Is a case study a legitimate research method?
Multiple Case Study
What is a case?
What constitutes a Case Study?
Research Design / Methodology
"No particular moment when data collection begins"
Data collection methods; observation, interviews, document review
Methodology: the most flexible (fluid)
Researchers need, through experience & reflection, to identify the best forms of analysis
A case is "an integrated system" with "boundaries"
Data collection: solely qualitative sources
4 strategies for triangulation; data source triangulation, investigator triangulation, theory triangulation, methodological triangulation
"There are multiple perspectives of a case"
Conduct data collection & analysis simultaneously
"A bounded system""an object rather than a process"
Validity & Reliability are irrelevant.
Recommends 2-3 research questions
Research Questions to guide the study
step-by-step guidelines for analytic techniques & procedures
"rich, thick description of the phenomenon under study
There are multiple interpretations of reality"
Data collection: mainly qualitative sources
A case is a thing, a single entity, a unit around which there are boundaries"
Detailed outline of Research Design; guidelines for literature review, theoretical framework(s), research problem, purposive sampling
INTERVIEWGood questions to ask, questions to avoid, probes, interview guide
Data collection methods; interview, observations, document analysis
Methodology: well-defined and well-structured
Case Study Design: flexible
Validity & Reliability are irrelevant
6 sources of evidence:documentation, archival records, interviews, direct observations, participant observation, phiysical artifacts
Link between RQs, theoretical frameworks & data collection
Design Quality:construct validity, internal validity, external validity, reliability
Data collection:Source TriangulationMultiple sources of evidence(Both qualitative & quantitative sources)
"How" and "Why" questions in relation to the phenomenon under study
Validity & Reliability: Triangulation in every phase of the research process. Chains of evidence, member checking
Methodology: very tight, well-structured, and detailed
Case Study Design comes before Data collection (prescriptive)
"objective truth" about the case
A case is a "contemporary phenomenon within its real life context"
No guidelines for literature review
