A case study research dissertation is a qualitative research approach that thoroughly examines one particular topic or case.
In a Case study research, you will analyze complicated, real-life situations and thoroughly grasp the topic and its environment in the social sciences, education, business, and clinical research.
In this article, we will go through different types of case study and the advantages or limitations it holds.
Check out the following examples of case study research.
Case Study Research Example: Assessing the Impact of Digital Marketing in Generating High Customer Base of Online Retailers: Case Study of EBAY
Case Study Dissertation Example 2: The Impact of Technology in Improving Resilience and Sustainability in Construction Projects – Case of BIM and LCA
Unlike experimental research or survey research, which often aims to control or generalize findings, case study research emphasizes the importance of understanding the unique characteristics of the case.
What is a Case Study?
The data used in case study research is often gathered from various sources, including interviews, observations, documents, and artifacts. The process of gathering data is frequently iterative, with the researcher returning to the case as needed to gather more information.
In case study research, data analysis is also an iterative process involving the researcher repeatedly returning to the data to spot trends, themes, and insights.
Depending on the research topic and the case's characteristics, case study research can take many different shapes. Some case studies are exploratory, seeking to produce novel theories or hypotheses. Others are explicative and aim to validate or test preexisting notions. Others are purely descriptive, summarising the situation thoroughly without necessarily attempting to explain or extrapolate results.
Types of Case Study Research
Case study research can be classified into different types based on the number of cases studied, the length of time the study takes place, and the purpose of the study.
Single Case Study
This case study involves an in-depth analysis of an individual, group, organization, or event. Single case studies often explain a complex phenomenon, such as a rare medical condition, an unusual business strategy, or a unique organizational structure. The strength of a single case study lies in its ability to provide a rich, in-depth understanding of the case, but its findings cannot be easily generalized to other cases.
Multiple Case Study
Several similar situations are analyzed in this kind of case study. Multiple case study is frequently employed to find patterns or themes that appear in several examples and evaluate hypotheses that have been derived from a single case study. Although they can be time- and resource-intensive, multiple case studies allow for a more thorough knowledge of phenomena than single case studies.
Longitudinal Case Study
A single case is investigated over a long time, sometimes several years or decades. Longitudinal case studies are frequently utilized to follow changes in a phenomenon over time, such as shifts in a person's health state, the development of an organization, or the effects of social intervention. The advantage of longitudinal case studies is that they can give a thorough knowledge of a phenomenon's temporal dimension, but they demand a big time and financial commitment.
Comparative Case Study
The comparative case study is a research design that systematically investigates two or more cases to identify patterns of similarity and difference. By examining how multiple cases differ in particular aspects, researchers can better understand the underlying factors that influence the variations in a phenomenon across contexts. This methodology allows for rigorous testing of hypotheses about the causes and consequences of such differences.
However, it is essential to carefully select and match cases to ensure that they are comparable and representative of the phenomenon under investigation. The strength of comparative case studies lies in their ability to provide in-depth insights into complex and nuanced aspects of a phenomenon.
The type of case study research chosen depends on the research question, the purpose of the study, and the resources available. Each type of case study has its strengths and weaknesses, and researchers should choose the type that best fits their research goals.
Case Study Research Examples
Here we have summarized examples of case study research for you to understand case study research in a better way.
Example 1: Effects of Social Media on Teenage Mental Health.
In this case study, a researcher examined the experiences of a young woman who underwent gender transition in her early 20s. The study used interviews, observations, and a review of medical records to gain a deep understanding of the woman's journey. The findings revealed the complex emotional and social challenges faced by individuals undergoing gender transition and the importance of social support networks in facilitating the transition process.
Example 2: Impact of Leadership Style on Employee Satisfaction in a Healthcare Organization.
In this case study dissertation example, a researcher compared the leadership styles and practices of three different CEOs in the technology industry. The study used interviews with the CEOs and their colleagues and a review of company documents and financial data to gain insights into the factors contributing to effective leadership in this industry. The findings showed that while all three CEOs had different styles and approaches, they shared common qualities such as adaptability, strategic thinking, and a focus on innovation.

Advantages of Case Study Research
1. Provides Rich and Detailed Insights
Case study research allows for a thorough and comprehensive analysis of a single case, providing rich and detailed insights into the subject and its context. This method can help researchers gain a deeper understanding of complex and multifaceted issues that may be difficult to explore through other research methods.
2. Flexible and Adaptable
Employing case study research in various subjects and research environments is possible since it is a versatile and adaptable methodology. When selecting a case that relates to their research issue, researchers might modify their procedures and methods to meet the unique requirements of the case.
3. Allows for Triangulation of Data
Case study research typically entails gathering and scrutinizing diverse data sources, such as interviews, observations, and documents. This practice of triangulating data can enhance the accuracy and dependability of the conclusions drawn from the study.
4. Can be used to Generate New Theories
Theoretical innovations or improving preexisting theories may result from case study research. Researchers can discover new thoughts and ideas that need to be included in current theories or create new theories entirely by thoroughly examining a particular example.
Disadvantages of Case Study Research
1. Limited Generalizability
One of the main disadvantages of case study research is its limited generalizability. Since case study research focuses on a single case, the findings may not represent other cases or populations. It can limit the external validity of the findings.
2. Time-consuming and Resource-intensive
Case study research can be resource-intensive and time-consuming, requiring extensive data collection and analysis. Researchers may need to spend significant time in the field, conducting interviews and analyzing data.
3. Potential for Researcher Bias
Since case study research relies heavily on the researcher's interpretation and analysis of the data, there is a potential for researcher bias. It is important to acknowledge that researchers can carry implicit biases and preexisting assumptions that could potentially sway the analysis and affect the interpretation of findings.
4. Ethical Concerns
Case study research can raise ethical concerns, particularly when dealing with sensitive or personal information. Researchers must obtain informed consent from participants and protect their privacy and confidentiality.
Conclusion
In conclusion, case study research is a valuable qualitative method that provides rich and detailed insights into a single case. It allows for a thorough analysis of complex and multifaceted issues, is flexible and adaptable, and allows for data triangulation. However, case study research also has its limitations. Researchers should weigh the advantages and disadvantages of case study research and carefully consider whether it is an appropriate method for their research question and context.
