What is a multi-case study?
 is a type of case study research that involves selecting and analyzing two or more cases that
share some common characteristics or features, but also differ in some aspects.
 The main goal of a multi-case study is to compare and contrast the cases, and identify the
similarities and differences among them, as well as the patterns and themes that emerge from
the cross-case analysis.

A multi-case study can also help to strengthen the validity and generalizability of the findings,
by demonstrating how the phenomenon of interest varies or remains consistent across different
contexts, settings, or situations.
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.
What are the advantages of using multiple cases?
 One of the main advantages of using multiple cases in a single study is that it allows the researcher
to explore the complexity and richness of the phenomenon under investigation, and to capture
its multiple dimensions, perspectives, and facets.
 enable the researcher to understand the differences and similarities of information
 multiple cases can enhance the credibility and reliability of the research, by providing more
evidence and data to support the findings, and by allowing the researcher to test and refine the
hypotheses or theories that guide the study.
 multiple cases can increase the transferability and applicability of the research, by showing
how the findings can be relevant and useful for different audiences, contexts, or scenarios.
What are the disadvantages of using multiple cases?
 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.
How to design and conduct a multi-case study?
 Designing and conducting a multi-case study requires a tailored approach to the specific
research question, purpose, and context.
The following steps are necessary for conducting a successful multiple case study:
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
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.
What are some examples of multi-case studies?
 Sadik (2008) conducted a multi-case study that looked at how teachers use digital storytelling to
foster students' literacy skills in four different elementary schools.
 Mair and Marti (2006) explored how social entrepreneurs create value and impact in six different
social enterprises in India.
 Reid et al. (2010) investigated how community-based organizations respond to climate change in
four African countries.
 Epstein and Hamric (2009) analyzed how health professionals cope with moral distress in three
intensive care units in Canada.
 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.
