The research may also continue for an extended period of time, so processes and developments can be studied as they happen. These elements delineate case study from other forms of research and inform the critical aspects of the research design and execution. 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. Eisenhardt 's methodological work. The integration of formal, statistical, and narrative methods in a single study, combined with the use of empirical methods for case selection and causal inference, demonstrated the versatility of case study design and made a significant contribution to its methodological evolution ibid. Only someone qualified to diagnose and treat a person can conduct a formal case study relating to atypical i. Selection of cases is based on the purpose of the research and related to the theoretical propositions about the topic of interest.
Researchers who have contributed to the development of case study research come from diverse disciplines and their philosophical underpinnings have created variety and diversity in approaches used. YIN suggests careful screening in the selection of cases to ensure specific relevance to the issues of interest and the use of replication logic: cases are chosen to produce anticipated contrasting findings theoretical replication or similar findings literal replication.
Only someone qualified to diagnose and treat a person can conduct a formal case study relating to atypical i. Reality may be an objective thing, but it is understood and interpreted by people who, in turn, act upon it, and so critical realismwhich addresses the connection between the natural and social worlds, is a useful basis for analyzing the environment of and events within an organization.
A good case study should always make clear which information is the factual description and which is an inference or the opinion of the researcher. Selection of cases is based on the purpose of the research and related to the theoretical propositions about the topic of interest.

A case selection that is based on representativeness will seldom be able to produce these kinds of insights. Processes such as descriptive, thematic and content analysis, and triangulation are significant in ensuring the quality of a study, therefore, methods of data collection and analysis need to be organized and systematized with a detailed chain of evidence MERRIAM, The dominance of research using experimental designs continued through the s and s with quantitative empirical results considered to be gold standard evidence. A good case study should always make clear which information is the factual description and which is an inference or the opinion of the researcher. Gary Thomas thus proposes a typology for the case study wherein purposes are first identified evaluative or exploratory , then approaches are delineated theory-testing, theory-building or illustrative , then processes are decided upon, with a principal choice being between whether the study is to be single or multiple, and choices also about whether the study is to be retrospective, snapshot or diachronic, and whether it is nested, parallel or sequential. These are primarily descriptive studies. Because of this, constructivism and interpretivism commonly permeate the implementation of this research design. The idea behind these studies is that the collection of past studies will allow for greater generalization without additional cost or time being expended on new, possibly repetitive studies.
Teaching case studies have been a highly popular pedagogical format in many fields ranging from business education to science education. By Saul McLeodupdated What is a case study research method? Over the last 50 years, case study has been re-established as a credible, valid research design that facilitates the exploration of complex issues.
Common Characteristics of Case Study Research Despite variation in the approaches of the different exponents of case study, there are characteristics common to all of them.
