What are the five typologies of case studies? Define each. What will be an ideal ...

1. Snapshot case studies: Detailed objective studies of one research entity at one point in time. Hypothesis testing by comparing patterns across subentities.
2. Longitudinal case studies: Quantitative and/or qualitative studies of one research entity at multiple time points.
3. Prepost case studies: Studies of one research entity at two time points separated by a critical event. A critical event is one that on the basis of a theory under study would be expected to impact case observations significantly.
4. Patchwork case studies: A set of multiple case studies of the same research entity, using snapshot, longitudinal, and/or prepost designs. This multi-design approach is intended to provide a more holistic view of the dynamics of the research subject.
5. Comparative case studies: A set of multiple case studies of multiple research entities for the purpose of cross-unit comparison. Both qualitative and quantitative comparisons are generally made.

Study questions: Questions are directed toward how and why considerations. This is the first task of the researcher, to define the questions asked.
 Study propositions or theoretical framework: The study's propositions derive from these how and why questions, and assist in developing a theoretical focus.
 Identification of the unit(s) of analysis: The unit of analysis defines what the case study is focusing on (what the case is), such as an individual, a group, an organization, a community, and so forth.
 The logical linking of the data to the propositions (or theory)
 The criteria for interpreting findings
 The last two characteristics are typically the least developed of all aspects in case studies.
