Multiple case study

A multiple case study is a research method that uses multiple research sites to gain a more comprehensive understanding of a particular phenomenon. It examines multiple cases in order to analyze patterns and the relationships between variables. This type of research method is used in management to gain a deeper understanding of a particular problem or issue. It is a systematic approach to gathering and analyzing data from multiple different sources such as individuals, organizations, or communities. The multiple case study approach allows researchers to gain greater insight into complex problems by considering a variety of perspectives, contexts, and sources of information.

Example of multiple case study

• A multiple case study example could be a study of different companies in the same industry in order to analyze the differences in their strategies and performance. For instance, a researcher may examine three companies in the automotive industry and determine what strategies have been successful and which have not. They may then compare the results of these three companies in order to determine which strategies are most effective.
• Another example of a multiple case study could be an examination of how different countries have responded to the COVID-19 pandemic. In this case, the researcher could look at different strategies adopted by countries worldwide and analyze the results of those strategies. They could then compare the results in order to determine which strategies have been most successful in mitigating the spread of the virus.
• A third example could be a study of different schools and how they have adapted to the online learning environment. The researcher could look at the successes and failures of different schools in order to determine which strategies are most effective in transitioning to remote learning. They could then use these findings to suggest changes and improvements to the schools’ policies and procedures.

When to use multiple case study

A multiple case study approach is a useful tool for researchers looking to gain a deeper understanding of complex issues. This method can be used in a variety of contexts, such as studying organizational management, social phenomena, or public health interventions. It can provide a more comprehensive understanding of the problem by considering a variety of perspectives, contexts, and sources of information. Examples of when multiple case studies can be used include:

• Examining the effectiveness of a particular policy or program in multiple contexts.
• Exploring the dynamics of organizational change across different settings.
• Investigating the impact of a cultural or social phenomenon on different communities.
• Analyzing the differences in responses to a public health intervention between populations.
• Understanding the dynamics of an issue in order to inform the development of new policies or practices.

Types of multiple case study

• Exploratory multiple case study: An exploratory multiple case study is used to explore a research problem in greater detail. It is used when the research question or problem is not well-defined, or when the researcher is uncertain about the best approach to study the problem. This type of multiple case study is often used to generate new ideas and to identify potential research topics.
• Explanatory Multiple Case Study: An explanatory multiple case study is used to explain a research problem in detail. It is used when the researcher is looking to explain the cause of an event or phenomenon. This type of multiple case study is used to identify patterns and relationships between variables, and to identify potential explanations for the phenomenon being studied.
• Descriptive Multiple Case Study: A descriptive multiple case study is used to describe a research problem in detail. It is used when the researcher wants to provide a comprehensive overview of a particular topic or phenomenon. This type of multiple case study is useful for providing a detailed description of a particular event or phenomenon and its context.
• Comparative Multiple Case Study: A comparative multiple case study is used to compare two or more research sites. It is used when the researcher wants to compare and contrast a phenomenon across multiple sites. This type of multiple case study is useful for examining similarities and differences between different research sites.
• Embedded Multiple Case Study: An embedded multiple case study is used to embed a single case study within a larger research project. It is used when the researcher wants to incorporate a single case study within a larger research project. This type of multiple case study is useful for exploring the complexities of a particular research problem, and for providing an in-depth understanding of a particular phenomenon.

Steps of multiple case study

A multiple case study is a research method that uses multiple research sites to gain a more comprehensive understanding of a particular phenomenon. The multiple case study approach allows researchers to gain greater insight into complex problems by considering a variety of perspectives, contexts, and sources of information. The following steps are necessary for conducting a successful multiple case study:

• Selecting the research sites: The first step in a multiple case study is to select the research sites. This requires careful consideration of factors such as the size and scope of the problem, the availability of data and resources, and the accessibility of the research sites.
• Gathering data: After selecting the research sites, the next step is to gather data. This can be done through interviews, surveys, focus groups, and other data collection methods.
• Analyzing the data: Once the data has been gathered, it must be analyzed in order to identify patterns and relationships between variables. This requires careful analysis of the data and may involve using statistical methods such as regression and factor analysis.
• Drawing conclusions: After the data has been analyzed, the next step is to draw conclusions. This involves synthesizing the data and making sense of it in order to answer the research question.
• Reporting the results: The final step is to report the results of the multiple case study. This can be done through a written report, a presentation, or a multimedia format.

Limitations of multiple case study

Multiple case studies have some limitations that should be taken into consideration when using this method. These limitations include:

• The multiple case study approach can be time consuming and resource intensive, as researchers must collect and analyze data from multiple different sources.
• It can be difficult to identify patterns and relationships between variables when studying multiple cases.
• The data collected from multiple cases may be difficult to generalize to a larger population.
• The multiple case study approach is limited to studying phenomena in limited contexts, and does not provide a holistic picture of a phenomenon.
• It can be difficult to control for all variables in a multiple case study, which can lead to inaccurate results.

Other approaches related to multiple case study

A multiple case study is a research method that uses multiple research sites to gain a more comprehensive understanding of a particular phenomenon. Other approaches related to multiple case studies include:

• Qualitative research: Qualitative research is an empirical research approach which focuses on understanding the perspectives, experiences, and beliefs of people in their contexts. It typically involves interviews, observations, and other forms of data collection.
• Grounded Theory: Grounded theory is an inductive research method that examines how social processes are created, maintained, and changed. It involves the systematic collection and analysis of data to generate new theory.
• Action Research: Action research is a type of research that involves the active participation of stakeholders in the research process. It focuses on identifying and resolving practical problems in an organization or community.
