study research, the unit of analysis can be an individual, a group, an organization, a decision, an event, or even a time period. It's crucial to clearly define the unit of analysis, as it shapes the qualitative data analysis process by allowing the researcher to analyze a particular case and synthesize analysis across multiple case studies to draw conclusions.

Argumentation

This refers to the inferential model that allows researchers to draw conclusions from the data. The researcher needs to ensure that there is a clear link between the data, the propositions (if any), and the conclusions drawn. This argumentation is what enables the researcher to make valid and credible inferences about the phenomenon under study.

Understanding and carefully considering these elements in the design phase of a case study can significantly enhance the quality of the research. It can help ensure that the study is methodologically sound and its findings contribute meaningful insights about the case.

Conducting a case study involves several steps, from defining the research question and selecting the case to collecting and analyzing data . This section outlines these key stages, providing a practical guide on how to conduct case study research.

Defining the research question

The first step in case study research is defining a clear, focused research question. This question should guide the entire research process, from case selection to analysis. It's crucial to ensure that the research question is suitable for a case study approach. Typically, such questions are exploratory or descriptive in nature and focus on understanding a phenomenon within its real-life context.

Selecting and defining the case

The selection of the case should be based on the research question and the objectives of the study. It involves choosing a unique example or a set of examples that provide rich, in-depth data about the phenomenon under investigation. After selecting the case, it's crucial to define it clearly, setting the boundaries of the case, including the time period and the specific context.

Previous research can help guide the case study design. When considering a case study, an example of a case could be taken from previous case study research and used to define cases in a new research inquiry. Considering recently published examples can help understand how to select and define cases effectively.

Developing a detailed case study protocol

A case study protocol outlines the procedures and general rules to be followed during the case study. This includes the data collection methods to be used, the sources of data, and the procedures for analysis. Having a detailed case study protocol ensures consistency and reliability in the study.

The protocol should also consider how to work with the people involved in the research context to grant the research team access to collecting data. As mentioned in previous sections of this guide, establishing rapport is an essential component of qualitative research as it shapes the overall potential for collecting and analyzing data.

Collecting data

Gathering data in case study research often involves multiple sources of evidence, including documents, archival records, interviews, observations, and physical artifacts. This allows for a comprehensive understanding of the case. The process for gathering data should be systematic and carefully documented to ensure the reliability and validity of the study.

Analyzing and interpreting data

The next step is analyzing the data. This involves organizing the data , categorizing it into themes or patterns , and interpreting these patterns to answer the research question. The analysis might also involve comparing the findings with prior research or theoretical propositions.

Writing the case study report

The final step is writing the case study report . This should provide a detailed description of the case, the data, the analysis process, and the findings. The report should be clear, organized, and carefully written to ensure that the reader can understand the case and the conclusions drawn from it.

Each of these steps is crucial in ensuring that the case study research is rigorous, reliable, and provides valuable insights about the case.

The type, depth, and quality of data in your study can significantly influence the validity and utility of the study. In case study research, data is usually collected from multiple sources to provide a comprehensive and nuanced understanding of the case. This section will outline the various methods of collecting data used in case study research and discuss considerations for ensuring the quality of the data.

Interviews are a common method of gathering data in case study research. They can provide rich, in-depth data about the perspectives, experiences, and interpretations of the individuals involved in the case. Interviews can be structured , semi-structured , or unstructured , depending on the research question and the degree of flexibility needed.

Observations

Observations involve the researcher observing the case in its natural setting, providing first-hand information about the case and its context. Observations can provide data that might not be revealed in interviews or documents, such as non-verbal cues or contextual information.

Documents and artifacts

Documents and archival records provide a valuable source of data in case study research. They can include reports, letters, memos, meeting minutes, email correspondence, and various public and private documents related to the case.

These records can provide historical context, corroborate evidence from other sources, and offer insights into the case that might not be apparent from interviews or observations.

Physical artifacts refer to any physical evidence related to the case, such as tools, products, or physical environments. These artifacts can provide tangible insights into the case, complementing the data gathered from other sources.

Ensuring the quality of data collection

Determining the quality of data in case study research requires careful planning and execution. It's crucial to ensure that the data is reliable, accurate, and relevant to the research question. This involves selecting appropriate methods of collecting data, properly training interviewers or observers, and systematically recording and storing the data. It also includes considering ethical issues related to collecting and handling data, such as obtaining informed consent and ensuring the privacy and confidentiality of the participants.

Data analysis

Analyzing case study research involves making sense of the rich, detailed data to answer the research question. This process can be challenging due to the volume and complexity of case study data. However, a systematic and rigorous approach to analysis can ensure that the findings are credible and meaningful. This section outlines the main steps and considerations in analyzing data in case study research.

Organizing the data

The first step in the analysis is organizing the data. This involves sorting the data into manageable sections, often according to the data source or the theme. This step can also involve transcribing interviews, digitizing physical artifacts, or organizing observational data.

Categorizing and coding the data

Once the data is organized, the next step is to categorize or code the data. This involves identifying common themes, patterns, or concepts in the data and assigning codes to relevant data segments. Coding can be done manually or with the help of software tools, and in either case, qualitative analysis software can greatly facilitate the entire coding process. Coding helps to reduce the data to a set of themes or categories that can be more easily analyzed.

Identifying patterns and themes

After coding the data, the researcher looks for patterns or themes in the coded data. This involves comparing and contrasting the codes and looking for relationships or patterns among them. The identified patterns and themes should help answer the research question.

Interpreting the data

Once patterns and themes have been identified, the next step is to interpret these findings. This involves explaining what the patterns or themes mean in the context of the research question and the case. This interpretation should be grounded in the data, but it can also involve drawing on theoretical concepts or prior research.

Verification of the data

The last step in the analysis is verification. This involves checking the accuracy and consistency of the analysis process and confirming that the findings are supported by the data. This can involve re-checking the original data, checking the consistency of codes, or seeking feedback from research participants or peers.

Like any research method , case study research has its strengths and limitations. Researchers must be aware of these, as they can influence the design, conduct, and interpretation of the study.

Understanding the strengths and limitations of case study research can also guide researchers in deciding whether this approach is suitable for their research question . This section outlines some of the key strengths and limitations of case study research.

Benefits include the following:

• Rich, detailed data: One of the main strengths of case study research is that it can generate rich, detailed data about the case. This can provide a deep understanding of the case and its context, which can be valuable in exploring complex phenomena.
• Flexibility: Case study research is flexible in terms of design , data collection , and analysis . A sufficient degree of flexibility allows the researcher to adapt the study according to the case and the emerging findings.
• Real-world context: Case study research involves studying the case in its real-world context, which can provide valuable insights into the interplay between the case and its context.
• Multiple sources of evidence: Case study research often involves collecting data from multiple sources , which can enhance the robustness and validity of the findings.

On the other hand, researchers should consider the following limitations:

• Generalizability: A common criticism of case study research is that its findings might not be generalizable to other cases due to the specificity and uniqueness of each case.
• Time and resource intensive: Case study research can be time and resource intensive due to the depth of the investigation and the amount of collected data.
• Complexity of analysis: The rich, detailed data generated in case study research can make analyzing the data challenging.
• Subjectivity: Given the nature of case study research, there may be a higher degree of subjectivity in interpreting the data , so researchers need to reflect on this and transparently convey to audiences how the research was conducted.

A case study is a research method that involves an in-depth examination and analysis of a particular phenomenon or case, such as an individual, organization, community, event, or situation.

It is a qualitative research approach that aims to provide a detailed and comprehensive understanding of the case being studied. Case studies typically involve multiple sources of data, including interviews, observations, documents, and artifacts, which are analyzed using various techniques, such as content analysis, thematic analysis, and grounded theory. The findings of a case study are often used to develop theories, inform policy or practice, or generate new research questions.

Types of Case Study

Types and Methods of Case Study are as follows:

Single-Case Study

A single-case study is an in-depth analysis of a single case. This type of case study is useful when the researcher wants to understand a specific phenomenon in detail.

For Example , A researcher might conduct a single-case study on a particular individual to understand their experiences with a particular health condition or a specific organization to explore their management practices. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of a single-case study are often used to generate new research questions, develop theories, or inform policy or practice.

Multiple-Case Study

A multiple-case study involves the analysis of several cases that are similar in nature. This type of case study is useful when the researcher wants to identify similarities and differences between the cases.

For Example, a researcher might conduct a multiple-case study on several companies to explore the factors that contribute to their success or failure. The researcher collects data from each case, compares and contrasts the findings, and uses various techniques to analyze the data, such as comparative analysis or pattern-matching. The findings of a multiple-case study can be used to develop theories, inform policy or practice, or generate new research questions.

Exploratory Case Study

An exploratory case study is used to explore a new or understudied phenomenon. This type of case study is useful when the researcher wants to generate hypotheses or theories about the phenomenon.

For Example, a researcher might conduct an exploratory case study on a new technology to understand its potential impact on society. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as grounded theory or content analysis. The findings of an exploratory case study can be used to generate new research questions, develop theories, or inform policy or practice.

Descriptive Case Study

A descriptive case study is used to describe a particular phenomenon in detail. This type of case study is useful when the researcher wants to provide a comprehensive account of the phenomenon.

For Example, a researcher might conduct a descriptive case study on a particular community to understand its social and economic characteristics. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of a descriptive case study can be used to inform policy or practice or generate new research questions.

Instrumental Case Study

An instrumental case study is used to understand a particular phenomenon that is instrumental in achieving a particular goal. This type of case study is useful when the researcher wants to understand the role of the phenomenon in achieving the goal.

For Example, a researcher might conduct an instrumental case study on a particular policy to understand its impact on achieving a particular goal, such as reducing poverty. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of an instrumental case study can be used to inform policy or practice or generate new research questions.

Case Study Data Collection Methods

Here are some common data collection methods for case studies:

Interviews involve asking questions to individuals who have knowledge or experience relevant to the case study. Interviews can be structured (where the same questions are asked to all participants) or unstructured (where the interviewer follows up on the responses with further questions). Interviews can be conducted in person, over the phone, or through video conferencing.

Observations

Observations involve watching and recording the behavior and activities of individuals or groups relevant to the case study. Observations can be participant (where the researcher actively participates in the activities) or non-participant (where the researcher observes from a distance). Observations can be recorded using notes, audio or video recordings, or photographs.

Documents can be used as a source of information for case studies. Documents can include reports, memos, emails, letters, and other written materials related to the case study. Documents can be collected from the case study participants or from public sources.

Surveys involve asking a set of questions to a sample of individuals relevant to the case study. Surveys can be administered in person, over the phone, through mail or email, or online. Surveys can be used to gather information on attitudes, opinions, or behaviors related to the case study.

Artifacts are physical objects relevant to the case study. Artifacts can include tools, equipment, products, or other objects that provide insights into the case study phenomenon.

How to conduct Case Study Research

Conducting a case study research involves several steps that need to be followed to ensure the quality and rigor of the study. Here are the steps to conduct case study research:

• Define the research questions: The first step in conducting a case study research is to define the research questions. The research questions should be specific, measurable, and relevant to the case study phenomenon under investigation.
• Select the case: The next step is to select the case or cases to be studied. The case should be relevant to the research questions and should provide rich and diverse data that can be used to answer the research questions.
• Collect data: Data can be collected using various methods, such as interviews, observations, documents, surveys, and artifacts. The data collection method should be selected based on the research questions and the nature of the case study phenomenon.
• Analyze the data: The data collected from the case study should be analyzed using various techniques, such as content analysis, thematic analysis, or grounded theory. The analysis should be guided by the research questions and should aim to provide insights and conclusions relevant to the research questions.

Purpose of Case Study

The purpose of a case study is to provide a detailed analysis of a specific phenomenon, issue, or problem in its real-life context. A case study is a qualitative research method that involves the in-depth exploration and analysis of a particular case, which can be an individual, group, organization, event, or community.

The primary purpose of a case study is to generate a comprehensive and nuanced understanding of the case, including its history, context, and dynamics. Case studies can help researchers to identify and examine the underlying factors, processes, and mechanisms that contribute to the case and its outcomes. This can help to develop a more accurate and detailed understanding of the case, which can inform future research, practice, or policy.

Case studies can also serve other purposes, including:

• Illustrating a theory or concept: Case studies can be used to illustrate and explain theoretical concepts and frameworks, providing concrete examples of how they can be applied in real-life situations.
• Developing hypotheses: Case studies can help to generate hypotheses about the causal relationships between different factors and outcomes, which can be tested through further research.
• Providing insight into complex issues: Case studies can provide insights into complex and multifaceted issues, which may be difficult to understand through other research methods.
• Informing practice or policy: Case studies can be used to inform practice or policy by identifying best practices, lessons learned, or areas for improvement.

Advantages of Case Study Research

There are several advantages of case study research, including:

• In-depth exploration: Case study research allows for a detailed exploration and analysis of a specific phenomenon, issue, or problem in its real-life context. This can provide a comprehensive understanding of the case and its dynamics, which may not be possible through other research methods.
• Rich data: Case study research can generate rich and detailed data, including qualitative data such as interviews, observations, and documents. This can provide a nuanced understanding of the case and its complexity.
• Holistic perspective: Case study research allows for a holistic perspective of the case, taking into account the various factors, processes, and mechanisms that contribute to the case and its outcomes. This can help to develop a more accurate and comprehensive understanding of the case.
• Theory development: Case study research can help to develop and refine theories and concepts by providing empirical evidence and concrete examples of how they can be applied in real-life situations.
• Practical application: Case study research can inform practice or policy by identifying best practices, lessons learned, or areas for improvement.
• Contextualization: Case study research takes into account the specific context in which the case is situated, which can help to understand how the case is influenced by the social, cultural, and historical factors of its environment.

Limitations of Case Study Research

There are several limitations of case study research, including:

• Limited generalizability : Case studies are typically focused on a single case or a small number of cases, which limits the generalizability of the findings. The unique characteristics of the case may not be applicable to other contexts or populations, which may limit the external validity of the research.
• Biased sampling: Case studies may rely on purposive or convenience sampling, which can introduce bias into the sample selection process. This may limit the representativeness of the sample and the generalizability of the findings.
• Subjectivity: Case studies rely on the interpretation of the researcher, which can introduce subjectivity into the analysis. The researcher’s own biases, assumptions, and perspectives may influence the findings, which may limit the objectivity of the research.
• Limited control: Case studies are typically conducted in naturalistic settings, which limits the control that the researcher has over the environment and the variables being studied. This may limit the ability to establish causal relationships between variables.
• Time-consuming: Case studies can be time-consuming to conduct, as they typically involve a detailed exploration and analysis of a specific case. This may limit the feasibility of conducting multiple case studies or conducting case studies in a timely manner.
• Resource-intensive: Case studies may require significant resources, including time, funding, and expertise. This may limit the ability of researchers to conduct case studies in resource-constrained settings.

Writing a Case Study

What is a case study?

A Case study is: 

• An in-depth research design that primarily uses a qualitative methodology but sometimes​​ includes quantitative methodology.
• Used to examine an identifiable problem confirmed through research.
• Used to investigate an individual, group of people, organization, or event.
• Used to mostly answer "how" and "why" questions.

What are the different types of case studies?

Note: These are the primary case studies. As you continue to research and learn

about case studies you will begin to find a robust list of different types. 

Who are your case study participants?

What is triangulation ? 

Validity and credibility are an essential part of the case study. Therefore, the researcher should include triangulation to ensure trustworthiness while accurately reflecting what the researcher seeks to investigate.

How to write a Case Study?

When developing a case study, there are different ways you could present the information, but remember to include the five parts for your case study.

What Is a Case Study?

Weighing the pros and cons of this method of research

Verywell / Colleen Tighe

• Pros and Cons

What Types of Case Studies Are Out There?

Where do you find data for a case study, how do i write a psychology case study.

A case study is an in-depth study of one person, group, or event. In a case study, nearly every aspect of the subject's life and history is analyzed to seek patterns and causes of behavior. Case studies can be used in many different fields, including psychology, medicine, education, anthropology, political science, and social work.

The point of a case study is to learn as much as possible about an individual or group so that the information can be generalized to many others. Unfortunately, case studies tend to be highly subjective, and it is sometimes difficult to generalize results to a larger population.

While case studies focus on a single individual or group, they follow a format similar to other types of psychology writing. If you are writing a case study, we got you—here are some rules of APA format to reference.  

At a Glance

A case study, or an in-depth study of a person, group, or event, can be a useful research tool when used wisely. In many cases, case studies are best used in situations where it would be difficult or impossible for you to conduct an experiment. They are helpful for looking at unique situations and allow researchers to gather a lot of˜ information about a specific individual or group of people. However, it's important to be cautious of any bias we draw from them as they are highly subjective.

What Are the Benefits and Limitations of Case Studies?

A case study can have its strengths and weaknesses. Researchers must consider these pros and cons before deciding if this type of study is appropriate for their needs.

One of the greatest advantages of a case study is that it allows researchers to investigate things that are often difficult or impossible to replicate in a lab. Some other benefits of a case study:

• Allows researchers to capture information on the 'how,' 'what,' and 'why,' of something that's implemented
• Gives researchers the chance to collect information on why one strategy might be chosen over another
• Permits researchers to develop hypotheses that can be explored in experimental research

On the other hand, a case study can have some drawbacks:

• It cannot necessarily be generalized to the larger population
• Cannot demonstrate cause and effect
• It may not be scientifically rigorous
• It can lead to bias

Researchers may choose to perform a case study if they want to explore a unique or recently discovered phenomenon. Through their insights, researchers develop additional ideas and study questions that might be explored in future studies.

It's important to remember that the insights from case studies cannot be used to determine cause-and-effect relationships between variables. However, case studies may be used to develop hypotheses that can then be addressed in experimental research.

Case Study Examples

There have been a number of notable case studies in the history of psychology. Much of  Freud's work and theories were developed through individual case studies. Some great examples of case studies in psychology include:

• Anna O : Anna O. was a pseudonym of a woman named Bertha Pappenheim, a patient of a physician named Josef Breuer. While she was never a patient of Freud's, Freud and Breuer discussed her case extensively. The woman was experiencing symptoms of a condition that was then known as hysteria and found that talking about her problems helped relieve her symptoms. Her case played an important part in the development of talk therapy as an approach to mental health treatment.
• Phineas Gage : Phineas Gage was a railroad employee who experienced a terrible accident in which an explosion sent a metal rod through his skull, damaging important portions of his brain. Gage recovered from his accident but was left with serious changes in both personality and behavior.
• Genie : Genie was a young girl subjected to horrific abuse and isolation. The case study of Genie allowed researchers to study whether language learning was possible, even after missing critical periods for language development. Her case also served as an example of how scientific research may interfere with treatment and lead to further abuse of vulnerable individuals.

Such cases demonstrate how case research can be used to study things that researchers could not replicate in experimental settings. In Genie's case, her horrific abuse denied her the opportunity to learn a language at critical points in her development.

This is clearly not something researchers could ethically replicate, but conducting a case study on Genie allowed researchers to study phenomena that are otherwise impossible to reproduce.

There are a few different types of case studies that psychologists and other researchers might use:

• Collective case studies : These involve studying a group of individuals. Researchers might study a group of people in a certain setting or look at an entire community. For example, psychologists might explore how access to resources in a community has affected the collective mental well-being of those who live there.
• Descriptive case studies : These involve starting with a descriptive theory. The subjects are then observed, and the information gathered is compared to the pre-existing theory.
• Explanatory case studies : These   are often used to do causal investigations. In other words, researchers are interested in looking at factors that may have caused certain things to occur.
• Exploratory case studies : These are sometimes used as a prelude to further, more in-depth research. This allows researchers to gather more information before developing their research questions and hypotheses .
• Instrumental case studies : These occur when the individual or group allows researchers to understand more than what is initially obvious to observers.
• Intrinsic case studies : This type of case study is when the researcher has a personal interest in the case. Jean Piaget's observations of his own children are good examples of how an intrinsic case study can contribute to the development of a psychological theory.

The three main case study types often used are intrinsic, instrumental, and collective. Intrinsic case studies are useful for learning about unique cases. Instrumental case studies help look at an individual to learn more about a broader issue. A collective case study can be useful for looking at several cases simultaneously.

The type of case study that psychology researchers use depends on the unique characteristics of the situation and the case itself.

There are a number of different sources and methods that researchers can use to gather information about an individual or group. Six major sources that have been identified by researchers are:

• Archival records : Census records, survey records, and name lists are examples of archival records.
• Direct observation : This strategy involves observing the subject, often in a natural setting . While an individual observer is sometimes used, it is more common to utilize a group of observers.
• Documents : Letters, newspaper articles, administrative records, etc., are the types of documents often used as sources.
• Interviews : Interviews are one of the most important methods for gathering information in case studies. An interview can involve structured survey questions or more open-ended questions.
• Participant observation : When the researcher serves as a participant in events and observes the actions and outcomes, it is called participant observation.
• Physical artifacts : Tools, objects, instruments, and other artifacts are often observed during a direct observation of the subject.

If you have been directed to write a case study for a psychology course, be sure to check with your instructor for any specific guidelines you need to follow. If you are writing your case study for a professional publication, check with the publisher for their specific guidelines for submitting a case study.

Here is a general outline of what should be included in a case study.

Section 1: A Case History

This section will have the following structure and content:

Background information : The first section of your paper will present your client's background. Include factors such as age, gender, work, health status, family mental health history, family and social relationships, drug and alcohol history, life difficulties, goals, and coping skills and weaknesses.

Description of the presenting problem : In the next section of your case study, you will describe the problem or symptoms that the client presented with.

Describe any physical, emotional, or sensory symptoms reported by the client. Thoughts, feelings, and perceptions related to the symptoms should also be noted. Any screening or diagnostic assessments that are used should also be described in detail and all scores reported.

Your diagnosis : Provide your diagnosis and give the appropriate Diagnostic and Statistical Manual code. Explain how you reached your diagnosis, how the client's symptoms fit the diagnostic criteria for the disorder(s), or any possible difficulties in reaching a diagnosis.

Section 2: Treatment Plan

This portion of the paper will address the chosen treatment for the condition. This might also include the theoretical basis for the chosen treatment or any other evidence that might exist to support why this approach was chosen.

• Cognitive behavioral approach : Explain how a cognitive behavioral therapist would approach treatment. Offer background information on cognitive behavioral therapy and describe the treatment sessions, client response, and outcome of this type of treatment. Make note of any difficulties or successes encountered by your client during treatment.
• Humanistic approach : Describe a humanistic approach that could be used to treat your client, such as client-centered therapy . Provide information on the type of treatment you chose, the client's reaction to the treatment, and the end result of this approach. Explain why the treatment was successful or unsuccessful.
• Psychoanalytic approach : Describe how a psychoanalytic therapist would view the client's problem. Provide some background on the psychoanalytic approach and cite relevant references. Explain how psychoanalytic therapy would be used to treat the client, how the client would respond to therapy, and the effectiveness of this treatment approach.
• Pharmacological approach : If treatment primarily involves the use of medications, explain which medications were used and why. Provide background on the effectiveness of these medications and how monotherapy may compare with an approach that combines medications with therapy or other treatments.

This section of a case study should also include information about the treatment goals, process, and outcomes.

When you are writing a case study, you should also include a section where you discuss the case study itself, including the strengths and limitiations of the study. You should note how the findings of your case study might support previous research. 

In your discussion section, you should also describe some of the implications of your case study. What ideas or findings might require further exploration? How might researchers go about exploring some of these questions in additional studies?

Need More Tips?

Here are a few additional pointers to keep in mind when formatting your case study:

• Never refer to the subject of your case study as "the client." Instead, use their name or a pseudonym.
• Read examples of case studies to gain an idea about the style and format.
• Remember to use APA format when citing references .

What the Case Study Method Really Teaches

• Nitin Nohria

Seven meta-skills that stick even if the cases fade from memory.

It’s been 100 years since Harvard Business School began using the case study method. Beyond teaching specific subject matter, the case study method excels in instilling meta-skills in students. This article explains the importance of seven such skills: preparation, discernment, bias recognition, judgement, collaboration, curiosity, and self-confidence.

During my decade as dean of Harvard Business School, I spent hundreds of hours talking with our alumni. To enliven these conversations, I relied on a favorite question: “What was the most important thing you learned from your time in our MBA program?”

What is a case study?

6 types of case studies, what is a business case study, what is a case study in research, what is a case study in psychology, what is the case study method, benefits of case studies, limitations of case studies, faqs about case studies.

A case study is a research process aimed at learning about a subject, an event or an organization. Case studies are use in business, the social sciences and healthcare.

A case study may focus on one observation or many. It can also examine a series of events or a single case. An effective case study tells a story and provides a conclusion.

Healthcare industries write reports on patients and diagnoses. Marketing case study examples , like the one below, highlight the benefits of a business product.

Now that you know what a case study is, let’s look at the six different types of case studies next.

There are six common types of case reports. Depending on your industry, you might use one of these types.

Descriptive case studies

Explanatory case studies, exploratory case reports, intrinsic case studies, instrumental case studies, collective case reports.

We go into more detail about each type of study in the guide below.

When you have an existing hypothesis, you can design a descriptive study. This type of report starts with a description. The aim is to find connections between the subject being studied and a theory.

Once these connections are found, the study can conclude. The results of this type of study will usually suggest how to develop a theory further.

A study like the one below has concrete results. A descriptive report would use the quantitative data as a suggestion for researching the subject deeply.

When an incident occurs in a field, an explanation is required. An explanatory report investigates the cause of the event. It will include explanations for that cause.

The study will also share details about the impact of the event. In most cases, this report will use evidence to predict future occurrences. The results of explanatory reports are definitive.

Note that there is no room for interpretation here. The results are absolute.

The study below is a good example. It explains how one brand used the services of another. It concludes by showing definitive proof that the collaboration was successful.

Another example of this study would be in the automotive industry. If a vehicle fails a test, an explanatory study will examine why. The results could show that the failure was because of a particular part.

An explanatory report is a self-contained document. An exploratory one is only the beginning of an investigation.

Exploratory cases act as the starting point of studies. This is usually conducted as a precursor to large-scale investigations. The research is used to suggest why further investigations are needed.

An exploratory study can also be used to suggest methods for further examination.

For example, the below analysis could have found inconclusive results. In that situation, it would be the basis for an in-depth study.

Intrinsic studies are more common in the field of psychology. These reports can also be conducted in healthcare or social work.

These types of studies focus on a unique subject, such as a patient. They can sometimes study groups close to the researcher.

The aim of such studies is to understand the subject better. This requires learning their history. The researcher will also examine how they interact with their environment.

For instance, if the case study below was about a unique brand, it could be an intrinsic study.

Once the study is complete, the researcher will have developed a better understanding of a phenomenon. This phenomenon will likely not have been studied or theorized about before.

Examples of intrinsic case analysis can be found across psychology. For example, Jean Piaget’s theories on cognitive development. He established the theory from intrinsic studies into his own children.

This is another type of study seen in medical and psychology fields. Instrumental reports are created to examine more than just the primary subject.

When research is conducted for an instrumental study, it is to provide the basis for a larger phenomenon. The subject matter is usually the best example of the phenomenon. This is why it is being studied.

Take the example of the fictional brand below.

Assume it’s examining lead generation strategies. It may want to show that visual marketing is the definitive lead generation tool. The brand can conduct an instrumental case study to examine this phenomenon.

Collective studies are based on instrumental case reports. These types of studies examine multiple reports.

There are a number of reasons why collective reports are created:

• To provide evidence for starting a new study
• To find pattens between multiple instrumental reports
• To find differences in similar types of cases
• Gain a deeper understanding of a complex phenomenon
• Understand a phenomenon from diverse contexts

A researcher could use multiple reports, like the one below, to build a collective case report.

A business or marketing case study aims at showcasing a successful partnership. This can be between a brand and a client. Or the case study can examine a brand’s project.

There is a perception that case studies are used to advertise a brand. But effective reports, like the one below, can show clients how a brand can support them.

Hubspot created a case study on a customer that successfully scaled its business. The report outlines the various Hubspot tools used to achieve these results.

Hubspot also added a video with testimonials from the client company’s employees.

So, what is the purpose of a case study for businesses? There is a lot of competition in the corporate world. Companies are run by people. They can be on the fence about which brand to work with.

Business reports  stand out aesthetically, as well. They use  brand colors  and brand fonts . Usually, a combination of the client’s and the brand’s.

With the Venngage  My Brand Kit  feature, businesses can automatically apply their brand to designs.

A business case study, like the one below, acts as social proof. This helps customers decide between your brand and your competitors.

Research is a necessary part of every case study. But specific research fields are required to create studies. These fields include user research, healthcare, education, or social work.

For example, this UX Design  report examined the public perception of a client. The brand researched and implemented new visuals to improve it. The study breaks down this research through lessons learned.

Clinical reports are a necessity in the medical field. These documents are used to share knowledge with other professionals. They also help examine new or unusual diseases or symptoms.

The pandemic has led to a significant increase in research. For example,  Spectrum Health  studied the value of health systems in the pandemic. They created the study by examining community outreach.

The pandemic has significantly impacted the field of education. This has led to numerous examinations on remote studying. There have also been studies on how students react to decreased peer communication.

Social work case reports often have a community focus. They can also examine public health responses. In certain regions, social workers study disaster responses.

You now know what case studies in various fields are. In the next step of our guide, we explain the case study method.

In the field of psychology, case studies focus on a particular subject. Psychology case histories also examine human behaviors.

Case reports search for commonalities between humans. They are also used to prescribe further research. Or these studies can elaborate on a solution for a behavioral ailment.

The American Psychology Association  has a number of case studies on real-life clients. Note how the reports are more text-heavy than a business case study.

Famous psychologists such as Sigmund Freud and Anna O popularised the use of case studies in the field. They did so by regularly interviewing subjects. Their detailed observations build the field of psychology.

It is important to note that psychological studies must be conducted by professionals. Psychologists, psychiatrists and therapists should be the researchers in these cases.

The case study method, or case method, is a learning technique where you’re presented with a real-world business challenge and asked how you’d solve it.

After working through it independently and with peers, you learn how the actual scenario unfolded. This approach helps develop problem-solving skills and practical knowledge.

This method often uses various data sources like interviews, observations, and documents to provide comprehensive insights. The below example would have been created after numerous interviews.

Case studies are largely qualitative. They analyze and describe phenomena. While some data is included, a case analysis is not quantitative.

There are a few steps in the case method. You have to start by identifying the subject of your study. Then determine what kind of research is required.

In natural sciences, case studies can take years to complete. Business reports, like this one, don’t take that long. A few weeks of interviews should be enough.

The case method will vary depending on the industry. Reports will also look different once produced.

As you will have seen, business reports are more colorful. The design is also more accessible . Healthcare and psychology reports are more text-heavy.

Designing case reports takes time and energy. So, is it worth taking the time to write them? Here are the benefits of creating case studies.

• Collects large amounts of information
• Helps formulate hypotheses
• Builds the case for further research
• Discovers new insights into a subject
• Builds brand trust and loyalty
• Engages customers through stories

For example, the business study below creates a story around a brand partnership. It makes for engaging reading. The study also shows evidence backing up the information.

We’ve shared the benefits of why studies are needed. We will also look at the limitations of creating them.

Related: How to Present a Case Study like a Pro (With Examples)

There are a few disadvantages to conducting a case analysis. The limitations will vary according to the industry.

• Responses from interviews are subjective
• Subjects may tailor responses to the researcher
• Studies can’t always be replicated
• In certain industries, analyses can take time and be expensive
• Risk of generalizing the results among a larger population

These are some of the common weaknesses of creating case reports. If you’re on the fence, look at the competition in your industry.

Other brands or professionals are building reports, like this example. In that case, you may want to do the same.

What makes a case study a case study?

A case study has a very particular research methodology. They are an in-depth study of a person or a group of individuals. They can also study a community or an organization. Case reports examine real-world phenomena within a set context.

How long should a case study be?

The length of studies depends on the industry. It also depends on the story you’re telling. Most case studies should be at least 500-1500 words long. But you can increase the length if you have more details to share.

What should you ask in a case study?

The one thing you shouldn’t ask is ‘yes’ or ‘no’ questions. Case studies are qualitative. These questions won’t give you the information you need.

Ask your client about the problems they faced. Ask them about solutions they found. Or what they think is the ideal solution. Leave room to ask them follow-up questions. This will help build out the study.

How to present a case study?

When you’re ready to present a case study, begin by providing a summary of the problem or challenge you were addressing. Follow this with an outline of the solution you implemented, and support this with the results you achieved, backed by relevant data. Incorporate visual aids like slides, graphs, and images to make your case study presentation more engaging and impactful.

Now you know what a case study means, you can begin creating one. These reports are a great tool for analyzing brands. They are also useful in a variety of other fields.

Use a visual communication platform like Venngage to design case studies. With Venngage’s templates, you can design easily. Create branded, engaging reports, all without design experience.

How to Write a Case Study: A Step-by-Step Guide (+ Examples)

by Todd Brehe

on Jan 3, 2024

If you want to learn how to write a case study that engages prospective clients, demonstrates that you can solve real business problems, and showcases the results you deliver, this guide will help.

We’ll give you a proven template to follow, show you how to conduct an engaging interview, and give you several examples and tips for best practices.

Let’s start with the basics.

What is a Case Study?

A business case study is simply a story about how you successfully delivered a solution to your client.

Case studies start with background information about the customer, describe problems they were facing, present the solutions you developed, and explain how those solutions positively impacted the customer’s business.

Do Marketing Case Studies Really Work?

Absolutely. A well-written case study puts prospective clients into the shoes of your paying clients, encouraging them to engage with you. Plus, they:

• Get shared “behind the lines” with decision makers you may not know;
• Leverage the power of “social proof” to encourage a prospective client to take a chance with your company;
• Build trust and foster likeability;
• Lessen the perceived risk of doing business with you and offer proof that your business can deliver results;
• Help prospects become aware of unrecognized problems;
• Show prospects experiencing similar problems that possible solutions are available (and you can provide said solutions);
• Make it easier for your target audience to find you when using Google and other search engines.

Case studies serve your clients too. For example, they can generate positive publicity and highlight the accomplishments of line staff to the management team. Your company might even throw in a new product/service discount, or a gift as an added bonus.

But don’t just take my word for it. Let’s look at a few statistics and success stories:

5 Winning Case Study Examples to Model

Before we get into the nuts and bolts of how to write a case study, let’s go over a few examples of what an excellent one looks like.

The five case studies listed below are well-written, well-designed, and incorporate a time-tested structure.

1. Lane Terralever and Pinnacle at Promontory

This case study example  from Lane Terralever  incorporates images to support the content and effectively uses subheadings to make the piece scannable.

2. WalkMe Mobile and Hulyo

This case study  from WalkMe Mobile  leads with an engaging headline and the three most important results the client was able to generate.

In the first paragraph, the writer expands the list of accomplishments encouraging readers to learn more.

3. CurationSuite Listening Engine

This is an example of a well-designed printable case study . The client, specific problem, and solution are called out in the left column and summarized succinctly.

4. Brain Traffic and ASAE

This long format case study (6 pages) from Brain Traffic  summarizes the challenges, solutions, and results prominently in the left column. It uses testimonials and headshots of the case study participants very effectively.

5. Adobe and Home Depot

This case study  from Adobe and Home Depot  is a great example of combining video, attention-getting graphics, and long form writing. It also uses testimonials and headshots well.

Now that we’ve gone over the basics and showed a few great case study examples you can use as inspiration, let’s roll up our sleeves and get to work.

A Case Study Structure That Pros Use

Let’s break down the structure of a compelling case study:

Choose Your Case Study Format

In this guide, we focus on written case studies. They’re affordable to create, and they have a proven track record. However, written case studies are just one of four case study formats to consider:

• Infographic

If you have the resources, video (like the Adobe and Home Depot example above) and podcast case studies can be very compelling. Hearing a client discuss in his or her own words how your company helped is an effective content marketing strategy

Infographic case studies are usually one-page images that summarize the challenge, proposed solution, and results. They tend to work well on social media.

Follow a Tried-and-True Case Study Template

The success story structure we’re using incorporates a “narrative” or “story arc” designed to suck readers in and captivate their interest.

Note:  I recommend creating a blog post or landing page on your website that includes the text from your case study, along with a downloadable PDF. Doing so helps people find your content when they perform Google and other web searches.

There are a few simple SEO strategies that you can apply to your blog post that will optimize your chances of being found. I’ll include those tips below.

Craft a Compelling Headline

The headline should capture your audience’s attention quickly. Include the most important result you achieved, the client’s name, and your company’s name. Create several examples, mull them over a bit, then pick the best one. And, yes, this means writing the headline is done at the very end.

SEO  Tip:  Let’s say your firm provided “video editing services” and you want to target this primary keyword. Include it, your company name, and your client’s name in the case study title.

Write the Executive Summary

This is a mini-narrative using an abbreviated version of the Challenge + Solution + Results model (3-4 short paragraphs). Write this after you complete the case study.

SEO  Tip:  Include your primary keyword in the first paragraph of the Executive Summary.

Provide the Client’s Background

Introduce your client to the reader and create context for the story.

List the Customer’s Challenges and Problems

Vividly describe the situation and problems the customer was dealing with, before working with you.

SEO  Tip:  To rank on page one of Google for our target keyword, review the questions listed in the “People also ask” section at the top of Google’s search results. If you can include some of these questions and their answers into your case study, do so. Just make sure they fit with the flow of your narrative.

Detail Your Solutions

Explain the product or service your company provided, and spell out how it alleviated the client’s problems. Recap how the solution was delivered and implemented. Describe any training needed and the customer’s work effort.

Show Your Results

Detail what you accomplished for the customer and the impact your product/service made. Objective, measurable results that resonate with your target audience are best.

List Future Plans

Share how your client might work with your company in the future.

Give a Call-to-Action

Clearly detail what you want the reader to do at the end of your case study.

Talk About You

Include a “press release-like” description of your client’s organization, with a link to their website. For your printable document, add an “About” section with your contact information.

And that’s it. That’s the basic structure of any good case study.

Now, let’s go over how to get the information you’ll use in your case study.

How to Conduct an Engaging Case Study Interview

One of the best parts of creating a case study is talking with your client about the experience. This is a fun and productive way to learn what your company did well, and what it can improve on, directly from your customer’s perspective.

Here are some suggestions for conducting great case study interviews:

When Choosing a Case Study Subject, Pick a Raving Fan

Your sales and marketing team should know which clients are vocal advocates willing to talk about their experiences. Your customer service and technical support teams should be able to contribute suggestions.

Clients who are experts with your product/service make solid case study candidates. If you sponsor an online community, look for product champions who post consistently and help others.

When selecting a candidate, think about customer stories that would appeal to your target audience. For example, let’s say your sales team is consistently bumping into prospects who are excited about your solution, but are slow to pull the trigger and do business with you.

In this instance, finding a client who felt the same way, but overcame their reluctance and contracted with you anyway, would be a compelling story to capture and share.

Prepping for the Interview

If you’ve ever seen an Oprah interview, you’ve seen a master who can get almost anyone to open up and talk. Part of the reason is that she and her team are disciplined about planning.

Before conducting a case study interview, talk to your own team about the following:

• What’s unique about the client (location, size, industry, etc.) that will resonate with our prospects?
• Why did the customer select us?
• How did we help the client?
• What’s unique about this customer’s experience?
• What problems did we solve?
• Were any measurable, objective results generated?
• What do we want readers to do after reading this case study analysis?

Pro Tip:  Tee up your client. Send them the questions in advance.

Providing questions to clients before the interview helps them prepare, gather input from other colleagues if needed, and feel more comfortable because they know what to expect.

In a moment, I’ll give you an exhaustive list of interview questions. But don’t send them all. Instead, pare the list down to one or two questions in each section and personalize them for your customer.

Nailing the Client Interview

Decide how you’ll conduct the interview. Will you call the client, use Skype or Facetime, or meet in person? Whatever mode you choose, plan the process in advance.

Make sure you record the conversation. It’s tough to lead an interview, listen to your contact’s responses, keep the conversation flowing, write notes, and capture all that the person is saying.

A recording will make it easier to write the client’s story later. It’s also useful for other departments in your company (management, sales, development, etc.) to hear real customer feedback.

Use open-ended questions that spur your contact to talk and share. Here are some real-life examples:

Introduction

• Recap the purpose of the call. Confirm how much time your contact has to talk (30-45 minutes is preferable).
• Confirm the company’s location, number of employees, years in business, industry, etc.
• What’s the contact’s background, title, time with the company, primary responsibilities, and so on?

Initial Challenges

• Describe the situation at your company before engaging with us?
• What were the initial problems you wanted to solve?
• What was the impact of those problems?
• When did you realize you had to take some action?
• What solutions did you try?
• What solutions did you implement?
• What process did you go through to make a purchase?
• How did the implementation go?
• How would you describe the work effort required of your team?
• If training was involved, how did that go?

Results, Improvements, Progress

• When did you start seeing improvements?
• What were the most valuable results?
• What did your team like best about working with us?
• Would you recommend our solution/company? Why?

Future Plans

• How do you see our companies working together in the future?

Honest Feedback

• Our company is very focused on continual improvement. What could we have done differently to make this an even better experience?
• What would you like us to add or change in our product/service?

During the interview, use your contact’s responses to guide the conversation.

Once the interview is complete, it’s time to write your case study.

How to Write a Case Study… Effortlessly

Case study writing is not nearly as difficult as many people make it out to be. And you don’t have to be Stephen King to do professional work. Here are a few tips:

• Use the case study structure that we outlined earlier, but write these sections first: company background, challenges, solutions, and results.
• Write the headline, executive summary, future plans, and call-to-action (CTA) last.
• In each section, include as much content from your interview as you can. Don’t worry about editing at this point
• Tell the story by discussing their trials and tribulations.
• Stay focused on the client and the results they achieved.
• Make their organization and employees shine.
• When including information about your company, frame your efforts in a supporting role.

Also, make sure to do the following:

Add Testimonials, Quotes, and Visuals

The more you can use your contact’s words to describe the engagement, the better. Weave direct quotes throughout your narrative.

Strive to be conversational when you’re writing case studies, as if you’re talking to a peer.

Include images in your case study that visually represent the content and break up the text. Photos of the company, your contact, and other employees are ideal.

If you need to incorporate stock photos, here are three resources:

• Deposit p hotos

And if you need more, check out Smart Blogger’s excellent resource: 17 Sites with High-Quality, Royalty-Free Stock Photos .

Proofread and Tighten Your Writing

Make sure there are no grammar, spelling, or punctuation errors. If you need help, consider using a grammar checker tool like Grammarly .

My high school English teacher’s mantra was “tighten your writing.” She taught that impactful writing is concise and free of weak, unnecessary words . This takes effort and discipline, but will make your writing stronger.

Also, keep in mind that we live in an attention-diverted society. Before your audience will dive in and read each paragraph, they’ll first scan your work.  Use subheadings  to summarize information, convey meaning quickly, and pull the reader in.

Be Sure to Use Best Practices

Consider applying the following best practices to your case study:

• Stay laser-focused on your client and the results they were able to achieve.
• Even if your audience is technical, minimize the use of industry jargon . If you use acronyms, explain them.
• Leave out the selling and advertising.
• Don’t write like a Shakespearean wannabe. Write how people speak. Write to be understood.
• Clear and concise writing is not only more understandable, it inspires trust. Don’t ramble.
• Weave your paragraphs together so that each sentence is dependent on the one before and after it.
• Include a specific case study call-to-action (CTA).
• A recommended case study length is 2-4 pages.
• Commit to building a library of case studies.

Get Client Approval

After you have a final draft, send it to the client for review and approval. Incorporate any edits they suggest.

Use or modify the following “Consent to Publish” form to get the client’s written sign-off:

Consent to Publish

Case Study  Title:

I hereby confirm that I have reviewed the case study listed above and on behalf of the [Company Name], I provide full permission for the work to be published, in whole or in part, for the life of the work, in all languages and all formats by [Company publishing the case study].

By signing this form, I affirm that I am authorized to grant full permission.

Company Name:

E-mail Address:

Common Case Study Questions (& Answers)

We’ll wrap things up with a quick Q&A. If you have a question I didn’t answer, be sure to leave it in a blog comment below.

Should I worry about print versions of my case studies?

Absolutely.

As we saw in the CurationSuite  and Brain Traffic  examples earlier, case studies get downloaded, printed, and shared. Prospects can and will judge your book by its cover.

So, make sure your printed case study is eye-catching and professionally designed. Hire a designer  if necessary.

Why are good case studies so effective?

Case studies work because people trust them.

They’re not ads, they’re not press releases, and they’re not about how stellar your company is.

Plus, everyone likes spellbinding stories with a hero [your client], a conflict [challenges], and a riveting resolution [best solution and results].

How do I promote my case study?

After you’ve written your case study and received the client’s approval to use it, you’ll want to get it in front of as many eyes as possible.

Try the following:

• Make sure your case studies can be easily found on your company’s homepage.
• Tweet and share the case study on your various social media accounts.
• Have your sales team use the case study as a reason to call on potential customers. For example: “Hi [prospect], we just published a case study on Company A. They were facing some of the same challenges I believe your firm is dealing with. I’m going to e-mail you a copy. Let me know what you think.”
• Distribute printed copies at trade shows, seminars, or during sales presentations.
• If you’re bidding on a job and have to submit a quote or a Request for Proposal (RFP), include relevant case studies as supporting documents.

Ready to Write a Case Study That Converts?

If you want to stand out and you want to win business, case studies should be an integral part of your sales and marketing efforts.

Hopefully, this guide answered some of your questions and laid out a path that will make it faster and easier for your team to create professional, sales-generating content.

Now it’s time to take action and get started. Gather your staff, select a client, and ask a contact to participate. Plan your interview and lead an engaging conversation. Write up your client’s story, make them shine, and then share it.

Get better at the case study process by doing it more frequently. Challenge yourself to write at least one case study every two months.

As you do, you’ll be building a valuable repository of meaningful, powerful content. These success stories will serve your business in countless ways, and for years to come.

How to Write a Case Study - All You Wanted to Know

What do you study in your college? If you are a psychology, sociology, or anthropology student, we bet you might be familiar with what a case study is. This research method is used to study a certain person, group, or situation. In this guide from our dissertation writing service , you will learn how to write a case study professionally, from researching to citing sources properly. Also, we will explore different types of case studies and show you examples — so that you won’t have any other questions left.

What Is a Case Study?

A case study is a subcategory of research design which investigates problems and offers solutions. Case studies can range from academic research studies to corporate promotional tools trying to sell an idea—their scope is quite vast.

What Is the Difference Between a Research Paper and a Case Study?

While research papers turn the reader’s attention to a certain problem, case studies go even further. Case study guidelines require students to pay attention to details, examining issues closely and in-depth using different research methods. For example, case studies may be used to examine court cases if you study Law, or a patient's health history if you study Medicine. Case studies are also used in Marketing, which are thorough, empirically supported analysis of a good or service's performance. Well-designed case studies can be valuable for prospective customers as they can identify and solve the potential customers pain point.

Case studies involve a lot of storytelling – they usually examine particular cases for a person or a group of people. This method of research is very helpful, as it is very practical and can give a lot of hands-on information. Most commonly, the length of the case study is about 500-900 words, which is much less than the length of an average research paper.

The structure of a case study is very similar to storytelling. It has a protagonist or main character, which in your case is actually a problem you are trying to solve. You can use the system of 3 Acts to make it a compelling story. It should have an introduction, rising action, a climax where transformation occurs, falling action, and a solution.

Here is a rough formula for you to use in your case study:

Problem (Act I): > Solution (Act II) > Result (Act III) > Conclusion.

Types of Case Studies

The purpose of a case study is to provide detailed reports on an event, an institution, a place, future customers, or pretty much anything. There are a few common types of case study, but the type depends on the topic. The following are the most common domains where case studies are needed:

• Historical case studies are great to learn from. Historical events have a multitude of source info offering different perspectives. There are always modern parallels where these perspectives can be applied, compared, and thoroughly analyzed.
• Problem-oriented case studies are usually used for solving problems. These are often assigned as theoretical situations where you need to immerse yourself in the situation to examine it. Imagine you’re working for a startup and you’ve just noticed a significant flaw in your product’s design. Before taking it to the senior manager, you want to do a comprehensive study on the issue and provide solutions. On a greater scale, problem-oriented case studies are a vital part of relevant socio-economic discussions.
• Cumulative case studies collect information and offer comparisons. In business, case studies are often used to tell people about the value of a product.
• Critical case studies explore the causes and effects of a certain case.
• Illustrative case studies describe certain events, investigating outcomes and lessons learned.

Case Study Format

The case study format is typically made up of eight parts:

• Executive Summary. Explain what you will examine in the case study. Write an overview of the field you’re researching. Make a thesis statement and sum up the results of your observation in a maximum of 2 sentences.
• Background. Provide background information and the most relevant facts. Isolate the issues.
• Case Evaluation. Isolate the sections of the study you want to focus on. In it, explain why something is working or is not working.
• Proposed Solutions. Offer realistic ways to solve what isn’t working or how to improve its current condition. Explain why these solutions work by offering testable evidence.
• Conclusion. Summarize the main points from the case evaluations and proposed solutions. 6. Recommendations. Talk about the strategy that you should choose. Explain why this choice is the most appropriate.
• Implementation. Explain how to put the specific strategies into action.
• References. Provide all the citations.

How to Write a Case Study

Let's discover how to write a case study.

Setting Up the Research

When writing a case study, remember that research should always come first. Reading many different sources and analyzing other points of view will help you come up with more creative solutions. You can also conduct an actual interview to thoroughly investigate the customer story that you'll need for your case study. Including all of the necessary research, writing a case study may take some time. The research process involves doing the following:

• Define your objective. Explain the reason why you’re presenting your subject. Figure out where you will feature your case study; whether it is written, on video, shown as an infographic, streamed as a podcast, etc.
• Determine who will be the right candidate for your case study. Get permission, quotes, and other features that will make your case study effective. Get in touch with your candidate to see if they approve of being part of your work. Study that candidate’s situation and note down what caused it.
• Identify which various consequences could result from the situation. Follow these guidelines on how to start a case study: surf the net to find some general information you might find useful.
• Make a list of credible sources and examine them. Seek out important facts and highlight problems. Always write down your ideas and make sure to brainstorm.
• Focus on several key issues – why they exist, and how they impact your research subject. Think of several unique solutions. Draw from class discussions, readings, and personal experience. When writing a case study, focus on the best solution and explore it in depth. After having all your research in place, writing a case study will be easy. You may first want to check the rubric and criteria of your assignment for the correct case study structure.

Although your instructor might be looking at slightly different criteria, every case study rubric essentially has the same standards. Your professor will want you to exhibit 8 different outcomes:

• Correctly identify the concepts, theories, and practices in the discipline.
• Identify the relevant theories and principles associated with the particular study.
• Evaluate legal and ethical principles and apply them to your decision-making.
• Recognize the global importance and contribution of your case.
• Construct a coherent summary and explanation of the study.
• Demonstrate analytical and critical-thinking skills.
• Explain the interrelationships between the environment and nature.
• Integrate theory and practice of the discipline within the analysis.

Case Study Outline

Let's look at the structure of an outline based on the issue of the alcoholic addiction of 30 people.

Introduction

• Statement of the issue: Alcoholism is a disease rather than a weakness of character.
• Presentation of the problem: Alcoholism is affecting more than 14 million people in the USA, which makes it the third most common mental illness there.
• Explanation of the terms: In the past, alcoholism was commonly referred to as alcohol dependence or alcohol addiction. Alcoholism is now the more severe stage of this addiction in the disorder spectrum.
• Hypotheses: Drinking in excess can lead to the use of other drugs.
• Importance of your story: How the information you present can help people with their addictions.
• Background of the story: Include an explanation of why you chose this topic.
• Presentation of analysis and data: Describe the criteria for choosing 30 candidates, the structure of the interview, and the outcomes.
• Strong argument 1: ex. X% of candidates dealing with anxiety and depression...
• Strong argument 2: ex. X amount of people started drinking by their mid-teens.
• Strong argument 3: ex. X% of respondents’ parents had issues with alcohol.
• Concluding statement: I have researched if alcoholism is a disease and found out that…
• Recommendations: Ways and actions for preventing alcohol use.

Writing a Case Study Draft

After you’ve done your case study research and written the outline, it’s time to focus on the draft. In a draft, you have to develop and write your case study by using: the data which you collected throughout the research, interviews, and the analysis processes that were undertaken. Follow these rules for the draft:

Use Data to Illustrate Key Points in Your Case Study

Even though your case study is a story, it should be based on evidence. Use as much data as possible to illustrate your point. Without the right data, your case study may appear weak and the readers may not be able to relate to your issue as much as they should. Let's see the examples from essay writing service :

‍ With data: Alcoholism is affecting more than 14 million people in the USA, which makes it the third most common mental illness there. Without data: A lot of people suffer from alcoholism in the United States.

Try to include as many credible sources as possible. You may have terms or sources that could be hard for other cultures to understand. If this is the case, you should include them in the appendix or Notes for the Instructor or Professor.

Finalizing the Draft: Checklist

After you finish drafting your case study, polish it up by answering these ‘ask yourself’ questions and think about how to end your case study:

• Check that you follow the correct case study format, also in regards to text formatting.
• Check that your work is consistent with its referencing and citation style.
• Micro-editing — check for grammar and spelling issues.
• Macro-editing — does ‘the big picture’ come across to the reader? Is there enough raw data, such as real-life examples or personal experiences? Have you made your data collection process completely transparent? Does your analysis provide a clear conclusion, allowing for further research and practice?

Problems to avoid:

• Overgeneralization – Do not go into further research that deviates from the main problem.
• Failure to Document Limitations – Just as you have to clearly state the limitations of a general research study, you must describe the specific limitations inherent in the subject of analysis.
• Failure to Extrapolate All Possible Implications – Just as you don't want to over-generalize from your case study findings, you also have to be thorough in the consideration of all possible outcomes or recommendations derived from your findings.

How to Create a Title Page and Cite a Case Study

Let's see how to create an awesome title page.

Your title page depends on the prescribed citation format. The title page should include:

• A title that attracts some attention and describes your study
• The title should have the words “case study” in it
• The title should range between 5-9 words in length
• Your name and contact information
• Your finished paper should be only 500 to 1,500 words in length.With this type of assignment, write effectively and avoid fluff

Here is a template for the APA and MLA format title page:

There are some cases when you need to cite someone else's study in your own one – therefore, you need to master how to cite a case study. A case study is like a research paper when it comes to citations. You can cite it like you cite a book, depending on what style you need.

Citation Example in MLA ‍ Hill, Linda, Tarun Khanna, and Emily A. Stecker. HCL Technologies. Boston: Harvard Business Publishing, 2008. Print.

Citation Example in APA ‍ Hill, L., Khanna, T., & Stecker, E. A. (2008). HCL Technologies. Boston: Harvard Business Publishing.

Citation Example in Chicago Hill, Linda, Tarun Khanna, and Emily A. Stecker. HCL Technologies.

Case Study Examples

To give you an idea of a professional case study example, we gathered and linked some below.

Eastman Kodak Case Study

Case Study Example: Audi Trains Mexican Autoworkers in Germany

To conclude, a case study is one of the best methods of getting an overview of what happened to a person, a group, or a situation in practice. It allows you to have an in-depth glance at the real-life problems that businesses, healthcare industry, criminal justice, etc. may face. This insight helps us look at such situations in a different light. This is because we see scenarios that we otherwise would not, without necessarily being there.

5 Benefits of Learning Through the Case Study Method

• 28 Nov 2023

While several factors make HBS Online unique —including a global Community and real-world outcomes —active learning through the case study method rises to the top.

In a 2023 City Square Associates survey, 74 percent of HBS Online learners who also took a course from another provider said HBS Online’s case method and real-world examples were better by comparison.

Here’s a primer on the case method, five benefits you could gain, and how to experience it for yourself.

Access your free e-book today.

What Is the Harvard Business School Case Study Method?

The case study method , or case method , is a learning technique in which you’re presented with a real-world business challenge and asked how you’d solve it. After working through it yourself and with peers, you’re told how the scenario played out.

HBS pioneered the case method in 1922. Shortly before, in 1921, the first case was written.

“How do you go into an ambiguous situation and get to the bottom of it?” says HBS Professor Jan Rivkin, former senior associate dean and chair of HBS's master of business administration (MBA) program, in a video about the case method . “That skill—the skill of figuring out a course of inquiry to choose a course of action—that skill is as relevant today as it was in 1921.”

Originally developed for the in-person MBA classroom, HBS Online adapted the case method into an engaging, interactive online learning experience in 2014.

In HBS Online courses , you learn about each case from the business professional who experienced it. After reviewing their videos, you’re prompted to take their perspective and explain how you’d handle their situation.

You then get to read peers’ responses, “star” them, and comment to further the discussion. Afterward, you learn how the professional handled it and their key takeaways.

HBS Online’s adaptation of the case method incorporates the famed HBS “cold call,” in which you’re called on at random to make a decision without time to prepare.

“Learning came to life!” said Sheneka Balogun , chief administration officer and chief of staff at LeMoyne-Owen College, of her experience taking the Credential of Readiness (CORe) program . “The videos from the professors, the interactive cold calls where you were randomly selected to participate, and the case studies that enhanced and often captured the essence of objectives and learning goals were all embedded in each module. This made learning fun, engaging, and student-friendly.”

If you’re considering taking a course that leverages the case study method, here are five benefits you could experience.

5 Benefits of Learning Through Case Studies

1. take new perspectives.

The case method prompts you to consider a scenario from another person’s perspective. To work through the situation and come up with a solution, you must consider their circumstances, limitations, risk tolerance, stakeholders, resources, and potential consequences to assess how to respond.

Taking on new perspectives not only can help you navigate your own challenges but also others’. Putting yourself in someone else’s situation to understand their motivations and needs can go a long way when collaborating with stakeholders.

2. Hone Your Decision-Making Skills

Another skill you can build is the ability to make decisions effectively . The case study method forces you to use limited information to decide how to handle a problem—just like in the real world.

Throughout your career, you’ll need to make difficult decisions with incomplete or imperfect information—and sometimes, you won’t feel qualified to do so. Learning through the case method allows you to practice this skill in a low-stakes environment. When facing a real challenge, you’ll be better prepared to think quickly, collaborate with others, and present and defend your solution.

3. Become More Open-Minded

As you collaborate with peers on responses, it becomes clear that not everyone solves problems the same way. Exposing yourself to various approaches and perspectives can help you become a more open-minded professional.

When you’re part of a diverse group of learners from around the world, your experiences, cultures, and backgrounds contribute to a range of opinions on each case.

On the HBS Online course platform, you’re prompted to view and comment on others’ responses, and discussion is encouraged. This practice of considering others’ perspectives can make you more receptive in your career.

“You’d be surprised at how much you can learn from your peers,” said Ratnaditya Jonnalagadda , a software engineer who took CORe.

In addition to interacting with peers in the course platform, Jonnalagadda was part of the HBS Online Community , where he networked with other professionals and continued discussions sparked by course content.

“You get to understand your peers better, and students share examples of businesses implementing a concept from a module you just learned,” Jonnalagadda said. “It’s a very good way to cement the concepts in one's mind.”

4. Enhance Your Curiosity

One byproduct of taking on different perspectives is that it enables you to picture yourself in various roles, industries, and business functions.

“Each case offers an opportunity for students to see what resonates with them, what excites them, what bores them, which role they could imagine inhabiting in their careers,” says former HBS Dean Nitin Nohria in the Harvard Business Review . “Cases stimulate curiosity about the range of opportunities in the world and the many ways that students can make a difference as leaders.”

Through the case method, you can “try on” roles you may not have considered and feel more prepared to change or advance your career .

5. Build Your Self-Confidence

Finally, learning through the case study method can build your confidence. Each time you assume a business leader’s perspective, aim to solve a new challenge, and express and defend your opinions and decisions to peers, you prepare to do the same in your career.

According to a 2022 City Square Associates survey , 84 percent of HBS Online learners report feeling more confident making business decisions after taking a course.

“Self-confidence is difficult to teach or coach, but the case study method seems to instill it in people,” Nohria says in the Harvard Business Review . “There may well be other ways of learning these meta-skills, such as the repeated experience gained through practice or guidance from a gifted coach. However, under the direction of a masterful teacher, the case method can engage students and help them develop powerful meta-skills like no other form of teaching.”

How to Experience the Case Study Method

If the case method seems like a good fit for your learning style, experience it for yourself by taking an HBS Online course. Offerings span eight subject areas, including:

• Business essentials
• Leadership and management
• Entrepreneurship and innovation
• Digital transformation
• Finance and accounting

Case Study | Definition, Examples & Methods

Published on 5 May 2022 by Shona McCombes . Revised on 30 January 2023.

A case study is a detailed study of a specific subject, such as a person, group, place, event, organisation, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.

A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating, and understanding different aspects of a research problem .

Table of contents

When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyse the case.

A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.

Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.

You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.

Prevent plagiarism, run a free check.

Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:

• Provide new or unexpected insights into the subject
• Challenge or complicate existing assumptions and theories
• Propose practical courses of action to resolve a problem
• Open up new directions for future research

Unlike quantitative or experimental research, a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.

If you find yourself aiming to simultaneously investigate and solve an issue, consider conducting action research . As its name suggests, action research conducts research and takes action at the same time, and is highly iterative and flexible. 

However, you can also choose a more common or representative case to exemplify a particular category, experience, or phenomenon.

While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:

• Exemplify a theory by showing how it explains the case under investigation
• Expand on a theory by uncovering new concepts and ideas that need to be incorporated
• Challenge a theory by exploring an outlier case that doesn’t fit with established assumptions

To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.

There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews, observations, and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data .

The aim is to gain as thorough an understanding as possible of the case and its context.

In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.

How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis, with separate sections or chapters for the methods , results , and discussion .

Others are written in a more narrative style, aiming to explore the case from various angles and analyse its meanings and implications (for example, by using textual analysis or discourse analysis ).

In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.

9 Components of a Case Study You Absolutely Need to Include

Updated July 2024: SaaS case studies are essential for demonstrating the value of your products and showcasing the success your customers have experienced. To streamline the creation of these case studies, adhering to a specific format is vital. In this post, discover the 9 key components of a case study that you need to include.

This is the first post in a 9-part series on how to write a B2B case study .

Components of a case study : must-have elements for success

1. an engaging executive summary.

One of the most crucial components of a case study is a compelling executive summary . It tells your potential customer what to expect and how they might be able to relate to the information provided. Begin by introducing your customer and their challenges. Then, emphasize how your B2B SaaS company helped deliver the right solution. Finally, include a preview of the outcomes your customer achieved with your products.

2. Outline your customer’s challenges

Illustrating the obstacles your customer faced that prompted them to seek out a B2B SaaS solution is one of the most crucial components of a case study. For example, maybe previous solution was a drain on time, resources or budgets.

This section is an ideal spot to use a customer quote and let them share their story in their words. Remember to paint your customer in a positive light. Focus on how they wanted to improve their business and avoid overly negative language.

3. Lead your reader along your customer’s journey

Help your reader picture themselves in your customer’s shoes. Lay out the steps your customer took to try to solve their problem, including an overview of the other products they investigated before they decided on yours. But be mindful not to toot your own horn—you’re simply recapping the facts.

4. The moment of discovery

The core components of a case study wouldn’t be complete without a section on how your customer decided on your specific B2B SaaS solution. First, provide insight into which of their business requirements it met. Then include any other reasons the partnership was a good fit—perhaps your companies shared similar organizational values.

This is an area where case study testimonials make for powerful storytelling . They allow you to set your case study up to dive into how you and your product solved your customer’s challenges.

5. Spend some time on the solution

In the “solution” component of your case study, you get to pitch your products without the fear of sounding like a used car salesman. Remember, you didn’t rush in and save the day—this is about your customer’s goals and how your solution helped them reach their objectives. As a result, you simply need to outline the products your customer purchased and the benefits they provided.

6. Walk your reader through the implementation

Change can be daunting, especially when it comes to the unknown, so it’s crucial that you give your reader a clear sense of how the implementation process went for your customer. For example, if problems arose, don’t be afraid to be transparent about them, but tie the storyline back to how you and your customer overcame the challenges. This is one of the most important components of a case study, and is an opportunity to let your customer service shine.

7. Celebrate your customer’s results

77% of SaaS companies include metrics in at least 50% of their case studies . Metrics are where you can show off the data—hard numbers like revenue gains and time saved that illustrate the return on investment your customer gained from your solution. Showcase how well your products solved the customer’s problems. Find out what to do if you don’t have case study metrics to work with.

8. Close the loop with a call to action

Using the right components of a case study so far has helped keep your reader’s attention until the end of the piece, creating an important opportunity for you to guide them to the next step you want them to take. You can accomplish this by including a clear call to action (CTA) that speaks directly to them at the end of your B2B SaaS case study. See these case study CTA examples to learn how to make your calls to action stand out.

9. Don’t get too caught up in using the perfect format

A lot of experts will tell you that your content needs to include all of the components of a case study and follow a structured formula. But don’t stress over this.

A creative story doesn’t lock itself into anything too prescriptive. And you don’t have to chunk your content into specific modules like some ’90s business plan. The most interesting and compelling stories take a creative approach to case study layout , and they play with perspective.

9 components of a case study: did you include them all?

Now that you know the 9 parts of a case study, take a look back through your own case studies. Have you included each of the components?

And last, but certainly not least, have you squeezed every last ounce of value from your case studies? Here are 13 ways to repurpose your case studies for maximum results.

Case Study Format

Following are the main Components/Parts of a Case Study;

Executive Summary

Introduction, alternatives and decision criteria, recommendations and implementation plan, conclusion and references, citing sources.

Writing a case study is not a simple process as it can take several months to write it successfully. There are many stages you need to complete first and after that, you finally come at the stage of writing your case study like selecting the topic, a lot of research ( qualitative research, quantitative research or interview with subjects etc), etc. While writing a case study, bear in mind that all the case studies aren’t the same for sure and vary largely in size, type, and design. It is necessary for a writer to follow a proper case study format while writing it, no matter what.

If you are going to write your very first case study, you need to know that every case study has a specific format, as mentioned above. Students or businesses all over the globe must follow that format in order to make their case study successful. However, one may choose to be a little bit different but the basics remain the same for everyone. Here we are going to discuss different case study sections. The purpose of every section in case study format is different from other and comprise of several unique key elements.

You may also study: How To Write a Case Study

It will definitely assist you to write your own case study with the utmost ease. The sections that are included in the case study are executive summary, introduction, analysis, alternatives and decision criteria, recommendations and implementation plan, conclusions and references, citing sources.

Before moving towards a detailed view of the case study format , let us have a look at the case study benefits.

Value of Case Study

Have you ever think why case studies are developed? This is the question you must ask yourself before writing your very first case study. Knowing the answers and keeping all that stuff in mind will let you write a successful and worth-reading case study.

It is the best way to put the students or learners in an active learning mode. Instead of just testing their memory, case study challenges the students to test their learning via practice, which is usually the easiest approach. In short, case studies proffer students a great opportunity to analyze and resolve the real-world problem with a practical approach. It makes the interpretation as well as problem-solving tasks easy for the learners.

A detailed look at the Case Study Format

Executive summary for a case study is usually similar to the general summary. It is basically a short snapshot that shed the image of your entire case precisely, which consists of a page, most of the time. It doesn’t include too much detail about your case but focuses on key elements or main highlights of your case study. Reading the executive summary of your case study must give the reader an idea about the entire case study and its key elements. There are two approaches adopted to write case studies.

• The first approach is to write the case study’s executive summary in short paragraphs.
• On the other hand, the second approach is to write it in form of points.

Key Points to Cover in an Executive Summary

There are a few things which are necessary to include in your case study’s executive summary i.e. problem statement, recommendation, evidence and supporting arguments, and last but not the least conclusion.

All these things comprise to form a perfect executive summary, which let the reader walk through the entire case study, just by reading it.

• The first thing to include in a case study format is an executive summary, as mentioned above. The very first thing to add in executive summary is problem statement. It let the reader know about the key issue discussed in the entire case in just a few lines. Problem statement usually comprises of one or two statement but may vary according to the case.
• The second thing to add is recommendation after stating the problem statement. What is this recommendation about? It presents one or a few ideas to resolve the problem stated in problem statement.
• The next thing to add in the executive summary is supporting arguments and evidence. It is all about highlighting key areas of your entire case and the arguments of the case. Moreover, it also states one or a few pieces of evidence that support your recommendation section.
• This is the last thing to add in the executive summary is conclusion that definitely concludes everything stated here in this portion. You must let the reader know the key message you want to deliver. Also, state why it is essential to resolve this problem and what are the expected outcomes if the reader follows your recommendations you stated in your case study.

The introduction section of the case study is somehow different from the introduction section of research paper . What is this section intended to have? It is usually here to formulate the stage for your entire case study. It must not only introduce the report of your case but also should state the key problem being faced and discussed thoroughly in a clear and accurate tone.

One thing which is worth-mentioning here is that case study is not like a scientific research report, which is only read by the experts or scientists. It must be written in such a way that a layperson could read and understand it well. Reading the introduction section of case study must let the user know about full case study i.e. what it is about, what are the key areas discussed in this and how the reader will get benefit from it etc. It must not be short enough to miss the necessary details. On the other hand, it must not be long enough that it becomes boring.

Don’t include irrelevant or unnecessary details in it. Just be precise and accurate, and try to include the following:

• A perfect and well-written introductory sentence.
• A short but precise problem statement.
• All necessary problem details.
• The best recommendations for the stated problem.
• And last but not the least: roadmap of the entire case study.

The next section of the case study, when it comes to case study format is analysis. It is usually a detailed section of your case study and it is supposed to examine the problem (which is identified in the previous section) in detail.

When it comes to the right way to structure the analysis section, make sure to ask from your instructor about this, whether there is any format to follow specifically when writing it i.e. SWOT or PEST etc? If your instructor tells you to write it generally, here are a few important things you need to know.

• Start with examining the problem and try to focus on its most crucial or sensitive parts. Here, you are not meant to include any irrelevant or unnecessary details. Your main focus should be the main problem and its critical areas.
• Make sure to mention the causes as well as effects, or any other detail you think is necessary to include. Also, make use of headings to highlight every single portion.
• Here, you are also meant to provide a meaningful conclusion to your analysis. It must conclude all the points, ideas and thoughts you discussed previously into some meaningful ending.

This section of the case study format addresses two key areas. The first one is alternatives and the second one is the decision criteria.

As the name suggests, alternatives must mention all the potential ways the identified problem can be addressed. It let the reader think about the different directions (which are successful as well) to solve the problem. Knowing all the alternatives or the available options to solve the problem, the reader can definitely identify the best possible solution to the problem, as per knowledge and thinking criteria.

One thing which is worth mentioning here is that all the presented solutions to the problems in the alternatives portion must be mutually exclusive. Why is it important to present the mutually exclusive alternatives? What are basically mutually exclusive alternatives?

Mutually exclusive alternatives refer to the situation in which selecting one alternative eliminate all others. There is a specific and a single solution to the identified problem. Mutually exclusive alternatives prevent a scenario in which it becomes essential to implement several available alternatives. When the alternatives will be mutually exclusive, it means that choosing one will eliminate the chances of selection of all others and thus, one alternative will be implemented.

The second thing which needs to be stated here in this portion is decision criteria. It means that you must state precisely your decisive factor i.e. key requirements one need to meet successfully for solving the problem. It is the most important thing here in this portion and you must state it in easy to read and simple words so that the reader could understand it well.

In this section of the case study format , the reader is well aware of all the recommendations for sure. So, there is no need to introduce the reader to the basics of the recommendations again. Rather, you are supposed to let the reader know the specifics of recommendation for solving the identified problem. In this regard, the reader will automatically get all the aspects of the recommended solution to the problem and will see how it will take you to the path of success i.e. towards the path of resolving the problem. For executing the recommendation in a successful manner, here you need to proffer the reader a well thought-out and a comprehensive implementation plan so that the reader could execute the recommended solution, making sure the success.

The recommendations and implementation plan is supposed to include a few things must, which are the following:

A detailed overview of what your recommendation entails, which are necessary steps to follow to implement this successfully and also, the required expertise or a list of equipment needed.

When it comes to the implementation plan, here are a few things which are essential to state here:

• The most important parts of the entire plan of implementation, and who will be accountable for those parts separately.
• Whether it is short term, long term or medium term implementation plan.
• The overall cost required to implement the recommendation.
• The effects of the implementation of recommendation on the entire organization.
• The last but not the least thing to mention here is the potential things which could fail while implementation and plan to recover that failure, if any.

This is the portion of your case study where you are going to make a final ending note for your reader in a few easy to understand yet powerful statements. These statements must emphasize the proposed recommendations. As per common observation, a few instructors don’t suggest you to include this portion of conclusion in your case study but it is helpful in providing a strong endnote to your case study.

There are a few things which are essential to add in this conclusion section, which are the following:

• If the purpose of your case is complex, make sure to summarize it here, in point form, so that the reader could have a review at the entire case again, before approaching the conclusion.
• If you haven’t yet stated the importance of your findings, make sure to do it here in this conclusion section.
• A few concluding sentences that shed the case’s summary and let the reader know what he has learned from this. Moreover, choose to finalize with a few memorable and impactful sentences.

However, the conclusion is the most important section of your case study as you are going to give your entire case an end note, so here are a few things you must keep in your mind while writing this portion.

• A few people give an abrupt ending to the case study, which is one of the biggest mistakes ever. The reason is that the ending must be impactful and must not leave the reader disappointed. So, formulate a few sentences to create a path towards a natural close.
• While stating your recommendation, try to summarize the ways problem will be resolved at hand.
• Make sure everything you write in conclusion portion is convincing enough to persuade the reader to believe that the recommended solution will work the best for solving the particular problem.

As per universal rule, you must cite any idea, though, or expression that is not yours and is presented by someone else. These citations are must to include at the end of your case study. The plagiarism policies or academic misconduct policies vary from one institute to another so you must familiarize yourself with the ones of your institute. Other than this, try your level best to make your case study written in a perfect manner and make sure to cite all of the following:

• Ideas presented by others, which are originally not by you.
• Use of quotations is not recommended while writing the case study. But, if you do, make sure to cite it properly.
• Any summarized work by any other writer.
• Definitions, models or theories etc presented by others must also be properly cited.
• Any information from company websites, annual reports, or press releases must also be cited in a proper manner.

What is the Proper Way to Write Citations?

If you are going to write the citation for the very first time, you need to know that these aren’t written generally. Rather, there is a specific format to follow while writing them. There are a few citations styles which are used by the students universally but before finalizing, you must ask your instructor to suggest you the best one.

A few most commonly used citation styles are the following:

An Ideal Case Study should be LOGICAL, ALL INCLUSIVE & THOROUGH

There are a few characteristics your case study must possess, which are the following:

The first and foremost thing is that each and every section or part of your case study must be logical. Any guesses or estimations must not be included in your case study as everything is supposed to be logical and authentic. However, you can choose to write your observation generally in your case study but it must not state any sort of assumptions made from that.

All INCLUSIVE

The next thing is that your case study must not miss any data or findings. It should be all inclusive i.e. you aren’t given the authority to choose data or findings to include or skip. You are liable to put everything in it. Otherwise, it could fail to be a successful case study.

The last thing to mention here is that your case study must be thorough. You aren’t just meant to write down all the observations during your research but rather, you must proffer the in-depth detail to every observation as well.

So, this is all about writing your case study as well as the right case study format to follow while writing it. Keep all the above-listed things in mind and start your writing process now.

Case study definition

Case study, a term which some of you may know from the "Case Study of Vanitas" anime and manga, is a thorough examination of a particular subject, such as a person, group, location, occasion, establishment, phenomena, etc. They are most frequently utilized in research of business, medicine, education and social behaviour. There are a different types of case studies that researchers might use:

• Collective case studies

• Descriptive case studies

• Explanatory case studies

• Exploratory case studies

• Instrumental case studies

• Intrinsic case studies

Case studies are usually much more sophisticated and professional than regular essays and courseworks, as they require a lot of verified data, are research-oriented and not necessarily designed to be read by the general public.

How to write a case study?

It very much depends on the topic of your case study, as a medical case study and a coffee business case study have completely different sources, outlines, target demographics, etc. But just for this example, let's outline a coffee roaster case study. Firstly, it's likely going to be a problem-solving case study, like most in the business and economics field are. Here are some tips for these types of case studies:

• Your case scenario should be precisely defined in terms of your unique assessment criteria.

• Determine the primary issues by analyzing the scenario. Think about how they connect to the main ideas and theories in your piece.

• Find and investigate any theories or methods that might be relevant to your case.

• Keep your audience in mind. Exactly who are your stakeholder(s)? If writing a case study on coffee roasters, it's probably gonna be suppliers, landlords, investors, customers, etc.

• Indicate the best solution(s) and how they should be implemented. Make sure your suggestions are grounded in pertinent theories and useful resources, as well as being realistic, practical, and attainable.

• Carefully proofread your case study. Keep in mind these four principles when editing: clarity, honesty, reality and relevance.

Badlapur sex abuse: Opposition claims BJP link to school. Here is the truth

The opposition has alleged that there was a delay in filing an fir in the badlapur sex abuse case as the school was run by people connected to the bjp..

Listen to Story

• Secretary of Badlapur school trust has links to BJP
• A banner shows Tushar Apte greeting Badlapur BJP MLA
• Two kindergarten students were sexually abused at Badlapur school

The opposition in Maharashtra has attempted to turn the heat on the government in the Badlapur case , alleging the BJP's links to the school where two kindergarten students were sexually assaulted. A fact-check by India Today found that Tushar Apte, secretary of the trust running the school, was linked to the BJP.

A banner posted by Tushar Apte on his Facebook page showed that he was the BJP president of the public welfare committee of Ambarnath. Another post said that his brother, Chetan Apte, was the city deputy president of Badlapur town.

Another banner on his social media account showed Tushar Apte greeting Badlapur BJP MLA Kisan Kathore. The president of the trust, Uday Kotwal, is also seen on another banner.

Former Maharashtra Chief Minister Uddhav Thackeray was the first to claim that the Badlapur school was run by people connected to the BJP. Thackeray demanded strict action against the culprits without looking at political connections.

The opposition has also alleged that there was a delay of 12 hours in filing an FIR in the incident as Apte was a BJP office bearer.

Congress leader Vijay Waddetiwar, Leader of the Opposition in Maharashtra, has also opposed the appointment of senior advocate Ujjwal Nikam as the special public prosecutor for the case.

The Congress has said that Nikam contested the 2024 Lok Sabha election on a BJP ticket and alleged that the school was also managed by individuals with ties to the BJP.

However, BJP leader Chitra Wagh said the school trust consisted of members of all parties. She said since 1965, when the school started, trust members change every five years. Published By: Abhishek De Published On: Aug 22, 2024

A disease which can kill cats, both domestic and wild, has been discovered for the first time in the US.

A variant of the rustrela virus -- related to the wider-known rubella virus which causes a skin rash in humans -- called RusV was discovered in a female mountain lion in Douglas County, Colorado last year, according to a study published in the journal, Emerging Infectious Diseases, this month.

The big cat was observed in May 2023 with lesions on her skin and signs of severe muscle weakness in her hind legs. She was also reluctant to get up and had decreased mobility.

Wildlife officers suspected that the mountain lion was suffering from a disease, but were unsure what wase causing her behavior. To end her suffering and prevent the destruction of brain tissue, the big cat was tranquilized and shot in the chest.

Then, the study authors started work to investigate the potential cause of the unknown disease.

The scientists said the study of tissue samples, the cat’s history, and genetic sequencing suggested that she was suffering from the rustrela virus variant, RusV. Also known as Rubivirus strelense , RusV is the cause of what is known as “staggering disease.”

Staggering disease is a usually fatal neurologic syndrome in cats, the study noted, and RusV was only recently identified as its cause. Animals show sign of lesions and the same limb impairment.

It’s been documented in domestic cats in Europe since the 1970s, and has also been found in rodents. A similar syndrome was reported in Alabama cats 45 years ago, but the cause was obscure.

To demonstrate a link between the lesions and RusV, researchers used previously-developed hybridization methods for the virus. Hybridization is the process in which two complementary, single-stranded DNA -- the hereditary material in humans and nearly all organisms -- or RNA (ribonucleic acid) molecules bond together. RNA is a nucleic acid in all living cells that has similarities to DNA.

Hybridization allows for the identification of specific genes and an analysis of levels of the molecule messenger RNA (mRNA) in cells. MRNA molecules carry the genetic information that is needed to produce proteins, which serve many key functions in the body like repairing cells and helping to protect the immune system.

The authors said these methods showed RusV RNA was in all regions of the big cat’s brain and nearly all levels of the spinal cord.

“We found particularly abundant or large, dot-like signals in the granule cell layer of the hippocampus, and in Purkinje cells of the cerebellum, similar to findings from staggering disease cases in cats from Europe,” said researchers at the Friedrich-Loeffler-Institute in Germany.

The novel RusV virus discovered in Colorado was compared with other strains. It revealed that the Colorado samples belonged to known genetic sequences in Europe.

Scientists don’t yet know how widespread the virus is in domestic cats or wild ones in the US.

The American Veterinary Medical Association said symptoms to watch for include a staggering gait , the inability to retract claws, extreme sensitivity to touch, tremors, and seizures. The illness usually lasts for a few days to a few weeks, but can also linger for more than a year.

It generally results in a decline that require the animal to be euthanized.

“We’re not worried if this is an isolated case,” Dr. Karen Fox, a wildlife pathologist at Colorado State University and study author, told National Geographic . “But traditionally, when we find diseases, it means you’re the tip of an iceberg, and there’s a bunch more you’ve missed over time.”

Integrating New Therapies in Clinical Practice

Nuara’s Experience

Nuara, who moderated a roundtable discussion in Scottsdale, Arizona, brought a unique perspective with his experience in treating adult patients with vitiligo. He shared the case of a 32-year-old professional makeup artist who was deeply concerned about her depigmented patches affecting her livelihood. “She came to us seeking treatment because she felt that her condition reflected on her professional skills,” Nuara explained.

Case Study: A Professional Makeup Artist’s Journey

Nuara discussed the initial steps in managing this patient’s condition, emphasizing the importance of understanding her unique concerns and goals. “As a professional makeup artist, her appearance was integral to her career. She felt that the depigmented patches on her hands and face could undermine her credibility with clients,” he said. This case highlights the profound impact vitiligo can have on patients’ professional and personal lives.

Prior to visiting Nuara, the patient had been treated with the topical calcineurin inhibitor tacrolimus and a class I steroid for 6 months. However, she experienced minimal improvement and started noticing skin thinning in periocular areas. “The patient was not satisfied with her results and was concerned about the visible skin thinning,” Nuara noted.

“One of the first steps we took was to conduct baseline labs to assess for comorbidities, such as thyroid disease and anemia,” said Nuara. “Her thyroid function tests, including thyroid-stimulating hormone, thyroxine, thyroid peroxidase, and complete blood count, were all normal.” To address her concerns, Nuara performed a comprehensive assessment, including baseline laboratory tests to check for comorbidities such as thyroid disease. “We conducted a thorough assessment to rule out any underlying conditions that could be contributing to her vitiligo. It’s important to consider the whole patient, not just the skin manifestations,” he emphasized.

Nuara developed a personalized treatment plan tailored to the patient’s needs and lifestyle. “Given her profession, we focused on treatments that would be effective yet minimally disruptive to her daily routine,” he explained. The treatment plan included a combination of topical corticosteroids and calcineurin inhibitors to manage inflammation and promote repigmentation.

In the roundtable discussion, the group considered the next steps for a patient who had failed initial topical treatments. “We discussed the use of phototherapy, specifically the excimer laser, as a viable next option,” said Nuara. The patient underwent excimer laser treatments twice a week for 3 to 4 months.

“We also incorporated narrowband UV-B phototherapy sessions, which have been shown to be effective for vitiligo. This required careful scheduling to accommodate her work commitments,” Nuara noted. The phototherapy sessions were initially set at 3 times a week, with frequency adjusted based on response.

Monitoring Progress and Making Adjustments

Regular follow-ups were essential to monitor the patient’s progress and adjust the treatment plan as needed. “We scheduled follow-ups every 3 months to assess her response to treatment and make any necessary adjustments,” Nuara said. This flexible approach ensured that the treatment remained effective and aligned with the patient’s evolving needs.

The patient also received ruxolitinib cream. “Ruxolitinib cream was introduced as part of her treatment plan due to its efficacy and tolerability, especially for sensitive areas like the face and hands,” Nuara explained. The cream was applied twice daily, and the patient was educated on its proper use to maximize benefits.

Connecting Patients to Support Groups

Nuara emphasized the importance of addressing the psychological and social aspects of vitiligo. “We provided resources for psychological support, including counseling services and support groups, to help her cope with the emotional impact of her condition,” he said. This holistic approach aimed to improve the patient’s overall well-being and quality of life.

He shared that the patient initially struggled with feelings of anxiety and self-consciousness. “She expressed concerns about how her clients and peers perceived her. We encouraged her to join a support group where she could connect with others facing similar challenges,” Nuara recounted. This support network played a crucial role in boosting her confidence and resilience.

Ongoing Management With Positive Outcomes

Over the course of her treatment, the patient experienced significant improvements in her vitiligo. “After 6 months of consistent treatment, we observed notable repigmentation in the affected areas, and her atopic dermatitis was well controlled,” Nuara reported. The patient was pleased with the results and felt more confident in her professional and personal life.

Nuara highlighted the importance of ongoing management and patient education. “We continued to monitor her progress and made adjustments to the treatment plan as needed. It’s important to educate patients about the chronic nature of vitiligo and the need for continuous care,” he advised.

The purpose of this study is to explore the effects of accumulated dust and weather conditions on the energy generated by solar photovoltaic panels in Ouargla, Algeria, between May 3 and August 3, 2023. For this experiment, two monocrystalline panels with a power output of 390 W manufactured by Zergoune Green Energy Company, as well as data-logging equipment, were used. The first panel was perfectly cleaned before starting every test and the second panel remained uncleaned. On day 90, the cleaned panel maintained an average power of 193 W, while the dusty panel exhibited a lower average power of 139 W. The greatest average reduction in efficiency, approximately 36.32%, occurred after 3 months of exposure to weather conditions. The scanning electron microscope (SEM) analysis demonstrates the existence of microscopic dust particles which prevent part of solar radiation away instead of being absorbed by the photovoltaic cells, leading to a drop in the efficiency of the PV module. The primary chemical elements found in dust are oxygen, silicon, aluminum, and magnesium.
