Types Of Case Studies

Case studies come in various forms, each tailored to meet specific research goals and insights:

Problem-Solving Case Study

Designed to identify and tackle specific issues within a particular setting, such as an organization, community, or industry. 

This type is hands-on and practical, often used in business or healthcare contexts, where the objective is to diagnose a problem and develop strategies or solutions to address it. 

By examining real-world obstacles and devising actionable remedies, problem-solving case studies are valuable for organizations looking to overcome challenges and improve performance.

Descriptive Case Study

Focuses on providing an in-depth snapshot of a particular situation, phenomenon, or event. Rather than aiming to influence outcomes or solve a problem, they rigorously document what is happening within a set timeframe. 

Researchers gather observations and details to create a holistic picture, which can be helpful for further analysis or for those seeking to understand a topic without altering it. 

This approach is frequently used in social sciences, where it provides insights that help contextualize and explain real-world scenarios.

Collective Case Study

These involve examining several cases simultaneously or consecutively to discover patterns or similarities across them. 

By comparing multiple instances within a similar context, experimenters can draw generalizable conclusions and uncover shared factors that might not be visible in single-case studies. 

This type of study is particularly useful in fields like education and public health, where observing groups of related cases reveals trends and helps inform broader solutions or policies.

Explanatory Case Study

This study is used to investigate the causal mechanisms behind specific events or phenomena. Researchers dig into the "why" and "how" of an occurrence, exploring factors that influenced the outcome. 

By clarifying these cause-and-effect relationships, explanatory case studies provide insights that are essential for fields that require evidence-based reasoning, such as policy development or scientific research. 

This type is ideal for studying complex situations where understanding underlying reasons is crucial.

Exploratory Case Study

It is typically conducted to pave the way for more in-depth future research on a new or relatively unknown topic. They help define questions, establish priorities, and provide preliminary data that can serve as a foundation for further investigation. 

This type of study is often seen in emerging fields or novel research areas, allowing researchers to gain preliminary insights and determine the direction of more detailed studies.

Instrumental Case Study

In such a study, the case itself is not as important as the insights it provides into a larger issue. This approach uses a particular instance as a "tool" to understand broader phenomena, trends, or concepts. 

By examining a specific example, researchers can apply what they learn to a bigger picture, often informing theory or policy. 

Instrumental case studies are useful in fields like psychology, where a single case can offer valuable information about common human behaviors or societal trends.

Intrinsic Case Study

This type of study is conducted when researchers have a genuine interest in a particular case that stands out due to its unique characteristics. 

This study is less about applying findings to broader contexts and more about understanding the case itself, often for its uniqueness, rarity, or novelty. 

Intrinsic case studies are common in areas like medicine, where a rare medical case might be examined to gain specialized insights without aiming for generalizability.

Pros & Cons Of Case Studies

Case studies bring unique strengths and challenges to research, helping to uncover detailed concepts while posing certain limitations.

Useful Tips For Writing An Effective Case Study

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.

What Are the Types of Case Studies?

Case studies can be categorized into several types based on their focus and purpose. Here are some common types of case studies:

types of case studies

  • Collective Case Studies : These types of case studies involve investigating any group of individuals. Here, the researchers need to study a group of people in a specific setting or any community. Ex: Psychologists must explore how access to the resources in any society can affect people’s mental wellness.
  • Descriptive Case Studies: These involve starting with any descriptive theory. The subjects are then observed, and the gathered information is compared to the preexisting approaches.
  • Explanatory Case Studies: These types of case studies are primarily used to conduct any casual investigation. Here, the researchers are more interested in looking for the factors that caused specific results.
  • Exploratory Case Studies : These case studies are conducted when researchers want to explore a new or relatively unexplored topic. They are more open-ended and aim to generate hypotheses and ideas for further research.
  • Instrumental Case Studies : These case studies are selected because they provide insights into a broader issue or theory. The case is used as a means to investigate a more general phenomenon.
  • Intrinsic Case Studies : In these case studies, the case itself is of particular interest due to its uniqueness or rarity. The goal is not to generalize findings to a larger population but to understand the specific case deeply.
  • Pilot Case Studies : Pilot case studies are conducted as a preliminary investigation before launching a larger study. They help researchers refine their research questions, methods, and procedures.
  • Problem-Oriented Case Studies : These case studies focus on solving a specific problem or addressing a particular issue. Researchers aim to provide practical solutions based on their analysis of the case.
  • Ethnographic Case Studies : Ethnographic case studies involve immersing the researcher in the subject’s environment to gain an in-depth cultural understanding. This is often used in anthropology and sociology.
  • Longitudinal Case Studies : Longitudinal studies involve observing and analyzing a case over an extended period of time. This allows researchers to track changes, developments, and trends that occur over time.
  • Comparative Case Studies : Comparative case studies involve comparing two or more cases to draw similarities, differences, and patterns between them. This type of study is often used to test hypotheses or theories.
  • Critical Instance Case Studies : Critical instance cases are chosen because they represent a crucial or pivotal event that can provide insights into a larger issue or theory.

Each type of case study serves a different purpose and is designed to answer specific research questions. Researchers choose the type of case study that best aligns with their objectives and the nature of the phenomenon they are investigating.

What Are the Methods of a Case Study?

A   case study research   is a qualitative research design. It is often used in the social sciences since it involves observing the cases or subjects in their settings with the most minor interference from the researcher.

In the case study method, the researchers pose a definite question raging any individual or group for testing their hypotheses or theories. This is done by gathering data from the interviews with the essential data.

Case study research is a perfect way to understand the nuances of any matter often neglected in quantitative research methods. A case study is distinct from any other qualitative study in the following ways:

  • Focused on the effect of any set of circumstances in any group or any individual
  • It mostly begins with any specific question regarding one or more cases
  • It usually focuses on the individual accounts and its experiences

The primary features of case study research methods are as follows:

  • The case study methods   must involve the researcher asking a few questions of one person or a small group of people who are known as the respondents for testing the survey.
  • The case study in the research mythology might apply triangulation to collect data. It is then analyzed and interpreted to form a hypothesis to be tested through further research or validated by other researchers.
  • Concepts are defined using objective language with references to the Preconceived Notions. These individuals may have about them. A researcher sets out to discover by asking any specific question on how people think about their findings.
  • The case study method needs a clear concept and theory to guide the processes. A well-organized research question is fundamental while conducting any case study since its results depend on it. The best approach for answering the research questions is challenging the preexisting theories, assumptions or hypotheses.

Benefits and Limitations of Case Studies

The benefits of case studies are as follows:

  • Case studies give many details to be collected and will be easily obtained by the other research designs. The collected data is mostly richer than that can be funded via different experimental methods.
  • Case studies are primarily conducted on the rare cases where more extensive samples of similar participants are unavailable.
  • Scientific experiments can also be conducted within certain case studies.
  • The case studies can also help the experimenters adapt the ideas and produce novel hypotheses for later testing.

Disadvantages of Case Studies

  • One of the main criticisms in case studies is that the collected data cannot necessarily be generated for any broader population. This can lead to data being collected over any case study that is only sometimes relevant or useful.
  • Some of the case studies still need to be scientific. Many scientists used case studies for conducting several experiments, the results of which were only sometimes very successful.
  • Case studies are primarily based on one person, so only one experimenter can collect the data. This can lead to a bias in data collection that can influence the results in frequent designs.
  • Drawing any definite cause or effect from many case studies is sometimes challenging.

Importance of Case Study

  • A case study is a particular research h method involving an up-close and in-depth investigation of any subject, and it is related to a contextual position. These are produced by following a research form. The case study helps bring an understanding of any complex issue. This can extend experience or add strength to the already existing knowledge via the previous research. The contextual analysis revolves around a small number of events or situations.
  • Researchers have used case studies for an extended period, and they have been successfully applied in various disciplines like social sciences.

  • Look around on the home page. Does anything seem interesting to you?
  • How would you go about finding a place to eat near you in Downtown Oakland? You want something kind of quick, open late, not too expensive, and with a good rating.
  • What do the reviews say about the restaurant you've chosen?
  • What was the most important factor for you in choosing this spot?
  • You're currently close to the 19th St Bart station, and it's 9PM. How would you get to this restaurant? Do you think you'll be able to make it before closing time?
  • Your friend recommended you to check out a place called Belly while you're in Oakland. Try to find where it is, when it's open, and what kind of food options they have.
  • Now go to any restaurant's page and try to leave a review (don't actually submit it).

What was the worst thing about your experience?

It was hard to find the bart station. The collections not being able to be sorted was a bit of a bummer

What other aspects of the experience could be improved?

Feedback from the owners would be nice

What did you like about the website?

You're going on a vacation to Italy next month, and you want to learn some basic Italian for getting around while there. You decided to try Duolingo.

  • Please begin by downloading the app to your device.
  • Choose Italian and get started with the first lesson (stop once you reach the first question).
  • Now go all the way through the rest of the first lesson, describing your thoughts as you go.
  • Get your profile set up, then view your account page. What information and options are there? Do you feel that these are useful? Why or why not?
  • After a week in Italy, you're going to spend a few days in Austria. How would you take German lessons on Duolingo?
  • What other languages does the app offer? Do any of them interest you?

I felt like there could have been a little more of an instructional component to the lesson.

It would be cool if there were some feature that could allow two learners studying the same language to take lessons together. I imagine that their screens would be synced and they could go through lessons together and chat along the way.

Overall, the app was very intuitive to use and visually appealing. I also liked the option to connect with others.

Overall, the app seemed very helpful and easy to use. I feel like it makes learning a new language fun and almost like a game. It would be nice, however, if it contained more of an instructional portion.

What is a Case Study?

A case study is defined as an in-depth analysis of a particular subject, often a real-world situation, individual, group, or organization. 

It is a research method that involves the comprehensive examination of a specific instance to gain a better understanding of its complexities, dynamics, and context. 

Case studies are commonly used in various fields such as business, psychology, medicine, and education to explore and illustrate phenomena, theories, or practical applications.

In a typical case study, researchers collect and analyze a rich array of qualitative and/or quantitative data, including interviews, observations, documents, and other relevant sources. The goal is to provide a nuanced and holistic perspective on the subject under investigation.

The information gathered here is used to generate insights, draw conclusions, and often to inform broader theories or practices within the respective field.

Case studies offer a valuable method for researchers to explore real-world phenomena in their natural settings, providing an opportunity to delve deeply into the intricacies of a particular case. They are particularly useful when studying complex, multifaceted situations where various factors interact. 

Additionally, case studies can be instrumental in generating hypotheses, testing theories, and offering practical insights that can be applied to similar situations. Overall, the comprehensive nature of case studies makes them a powerful tool for gaining a thorough understanding of specific instances within the broader context of academic and professional inquiry.

Key Characteristics of Case Study

Case studies are characterized by several key features that distinguish them from other research methods. Here are some essential characteristics of case studies:

  • In-depth Exploration: Case studies involve a thorough and detailed examination of a specific case or instance. Researchers aim to explore the complexities and nuances of the subject under investigation, often using multiple data sources and methods to gather comprehensive information.
  • Contextual Analysis: Case studies emphasize the importance of understanding the context in which the case unfolds. Researchers seek to examine the unique circumstances, background, and environmental factors that contribute to the dynamics of the case. Contextual analysis is crucial for drawing meaningful conclusions and generalizing findings to similar situations.
  • Holistic Perspective: Rather than focusing on isolated variables, case studies take a holistic approach to studying a phenomenon. Researchers consider a wide range of factors and their interrelationships, aiming to capture the richness and complexity of the case. This holistic perspective helps in providing a more complete understanding of the subject.
  • Qualitative and/or Quantitative Data: Case studies can incorporate both qualitative and quantitative data, depending on the research question and objectives. Qualitative data often include interviews, observations, and document analysis, while quantitative data may involve statistical measures or numerical information. The combination of these data types enhances the depth and validity of the study.
  • Longitudinal or Retrospective Design: Case studies can be designed as longitudinal studies, where the researcher follows the case over an extended period, or retrospective studies, where the focus is on examining past events. This temporal dimension allows researchers to capture changes and developments within the case.
  • Unique and Unpredictable Nature: Each case study is unique, and the findings may not be easily generalized to other situations. The unpredictable nature of real-world cases adds a layer of authenticity to the study, making it an effective method for exploring complex and dynamic phenomena.
  • Theory Building or Testing: Case studies can serve different purposes, including theory building or theory testing. In some cases, researchers use case studies to develop new theories or refine existing ones. In others, they may test existing theories by applying them to real-world situations and assessing their explanatory power.

Understanding these key characteristics is essential for researchers and practitioners using case studies as a methodological approach, as it helps guide the design, implementation, and analysis of the study.

Key Components of a Case Study

A well-constructed case study typically consists of several key components that collectively provide a comprehensive understanding of the subject under investigation. Here are the key components of a case study:

  • Provide an overview of the context and background information relevant to the case. This may include the history, industry, or setting in which the case is situated.
  • Clearly state the purpose and objectives of the case study. Define what the study aims to achieve and the questions it seeks to answer.
  • Clearly identify the subject of the case study. This could be an individual, a group, an organization, or a specific event.
  • Define the boundaries and scope of the case study. Specify what aspects will be included and excluded from the investigation.
  • Provide a brief review of relevant theories or concepts that will guide the analysis. This helps place the case study within the broader theoretical context.
  • Summarize existing literature related to the subject, highlighting key findings and gaps in knowledge. This establishes the context for the current case study.
  • Describe the research design chosen for the case study (e.g., exploratory, explanatory, descriptive). Justify why this design is appropriate for the research objectives.
  • Specify the methods used to gather data, whether through interviews, observations, document analysis, surveys, or a combination of these. Detail the procedures followed to ensure data validity and reliability.
  • Explain the criteria for selecting the case and any sampling considerations. Discuss why the chosen case is representative or relevant to the research questions.
  • Describe how the collected data will be coded and categorized. Discuss the analytical framework or approach used to identify patterns, themes, or trends.
  • If multiple data sources or methods are used, explain how they complement each other to enhance the credibility and validity of the findings.
  • Present the key findings in a clear and organized manner. Use tables, charts, or quotes from participants to illustrate the results.
  • Interpret the results in the context of the research objectives and theoretical framework. Discuss any unexpected findings and their implications.
  • Provide a thorough interpretation of the results, connecting them to the research questions and relevant literature.
  • Acknowledge the limitations of the study, such as constraints in data collection, sample size, or generalizability.
  • Highlight the contributions of the case study to the existing body of knowledge and identify potential avenues for future research.
  • Summarize the key findings and their significance in relation to the research objectives.
  • Conclude with a concise summary of the case study, its implications, and potential practical applications.
  • Provide a complete list of all the sources cited in the case study, following a consistent citation style.
  • Include any additional materials or supplementary information, such as interview transcripts, survey instruments, or supporting documents.

By including these key components, a case study becomes a comprehensive and well-rounded exploration of a specific subject, offering valuable insights and contributing to the body of knowledge in the respective field.

Sampling in a Case Study Research

Sampling in case study research involves selecting a subset of cases or individuals from a larger population to study in depth. Unlike quantitative research where random sampling is often employed, case study sampling is typically purposeful and driven by the specific objectives of the study. Here are some key considerations for sampling in case study research:

  • Criterion Sampling: Cases are selected based on specific criteria relevant to the research questions. For example, if studying successful business strategies, cases may be selected based on their demonstrated success.
  • Maximum Variation Sampling: Cases are chosen to represent a broad range of variations related to key characteristics. This approach helps capture diversity within the sample.
  • Selecting Cases with Rich Information: Researchers aim to choose cases that are information-rich and provide insights into the phenomenon under investigation. These cases should offer a depth of detail and variation relevant to the research objectives.
  • Single Case vs. Multiple Cases: Decide whether the study will focus on a single case (single-case study) or multiple cases (multiple-case study). The choice depends on the research objectives, the complexity of the phenomenon, and the depth of understanding required.
  • Emergent Nature of Sampling: In some case studies, the sampling strategy may evolve as the study progresses. This is known as theoretical sampling, where new cases are selected based on emerging findings and theoretical insights from earlier analysis.
  • Data Saturation: Sampling may continue until data saturation is achieved, meaning that collecting additional cases or data does not yield new insights or information. Saturation indicates that the researcher has adequately explored the phenomenon.
  • Defining Case Boundaries: Clearly define the boundaries of the case to ensure consistency and avoid ambiguity. Consider what is included and excluded from the case study, and justify these decisions.
  • Practical Considerations: Assess the feasibility of accessing the selected cases. Consider factors such as availability, willingness to participate, and the practicality of data collection methods.
  • Informed Consent: Obtain informed consent from participants, ensuring that they understand the purpose of the study and the ways in which their information will be used. Protect the confidentiality and anonymity of participants as needed.
  • Pilot Testing the Sampling Strategy: Before conducting the full study, consider pilot testing the sampling strategy to identify potential challenges and refine the approach. This can help ensure the effectiveness of the sampling method.
  • Transparent Reporting: Clearly document the sampling process in the research methodology section. Provide a rationale for the chosen sampling strategy and discuss any adjustments made during the study.

Sampling in case study research is a critical step that influences the depth and richness of the study’s findings. By carefully selecting cases based on specific criteria and considering the unique characteristics of the phenomenon under investigation, researchers can enhance the relevance and validity of their case study.

Case Study Research Methods With Examples

  • Interviews:
  • Interviews involve engaging with participants to gather detailed information, opinions, and insights. In a case study, interviews are often semi-structured, allowing flexibility in questioning.
  • Example: A case study on workplace culture might involve conducting interviews with employees at different levels to understand their perceptions, experiences, and attitudes.
  • Observations:
  • Observations entail direct examination and recording of behavior, activities, or events in their natural setting. This method is valuable for understanding behaviors in context.
  • Example: A case study investigating customer interactions at a retail store may involve observing and documenting customer behavior, staff interactions, and overall dynamics.
  • Document Analysis:
  • Document analysis involves reviewing and interpreting written or recorded materials, such as reports, memos, emails, and other relevant documents.
  • Example: In a case study on organizational change, researchers may analyze internal documents, such as communication memos or strategic plans, to trace the evolution of the change process.
  • Surveys and Questionnaires:
  • Surveys and questionnaires collect structured data from a sample of participants. While less common in case studies, they can be used to supplement other methods.
  • Example: A case study on the impact of a health intervention might include a survey to gather quantitative data on participants’ health outcomes.
  • Focus Groups:
  • Focus groups involve a facilitated discussion among a group of participants to explore their perceptions, attitudes, and experiences.
  • Example: In a case study on community development, a focus group might be conducted with residents to discuss their views on recent initiatives and their impact.
  • Archival Research:
  • Archival research involves examining existing records, historical documents, or artifacts to gain insights into a particular phenomenon.
  • Example: A case study on the history of a landmark building may involve archival research, exploring construction records, historical photos, and maintenance logs.
  • Longitudinal Studies:
  • Longitudinal studies involve the collection of data over an extended period to observe changes and developments.
  • Example: A case study tracking the career progression of employees in a company may involve longitudinal interviews and document analysis over several years.
  • Cross-Case Analysis:
  • Cross-case analysis compares and contrasts multiple cases to identify patterns, similarities, and differences.
  • Example: A comparative case study of different educational institutions may involve analyzing common challenges and successful strategies across various cases.
  • Ethnography:
  • Ethnography involves immersive, in-depth exploration within a cultural or social setting to understand the behaviors and perspectives of participants.
  • Example: A case study using ethnographic methods might involve spending an extended period within a community to understand its social dynamics and cultural practices.
  • Experimental Designs (Rare):
  • While less common, experimental designs involve manipulating variables to observe their effects. In case studies, this might be applied in specific contexts.
  • Example: A case study exploring the impact of a new teaching method might involve implementing the method in one classroom while comparing it to a traditional method in another.

These case study research methods offer a versatile toolkit for researchers to investigate and gain insights into complex phenomena across various disciplines. The choice of methods depends on the research questions, the nature of the case, and the desired depth of understanding.
