Exploratory Case Studies
An exploratory case study is a research method used to investigate a phenomenon or topic
in depth, often with limited prior knowledge or existing theories. It aims to explore and
understand a specific case or situation, generating new insights and hypotheses.
Key characteristics of exploratory case studies:
In-depth investigation: They involve a detailed examination of a particular case or
phenomenon.
Qualitative methods: Primarily rely on qualitative data collection techniques such as
interviews, observations, and document analysis.
Flexibility: The research design is often flexible and can be adapted as the study
progresses.
Theory building: Exploratory case studies can be used to generate new theories or refine
existing ones.
Hypothesis generation: They can help identify potential research questions and
hypotheses for future studies.
Common uses of exploratory case studies:
Exploring new phenomena: When little is known about a particular topic or issue.
Developing research questions: Identifying research questions that can be explored in
future studies.
Generating new theories: Building new theories based on empirical evidence.
Understanding complex social phenomena: Exploring the nuances and complexities of
social interactions and behaviors.
By conducting exploratory case studies, researchers can gain valuable insights into a wide range
of topics and contribute to the development of new knowledge and understanding.
An explanatory case study is a research method that aims to explain a particular
phenomenon or event. It involves in-depth investigation of a specific case to understand the
underlying causes, mechanisms, and processes.
Key characteristics of an explanatory case study:
Focus on causation: It seeks to explain why something happened or why a particular
outcome occurred.
Theoretical framework: It often draws on existing theories to guide the research and
interpret the findings.
Data collection: It involves a variety of data collection methods, such as interviews,
observations, and document analysis.
Data analysis: The data is analyzed to identify patterns, trends, and causal relationships.
Theory building and testing: Explanatory case studies can be used to test existing
theories or develop new ones.
In essence, an explanatory case study delves deeper than a descriptive case study, aiming to
uncover the "why" behind a particular phenomenon.
Would you like to know more about how to conduct an explanatory case study or explore some
examples?
Conducting an Explanatory Case Study
Key Steps:
1. Research Question Development: Clearly articulate the research question that the case
study will address.
2. Case Selection: Choose a case that is relevant to the research question and provides a
rich context for analysis.
3. Data Collection: Utilize a variety of methods, including interviews, observations,
document analysis, and surveys.
4. Data Analysis: Analyze the collected data to identify patterns, themes, and causal
relationships.
5. Theory Building and Testing: Develop or refine theories based on the findings of the
case study.
6. Interpretation and Conclusion: Interpret the findings in light of the research question
and draw conclusions about the phenomenon under investigation.
Example of an Explanatory Case Study:
Imagine a researcher wants to understand why some companies are more successful in
implementing sustainable practices than others. They could conduct an explanatory case study of
a specific company that has been particularly successful in this area. By examining the
company's history, culture, leadership, and decision-making processes, the researcher can
identify the key factors that contributed to its success.
Would you like to delve deeper into a specific aspect of explanatory case studies, such as
data analysis techniques or challenges in conducting such research?
A descriptive case study is an in-depth analysis of a specific phenomenon or event. It aims
to provide a detailed and comprehensive picture of the subject matter, without necessarily
seeking to explain causal relationships or draw broader generalizations.
Key characteristics of a descriptive case study:
Focus on detail: It provides a rich and detailed description of the case, including its
context, history, and current state.
Data collection: It relies on a variety of data collection methods, such as interviews,
observations, and document analysis.
Holistic perspective: It considers multiple aspects of the case, including social, cultural,
economic, and political factors.
Real-world context: It is grounded in real-world situations and provides insights into
practical applications.
Purpose of descriptive case studies:
Understanding complex phenomena: They can help researchers understand complex
phenomena that are difficult to study through quantitative methods.
Generating hypotheses: They can be used to generate new research questions and
hypotheses.
Providing rich descriptions: They can provide detailed descriptions of specific cases,
which can be useful for teaching and learning.
Developing theory: They can contribute to the development of new theories or the
refinement of existing ones.
In essence, a descriptive case study is a valuable tool for exploring and understanding the
nuances of a specific phenomenon or event
Single Case Study Format
A single case study is an in-depth examination of a specific case or phenomenon. It's a research
method often used in fields like psychology, education, and business.

Surveys: Use surveys to collect quantitative data from a larger group of people.
Remember: The specific format and content of a single case study will vary depending on the
research question and the nature of the case being studied. However, the general structure
outlined above provides a solid foundation for conducting a rigorous and informative case study.
Holistic Case Study Format
A holistic case study is a research method that examines a phenomenon in its entirety,
considering all relevant factors and their interrelationships. It aims to provide a comprehensive
understanding of the subject matter.
Here's a common format for a holistic case study:
1. Introduction:
oClearly state the research question or objective.
oProvide background information on the case and its relevance to the research
field.
oExplain the theoretical framework guiding the study.
oOutline the research methodology and data collection techniques.
2. Case Description:
oProvide a detailed description of the case, including its context, history, and
current state.
oUse rich, descriptive language to paint a vivid picture of the case.
oConsider multiple perspectives, such as those of individuals, groups, and
organizations involved.
3. Data Analysis:
oAnalyze the collected data using appropriate qualitative and quantitative methods.
oIdentify patterns, themes, and significant findings.
oInterpret the data in light of the theoretical framework.
4. Discussion and Interpretation:
oDiscuss the implications of the findings.
oCompare the findings to existing theories and research.
oIdentify limitations of the study and suggest areas for future research.
oExplore the broader theoretical and practical significance of the case study.
5. Conclusion:
oSummarize the key findings of the study.
oHighlight the contributions of the study to the field.
oDiscuss the limitations of the study and potential areas for further research.
oOffer recommendations based on the findings.
Key characteristics of a holistic case study:
In-depth analysis: It provides a detailed examination of a specific case or phenomenon.
Multiple perspectives: It considers multiple perspectives and factors influencing the
case.
Contextual understanding: It places the case within its broader context, including
historical, cultural, and social factors.
Rich description: It uses vivid language to describe the case, including quotes,
observations, and narratives.
Theoretical integration: It relates the findings to existing theories and develops new
theoretical insights.
By adopting a holistic approach, researchers can gain a deeper understanding of complex
phenomena and provide valuable insights for theory development and practical applications.
Embedded Case Study
An embedded case study is a research design that involves investigating multiple units of
analysis within a single overarching case. It's a powerful tool for exploring complex phenomena
in depth.
Key characteristics of an embedded case study:
Multiple units of analysis: The primary case is divided into smaller sub-units for more
focused investigation.
In-depth exploration: Each sub-unit is examined in detail, providing a rich and nuanced
understanding.
Interconnectedness: The sub-units are analyzed in relation to the overall case,
highlighting their interrelationships.
Flexibility: The design can be adapted to the specific research question and the
complexity of the case.
Example:
Consider a study on the implementation of a new educational reform in a school district. The
primary case could be the entire district, while the sub-units might be individual schools within
the district.
The primary case would examine the district-wide implementation of the reform.
The embedded cases would focus on specific schools, investigating how the reform was
implemented at the classroom level, the impact on student outcomes, and the challenges
and successes encountered.
By examining these sub-units, researchers can gain a deeper understanding of the factors
influencing the success or failure of the reform and identify best practices for future
implementation.
Benefits of Embedded Case Studies:
Richness of data: The combination of multiple units of analysis provides a more
comprehensive understanding of the phenomenon.
Increased generalizability: By studying multiple sub-units, researchers can identify
patterns and trends that may be applicable to other contexts.
Enhanced theoretical understanding: The detailed analysis of sub-units can contribute
to the development and refinement of theories.
Challenges of Embedded Case Studies:
Complexity: The design and analysis of embedded case studies can be complex and
time-consuming.
Data management: Managing and analyzing data from multiple sub-units can be
challenging.
Balancing breadth and depth: It's important to balance the need for breadth (examining
the overall case) with the need for depth (exploring the sub-units).
By carefully considering these factors, researchers can effectively utilize the embedded case
study design to conduct rigorous and insightful research.
Alternative Case Study Compositional Structures
While the linear-analytical structure is a common approach, there are other effective ways to
structure a case study:
1. Comparative Case Study Structure:
Multiple case studies: This involves comparing and contrasting two or more cases to
identify similarities and differences.
Theoretical lens: A theoretical framework is used to analyze the cases and draw
conclusions.
Cross-case analysis: Findings from individual cases are synthesized to develop broader
insights.
2. Chronological Case Study Structure:
Time-based narrative: The case is presented in chronological order, tracing its
development over time.
Key events and turning points: The focus is on significant events and their impact on the
case.
Evolutionary analysis: The study examines how the case has changed and evolved over
time.
3. Theoretical Case Study Structure:
Theory-driven approach: A specific theory is used to frame the case study.
Testing and refining theory: The case is used to test and refine the theory.
Theoretical implications: The findings are interpreted in light of the theory and
contribute to its development.
4. Multiple-Perspective Case Study Structure:
Diverse viewpoints: The case is examined from multiple perspectives, such as those of
different stakeholders.
Interdisciplinary approach: Insights from various disciplines are integrated to provide a
comprehensive understanding.
Complex social phenomena: This structure is particularly useful for studying complex
social phenomena that involve multiple actors and perspectives.
The choice of structure depends on the specific research question, the nature of the case, and the
desired outcomes. By understanding these alternative structures, researchers can select the most
appropriate approach to their study.
Sources and related content
The foundation of producing meaningful clinical research is asking a specific question that
addresses a gap in patient care. Yet, this first and crucial step is often rushed, leading to a
research question that is insufficiently refined or over-simplified.

It is one thing to identify broad areas of interest but further work is required to arrive at more
precise research questions. This involves a narrowing of focus. The brainstorming process that
has just been described can provide a step in this direction because it encourages the early
identification of relevant concepts and associated research methods. I have found venn and
hourglass diagrams to be useful in helping to structure thinking regarding the narrowing
process.

Venn diagrams involve the use of overlapping circles to show relationships among things and
they are used to help to represent visually the similarities and differences and relationships
between concepts. It is worth pointing out that many worthwhile research areas involve
relationships between tourism and other subjects and not tourism alone: thus, for example,
medical tourism involves links between medical matters and tourism; agritourism involves
relationships between agriculture and tourism; and so on. The possibilities are almost endless.
Thus, consideration of the relationships between tourism and other subjects can stimulate
thinking and such thinking can be structured through the use of venn diagrams.

However, the process involves more than this. At each step taken that narrows the focus, a
justification should be made of the option that is selected. In this way, the specific research
topic that is ultimately chosen is placed in a broader research context. Also, the process helps
the researcher to identify which literature is relevant to the research and to which study
domains a research contribution may be made (see comment below regarding discussion and
conclusions).

Its propositions, if any;
As for the second component, each proposition directs attention to something that should be
examined within the scope of study. For instance, assume that your research, on the topic of
interorganizational partnerships, began with the following question: How and why do
organizations collaborate with one another to provide joint services (e.g., a manufacturer and a
retail outlet collaborating to sell certain computer products)? These “how” and “why”
questions, capturing what you are really interested in addressing, led you to case study research
as the appropriate method in the first place. Nevertheless, these “how” and “why” questions
may not sufficiently point to what you should study.
Only if you are forced to state some propositions will you move in the right direction. For
instance, you might think that organizations collaborate because they derive mutual benefits.
This proposition, besides reflecting an important theoretical issue (that other incentives for
collaboration do not exist or are unimportant), also begins to tell you where to look for relevant
evidence (i.e., to define and ascertain the extent of specific benefits to each organization).
At the same time, exploratory studies may have a legitimate reason for not having any
propositions. Every exploration, however, should still have some purpose. Instead of
propositions, the design for an exploratory study should state this purpose, as well as the
criteria by which an exploration will be judged successful (or not). One successful outcome
might include the identification of the propositions to be examined in the later study. Consider
the analogy in BOX 5 for exploratory case studies. Can you imagine how you would ask for
support from Queen Isabella to do your exploratory study?
Its case(s);
This third component deals with your identifying the “case” to be studied—a problem that
rightfully confronts many researchers at the outset of their case studies (e.g., Ragin & Becker,
1992). You will need to consider at least two different steps: defining the case and bounding the
case.
In defining the case, the classic case studies usually focus on an individual person as the case
(e.g., Bromley, 1986, p. 1). Jennifer Platt (1992) has noted how the early case studies by scholars
in the Chicago school of sociology were life histories of such persons as juvenile delinquents or
derelict men. You also can imagine case studies of clinical patients (e.g., Brice, Wallace, & Brice,
2014; Johansen, Tavakoli, Bjelland, & Lumley, 2017), exemplary students (e.g., Jett, Curry, &
Vernon-Jackson, 2016; Schmitt & Goebel, 2015), teachers (e.g., Parsons, 2012), or different
leaders. In each situation, an individual person is the case being studied. Information about the
relevant individual would be collected, and several such individuals or “cases” might be included
in a multiple-case study.
You would still need study questions and study propositions to help identify the relevant
information to be collected about this individual or individuals. Without such questions and
propositions, you might be tempted to cover “everything” about the individual(s), which is
impossible to do. For example, the propositions in studying these individuals might be limited to
the influence of early childhood or the role of peer relationships. Such seemingly general topics
nevertheless represent a vast narrowing of the relevant scope and subsequent need for data.
The more a case study contains specific questions and propositions, the more it will stay within
feasible limits.
Of course, the “case” also can be some event or entity other than a single person. Case studies
have been done about a broad variety of topics, including small groups such as families (e.g.,
Kindell, Sage, Wilkinson, & Keady, 2014), citizen participation (e.g., Frieling, Lindenberg, &
Stokman, 2014; Wang & Breyer, 2012), communities, decisions, programs (e.g., Gavaravarapu &
Pavarala, 2014), nonprofit organizations (e.g., Kohl-Arenas, 2016), organizational learning (e.g.,
Ohemeng & Owusu, 2015), schools (e.g., Dimartino & Jessen, 2016), and events such as social
movements (e.g., Vos & Wagenaar, 2014) and disaster recovery efforts (e.g., Chung, 2017;
Downey, 2016). Feagin et al. (1991) also contains some classic examples of these single-cases in
sociology and political science.
To reduce the confusion and ambiguity in defining your case, one recommended practice is to
discuss your potential case selection with a colleague. Try to explain to that person what
questions you are trying to address and why you have chosen a specific case or group of cases
as a way of addressing those questions. This may help you to avoid incorrectly identifying your
case.
Once you have defined your case, other clarifications—sometimes called bounding the case—
become important. For instance, if the case is a small group, the persons to be included within
the group (they will become the immediate topic of your case study) must be distinguished
from those who are outside of it (they will become part of the context for your case study).
Similarly, if the case is about the local services in a specific geographic area, you need to decide
which services to cover. Also desirable, for almost any topic that might be chosen, are the
specific time boundaries to define the estimated beginning and ending of the case, for the
purposes of your study (i.e., whether to include the entire or only some part of the life cycle of
the entity that will become the case). Bounding the case in these ways will help to determine
the scope of your data collection and, in particular, how you will distinguish data about the
subject of your case study (the “phenomenon”) from data external to the case (the “context”).
The bounding also should tighten the connection between your case and your research
questions and propositions.
“The insider researcher may be seeking a methodological position that enables them to
integrate researcher and practitioner functions” (2011, p. 43). Some see this approach as
limited but others note its contributions to scholarship and to the real world (Shaw and
Faulkner, 2006). The benefits include accessibility to information and participants and the ability
to develop relevant knowledge that overcomes the academic–practitioner divide. However,
such studies are unavoidably affected by a connection to colleges, by ideological investments in
them, and by the lack of generalizability of the findings (Drake and Heath, 2011). We triangulate
methods to strengthen our interpretation of the findings (Stake, 2010). The aim was to focus on
“activities and contexts that provide an opportunity to understand an interesting part of how
things work” (Stake, 2010, p. 57), while offering more objective information based on the
quantitative data.

collaborative processes: The case of personal social services in israel. The International Journal
of Public Sector Management, 34(3), 336-355. https://doi.org/10.1108/IJPSM-03-2020-0064
The logic linking the data to the propositions; and
The fourth component has been increasingly better developed in doing case study research. The
component foreshadows the data analysis steps in your case study. Chapter 5 covers these steps
and the various analytic techniques and choices in detail. However, during the design stage, you
need to be aware of the choices and how they might suit your case study. In this way, your
research design can create a more solid foundation for the later analysis.
All the analytic techniques in Chapter 5 represent ways of linking data to propositions: pattern
matching, explanation building, time-series analysis, logic models, and cross-case synthesis. The
actual analyses will require that you combine or assemble your case study data as a direct
reflection of your study propositions. For instance, knowing that some or all of your
propositions cover a temporal sequence would mean that you might eventually use some type
of time-series analysis. If you note this strong likelihood during the design phase, you might
make sure that your planned data collection includes the collection of appropriate time markers
as part of the case being studied.
As a caution, if you have had limited experience in conducting empirical studies, at the design
stage you may not easily identify the likely analytic technique(s) or anticipate the needed data
to use the techniques to their full advantage. Even more experienced researchers may find that
they have either (a) collected too much data that was not later used in any analysis, or (b)
collected too little data that prevented the proper use of a desired analytic technique.
Sometimes, the latter situation may force researchers to return to their data collection phase (if
they can), to supplement the original data. The more you can avoid either of these situations,
the better off you will be.
The criteria for interpreting the findings.
For other research methods, a common illustration of this fifth component arises when
statistical analyses are relevant. For instance, by convention, quantitative studies consider a p
level of less than .05 to demonstrate that observed differences are “statistically significant” and
therefore associated with more robust findings. In other words, the statistical benchmarks serve
as the criteria for interpreting the findings. However, much case study analysis will not rely on
statistics, leading to the need to find other ways of thinking about such criteria.
When doing case study research, a major and important alternative strategy is to identify and
address rival explanations for your findings. Addressing such rivals becomes a criterion for
interpreting the strength of your findings: The more rivals that have been addressed and
rejected, the stronger will be your findings. Again, Chapter 5 discusses this strategy and how it
works. At the design stage of your work, the challenge is to anticipate and enumerate the
potentially important rivals. You will then want to include data about them as part of your data
collection. If you think of rival explanations only after data collection has been completed, your
thinking will help to justify and design a future study, but you will not be helping to complete
your current case study. For this reason, specifying important rival explanations is a part of a
case study’s research design work.
A case study approach was chosen for this research because it allows “complex social
phenomena” to be processed as they naturally occurred (Yin, 1994). This approach can target an
individual or a group and involve a variety of data sources such as life histories, documents, oral
histories interviews and participant observations (Berg, 2001). Case study methodology can be
either exploratory, descriptive or explanatory. This is an exploratory case study in that the field
notes were taken prior to defining the research question, positioning it as research that sets the
stage for a future more comprehensive study (Yin, 1994; Berg, 2001). Implications for future
studies, as motivated by the findings of this research, will be discussed later. According to Berg
(2001), exploratory case studies although the research questions can be later defined, must be
based upon an organizational structure prior to the beginning of the research. For this study,
the Project ESTEEM faculty, in addition to facilitating the daily activities with the students in the
afterschool program, conducted the homework sessions at the end of the day. All of the
conversations with the parents occurred at the end of the day when they arrived to pick up
their children. The researchers, as participant observers were actively involved in the research
setting, taking notes on their participation and also recording field notes of events and
interactions that occurred. Emerson, Fretz and Shaw (1995) assert that there is no assumed
correct way to write field notes because the process is more than reporting accounts of what
was heard and seen. Observations invite the interpretations of the observer. Even writing about
the same event could result in varied descriptions of the event. This is an important factor to
consider since there are different accounts and versions of accounts provided by the
researchers. In that vein, for this analysis every researcher’s account was considered the whole
story, rather than three distinct versions with facts that could be dismissed or debated. All
versions were used to confirm, disconfirm and provide support through the analyses. This was a
necessary strategy, considering some observations were unique to each observer. For example,
only one of the researchers noticed that Elaine, one of the parents whose story is represented
in this study, seemed to shy away from one of the earlier mathematics homework tutoring
sessions with her daughter. This notation, not observed by everyone, related to what was later
realized about Elaine having a mathematics phobia that challenged her ability to support her
daughter’s homework.

I am aware that most young scholars have been required to take courses on research methods.
However, I believe that few have received instruction in how to find a research topic or how to
narrow it into a manageable research question. Yet, in the absence of a clear and fairly precise
research direction, which is fundamental to the resolution of many subsequent research-related
issues, the contents of research methods courses are frequently less helpful than they might be.
Such classes are frequently disliked by their student participants because, in the absence of a
research topic of their own, their relevance may be unclear. They would be more helpful if this
challenge were expressed explicitly and direction provided.
Research should not start with the preparation of a research proposal. Rather, this is an
important intermediate step in the research journey. A strong proposal can only be crafted after
some research has been done, and the writer is aware of what previous research has been
undertaken. This needs to be known to place the proposed initiative in context and to justify its
likely value.
Broad topics need to be refined to identify research questions with a narrower focus. The
application of venn and hourglass diagrams can assist in the narrowing process in ways that will
help to justify critical decisions on research content while ensuring the maintenance of sound
contexts for the research.
It is suggested that assisting students to select a research topic and to identify research
questions is one of the most important tasks of a supervisor, and that it should precede
specification of research methods and data analysis. The writing and revising of concise
summaries can be a useful intermediate task in the research process. Finally, enthusiasm and
respect, and timely and thoughtful commentary, can have enduring effects that, though
seemingly small at the time, can have lasting influence on the success of a young scholar.
Case studies can be used to educate and advance demanding reasoning skills. Case studies can
