We begin with an overview of the history and evolution of case study research, followed by a discussion of the methodological and philosophical variations found within case study designs. We end with a summary of the common characteristics of case study research and a table that brings together the fundamental elements that we found common in all case study approaches to research.

Long-term Review and Clinical Implications. A case is selected because it is interesting in itself or can facilitate the understanding of something else; it is instrumental in providing insight on an issue STAKE, The research may also continue for an extended period of time, so processes and developments can be studied as they happen.

The researcher then writes up the information from both sources above as the case study, and interprets the information.

Like YINMERRIAMasserts that when information is plentiful and concepts abstract, it is important to utilize processes that help interpret, sort, and manage information and that adapt findings to convey clarity and applicability to the results. Case selection and structure[ edit ] An average, best resume writing service dc typical case, is often not the richest in information.

YIN's two-part definition focuses on the scope, process, and methodological characteristics of case study research, emphasizing the nature of inquiry as being empirical, and the importance of context to the case. Interaction between participants and the researcher is required to generate data, which is an indication of the researcher's level of connection to and being immersed in the field.

Case studies continued to be used during this time, however usually as a method within quantitative studies or referred to as descriptive research to study a specific phenomenon MERRIAM, He presented a business plan prada process for undertaking case study research where formal propositions or theories guide the research process and are tested as part of the outcome, highlighting his realist approach to qualitative case study research.

Examples are provided of how these researchers' philosophical orientation influences the application of case study in practice. Interaction with research subjects therefore needs to be minimized and subjectivity managed to avoid biasing the results ibid. Bounding the case is essential to focusing, framing, and managing data collection and analysis.

A case is selected because it is interesting in itself or can facilitate the understanding of something else; it is instrumental in providing insight on an issue STAKE, Case study designs have been used across a number of disciplines, particularly the social sciences, education, business, law, and health, to address a wide range of research questions.

Furthermore, postpositivists accept that everyone is inherently biased in why using case study approach, which ultimately influence how the methods used are deployed. These elements delineate case study from other forms of research and inform the critical aspects of the research design and execution.

Validity of research results are verified through the scrutiny of others and, as such, adherence to mechanisms that ensure rigor in data collection and analysis is vital. An interpretative position views reality as multiple and subjective, based on meanings and understanding. The subject is the "practical, historical unity" through which the theoretical focus of the study is being viewed.

Therefore, emphasis is placed on using multiple methods with triangulation to circumvent errors and understand what is happening in reality as close as possible to the "truth" LINCOLN et al.

Strengths of Case Studies

All the approaches mentioned here use preconceived categories in the analysis and they are ideographic in their approach, i. This mixed use of terminology is confusing given the definitional separations between methodology and methods and the varied application of case study in research endeavors.

Alternatively it may be chosen because of researchers' in-depth local knowledge; where researchers have this local knowledge they are in a position to "soak and poke" as Richard Fenno put it, [15] and thereby to offer reasoned lines of explanation based on this rich knowledge of setting and circumstances.

Pragmatic constructivist MERRIAM maintains a constructivist approach to case study research, whereby the researcher assumes that reality is constructed intersubjectively through meanings and understandings developed socially and experientially. How the methods are used will vary and depend on the research purpose and design, which is often a variation of a single or multiple case study research design.

Strengths of Case Studies Provides detailed rich qualitative information.

Even today case histories are one of the main methods of investigation in abnormal psychology and psychiatry.

Limitations of Case Studies

As the figure highlights, early case studies were conducted in the social sciences. This context led to a philosophical division in research approaches: They can help us generate new ideas that might be tested by other methods.

In terms of epistemology, STAKE argues that situation shapes activity, experience, and one's interpretation of the case. Critical instance case studies.
