What is the Case Study Method?
Simply put, the case method is a discussion of real-life situations that business executives have faced.
On average, you'll attend three to four different classes a day, for a total of about six hours of class time (schedules vary). To prepare, you'll work through problems with your peers.
How the Case Method Creates Value
Often, executives are surprised to discover that the objective of the case study is not to reach consensus, but to understand how different people use the same information to arrive at diverse conclusions. When you begin to understand the context, you can appreciate the reasons why those decisions were made. You can prepare for case discussions in several ways.
Case Discussion Preparation Details
In self-reflection.
The time you spend here is deeply introspective. You're not only working with case materials and assignments, but also taking on the role of the case protagonist—the person who's supposed to make those tough decisions. How would you react in those situations? We put people in a variety of contexts, and they start by addressing that specific problem.
In a small group setting
The discussion group is a critical component of the HBS experience. You're working in close quarters with a group of seven or eight very accomplished peers in diverse functions, industries, and geographies. Because they bring unique experience to play you begin to see that there are many different ways to wrestle with a problem—and that’s very enriching.
In the classroom
The faculty guides you in examining and resolving the issues—but the beauty here is that they don't provide you with the answers. You're interacting in the classroom with other executives—debating the issue, presenting new viewpoints, countering positions, and building on one another's ideas. And that leads to the next stage of learning.
Beyond the classroom
Once you leave the classroom, the learning continues and amplifies as you get to know people in different settings—over meals, at social gatherings, in the fitness center, or as you are walking to class. You begin to distill the takeaways that you want to bring back and apply in your organization to ensure that the decisions you make will create more value for your firm.
How Cases Unfold In the Classroom
Pioneered by HBS faculty, the case method puts you in the role of the chief decision maker as you explore the challenges facing leading companies across the globe. Learning to think fast on your feet with limited information sharpens your analytical skills and empowers you to make critical decisions in real time.
To get the most out of each case, it's important to read and reflect, and then meet with your discussion group to share your insights. You and your peers will explore the underlying issues, compare alternatives, and suggest various ways of resolving the problem.
How to Prepare for Case Discussions
There's more than one way to prepare for a case discussion, but these general guidelines can help you develop a method that works for you.
Preparation Guidelines
Read the professor's assignment or discussion questions.
The assignment and discussion questions help you focus on the key aspects of the case. Ask yourself: What are the most important issues being raised?
Read the first few paragraphs and then skim the case
Each case begins with a text description followed by exhibits. Ask yourself: What is the case generally about, and what information do I need to analyze?
Reread the case, underline text, and make margin notes
Put yourself in the shoes of the case protagonist, and own that person's problems. Ask yourself: What basic problem is this executive trying to resolve?
Note the key problems on a pad of paper and go through the case again
Sort out relevant considerations and do the quantitative or qualitative analysis. Ask yourself: What recommendations should I make based on my case data analysis?
Case Study Best Practices
The key to being an active listener and participant in case discussions—and to getting the most out of the learning experience—is thorough individual preparation.
We've set aside formal time for you to discuss the case with your group. These sessions will help you to become more confident about sharing your views in the classroom discussion.
Participate
Actively express your views and challenge others. Don't be afraid to share related "war stories" that will heighten the relevance and enrich the discussion.
If the content doesn't seem to relate to your business, don't tune out. You can learn a lot about marketing insurance from a case on marketing razor blades!
Actively apply what you're learning to your own specific management situations, both past and future. This will magnify the relevance to your business.
People with diverse backgrounds, experiences, skills, and styles will take away different things. Be sure to note what resonates with you, not your peers.
Being exposed to so many different approaches to a given situation will put you in a better position to enhance your management style.

II. Types of Case Studies
Let’s learn about the different types of case studies that help researchers choose the appropriate method to gain deep insights into their subject.
A. Explanatory Case Studies
Explanatory case studies are designed to explore cause-and-effect relationships. They aim to explain how and why certain events occur and what factors influence these outcomes. This type of case study is often used in social sciences, business, and policy research to test theories and develop new insights. For example, an explanatory case study might investigate how a specific business strategy led to increased market share or how a new policy affected public health outcomes. By focusing on detailed and comprehensive analysis, explanatory case studies help researchers define case study contexts and understand complex phenomena.
B. Exploratory Case Studies
Exploratory case studies are used to explore a topic or issue when there are no clear outcomes or established theories. They serve as a preliminary step that can help to identify research questions and hypotheses for further study. This type of case study is particularly useful when the subject matter is new or not well understood. For instance, researchers might conduct an exploratory case study to investigate the impact of emerging technologies on consumer behavior. Exploratory case studies are flexible and open-ended, allowing researchers to gather rich, qualitative data that can guide future research directions.
C. Descriptive Case Studies
Descriptive case studies provide a detailed account of a specific subject, event, or phenomenon. They aim to describe the context, characteristics, and outcomes without necessarily investigating causal relationships. This type of case study is useful for documenting and understanding the particulars of a situation. For example, a descriptive case study might provide an in-depth look at a company's organizational structure and culture. By offering a comprehensive overview, descriptive case studies help to illustrate and contextualize complex issues, making them easier to understand and analyze.
D. Multiple-Case Studies
Multiple-case studies, also known as comparative case studies, involve the analysis of several cases to understand similarities and differences. This type of case study allows researchers to compare and contrast different instances of a phenomenon, which can lead to more robust and generalizable findings. For example, a multiple-case study might examine several companies that have implemented similar business strategies to identify common factors that contribute to success. By analyzing multiple cases, researchers can draw broader conclusions and develop more nuanced insights.
E. Intrinsic Case Studies
Intrinsic case studies focus on a specific case because it is unique or interesting in its own right. The primary aim is to gain a deeper understanding of the case itself, rather than to generalize findings to other contexts. This type of case study is often used when the case has particular significance or offers unique insights. For example, an intrinsic case study might investigate a rare medical condition to understand its characteristics and implications. By delving deeply into the specifics of the case, intrinsic case studies provide valuable, detailed knowledge that can inform practice and theory.
F. Instrumental Case Studies
Instrumental case studies use a specific case to gain insights into a broader issue or to refine a theoretical concept. The case itself is of secondary interest; it serves as a means to understand something else. For example, a researcher might use an instrumental case study of a particular organization to explore general principles of organizational behavior. This type of case study is useful for developing and testing theories, as it allows researchers to apply and examine theoretical frameworks in real-world contexts.
G. Collective Case Studies
Collective case studies, also known as multiple-case studies, involve studying a group of cases simultaneously or sequentially. This approach aims to investigate a phenomenon, population, or general condition by analyzing multiple instances. Collective case studies are valuable for identifying patterns and trends across different cases. For instance, a collective case study might examine several educational programs across different schools to understand common factors that contribute to student success. By studying multiple cases, researchers can enhance the reliability and validity of their findings and develop a more comprehensive understanding of the topic.
Each type of case study offers unique advantages and serves different research purposes. Whether researchers aim to explain causal relationships, explore new topics, provide detailed descriptions, compare multiple instances, or gain insights into broader issues, case studies are versatile tools that can be tailored to fit various research needs. Using tools like case study templates and following a structured case study format can help ensure that the research is thorough and well-organized.

What is it?
Case study is a research methodology, typically seen in social and life sciences. There is no one definition of case study research. 1 However, very simply… ‘a case study can be defined as an intensive study about a person, a group of people or a unit, which is aimed to generalize over several units’. 1 A case study has also been described as an intensive, systematic investigation of a single individual, group, community or some other unit in which the researcher examines in-depth data relating to several variables. 2
Often there are several similar cases to consider such as educational or social service programmes that are delivered from a number of locations. Although similar, they are complex and have unique features. In these circumstances, the evaluation of several, similar cases will provide a better answer to a research question than if only one case is examined, hence the multiple-case study. Stake asserts that the cases are grouped and viewed as one entity, called the quintain . 6 ‘We study what is similar and different about the cases to understand the quintain better’. 6
The steps when using case study methodology are the same as for other types of research. 6 The first step is defining the single case or identifying a group of similar cases that can then be incorporated into a multiple-case study. A search to determine what is known about the case(s) is typically conducted. This may include a review of the literature, grey literature, media, reports and more, which serves to establish a basic understanding of the cases and informs the development of research questions. Data in case studies are often, but not exclusively, qualitative in nature. In multiple-case studies, analysis within cases and across cases is conducted. Themes arise from the analyses and assertions about the cases as a whole, or the quintain, emerge. 6
Benefits and limitations of case studies
If a researcher wants to study a specific phenomenon arising from a particular entity, then a single-case study is warranted and will allow for a in-depth understanding of the single phenomenon and, as discussed above, would involve collecting several different types of data. This is illustrated in example 1 below.
Using a multiple-case research study allows for a more in-depth understanding of the cases as a unit, through comparison of similarities and differences of the individual cases embedded within the quintain. Evidence arising from multiple-case studies is often stronger and more reliable than from single-case research. Multiple-case studies allow for more comprehensive exploration of research questions and theory development. 6
Despite the advantages of case studies, there are limitations. The sheer volume of data is difficult to organise and data analysis and integration strategies need to be carefully thought through. There is also sometimes a temptation to veer away from the research focus. 2 Reporting of findings from multiple-case research studies is also challenging at times, 1 particularly in relation to the word limits for some journal papers.
Examples of case studies
Example 1: nurses’ paediatric pain management practices.
One of the authors of this paper (AT) has used a case study approach to explore nurses’ paediatric pain management practices. This involved collecting several datasets:
Observational data to gain a picture about actual pain management practices.
Questionnaire data about nurses’ knowledge about paediatric pain management practices and how well they felt they managed pain in children.
Questionnaire data about how critical nurses perceived pain management tasks to be.
These datasets were analysed separately and then compared 7–9 and demonstrated that nurses’ level of theoretical did not impact on the quality of their pain management practices. 7 Nor did individual nurse’s perceptions of how critical a task was effect the likelihood of them carrying out this task in practice. 8 There was also a difference in self-reported and observed practices 9 ; actual (observed) practices did not confirm to best practice guidelines, whereas self-reported practices tended to.
Example 2: quality of care for complex patients at Nurse Practitioner-Led Clinics (NPLCs)
The other author of this paper (RH) has conducted a multiple-case study to determine the quality of care for patients with complex clinical presentations in NPLCs in Ontario, Canada. 10 Five NPLCs served as individual cases that, together, represented the quatrain. Three types of data were collected including:
Review of documentation related to the NPLC model (media, annual reports, research articles, grey literature and regulatory legislation).
Interviews with nurse practitioners (NPs) practising at the five NPLCs to determine their perceptions of the impact of the NPLC model on the quality of care provided to patients with multimorbidity.
Chart audits conducted at the five NPLCs to determine the extent to which evidence-based guidelines were followed for patients with diabetes and at least one other chronic condition.
The three sources of data collected from the five NPLCs were analysed and themes arose related to the quality of care for complex patients at NPLCs. The multiple-case study confirmed that nurse practitioners are the primary care providers at the NPLCs, and this positively impacts the quality of care for patients with multimorbidity. Healthcare policy, such as lack of an increase in salary for NPs for 10 years, has resulted in issues in recruitment and retention of NPs at NPLCs. This, along with insufficient resources in the communities where NPLCs are located and high patient vulnerability at NPLCs, have a negative impact on the quality of care. 10
These examples illustrate how collecting data about a single case or multiple cases helps us to better understand the phenomenon in question. Case study methodology serves to provide a framework for evaluation and analysis of complex issues. It shines a light on the holistic nature of nursing practice and offers a perspective that informs improved patient care.

A Quick Guide to Case Study with Examples
Published by Alvin Nicolas at August 14th, 2021 , Revised On August 29, 2023
A case study is a documented history and detailed analysis of a situation concerning organisations, industries, and markets.
A case study:
- Focuses on discovering new facts of the situation under observation.
- Includes data collection from multiple sources over time.
- Widely used in social sciences to study the underlying information, organisation, community, or event.
- It does not provide any solution to the problem .
When to Use Case Study?
You can use a case study in your research when:
- The focus of your study is to find answers to how and why questions .
- You don’t have enough time to conduct extensive research; case studies are convenient for completing your project successfully.
- You want to analyse real-world problems in-depth, then you can use the method of the case study.
You can consider a single case to gain in-depth knowledge about the subject, or you can choose multiple cases to know about various aspects of your research problem .
What are the Aims of the Case Study?
- The case study aims at identifying weak areas that can be improved.
- This method is often used for idiographic research (focuses on individual cases or events).
- Another aim of the case study is nomothetic research (aims to discover new theories through data analysis of multiple cases).
Types of Case Studies
There are different types of case studies that can be categorised based on the purpose of the investigation.

How to Conduct a Case Study?
- Select the Case to Investigate
- Formulate the Research Question
- Review of Literature
- Choose the Precise Case to Use in your Study
- Select Data Collection and Analysis Techniques
- Collect the Data
- Analyse the Data
- Prepare the Report
Step1: Select the Case to Investigate
The first step is to select a case to conduct your investigation. You should remember the following points.
- Make sure that you perform the study in the available timeframe.
- There should not be too much information available about the organisation.
- You should be able to get access to the organisation.
- There should be enough information available about the subject to conduct further research.
Step2: Formulate the Research Question
It’s necessary to formulate a research question to proceed with your case study. Most of the research questions begin with how, why, what, or what can .
You can also use a research statement instead of a research question to conduct your research which can be conditional or non-conditional.
Step 3: Review of Literature
Once you formulate your research statement or question, you need to extensively review the documentation about the existing discoveries related to your research question or statement.
Step 4: Choose the Precise Case to Use in your Study
You need to select a specific case or multiple cases related to your research. It would help if you treated each case individually while using multiple cases. The outcomes of each case can be used as contributors to the outcomes of the entire study. You can select the following cases.
- Representing various geographic regions
- Cases with various size parameters
- Explaining the existing theories or assumptions
- Leading to discoveries
- Providing a base for future research.
Step 5: Select Data Collection and Analysis Techniques
You can choose both qualitative or quantitative approaches for collecting the data . You can use interviews , surveys , artifacts, documentation, newspapers, and photographs, etc. To avoid biased observation, you can triangulate your research to provide different views of your case. Even if you are focusing on a single case, you need to observe various case angles. It would help if you constructed validity, internal and external validity, as well as reliability.
Example: Identifying the impacts of contaminated water on people’s health and the factors responsible for it. You need to gather the data using qualitative and quantitative approaches to understand the case in such cases.
Construct validity: You should select the most suitable measurement tool for your research.
Internal validity: You should use various methodological tools to triangulate the data. Try different methods to study the same hypothesis.
External validity: You need to effectively apply the data beyond the case’s circumstances to more general issues.
Reliability: You need to be confident enough to formulate the new direction for future studies based on your findings.

Step 6: Collect the Data
Beware of the following when collecting data:
- Information should be gathered systematically, and the collected evidence from various sources should contribute to your research objectives.
- Don’t collect your data randomly.
- Recheck your research questions to avoid mistakes.
- You should save the collected data in any popular format for clear understanding.
- While making any changes to collecting information, make sure to record the changes in a document.
- You should maintain a case diary and note your opinions and thoughts evolved throughout the study.
Step 7: Analyse the Data
The research data identifies the relationship between the objects of study and the research questions or statements. You need to reconfirm the collected information and tabulate it correctly for better understanding.
Step 8: Prepare the Report
It’s essential to prepare a report for your case study. You can write your case study in the form of a scientific paper or thesis discussing its detail with supporting evidence.
A case study can be represented by incorporating quotations, stories, anecdotes, interview transcripts , etc., with empirical data in the result section.
You can also write it in narrative styles using textual analysis or discourse analysis . Your report should also include evidence from published literature, and you can put it in the discussion section.
Advantages and Disadvantages of Case Study
Frequently asked questions, what is the case study.
A case study is a research method where a specific instance, event, or situation is deeply examined to gain insights into real-world complexities. It involves detailed analysis of context, data, and variables to understand patterns, causes, and effects, often used in various disciplines for in-depth exploration.
