Case Study



Creswell (1998) defines a case study as an exploration of a “bounded system” or a case (or multiple cases) over time through detailed, in-depth data collection involving multiple sources of information rich in context.  Some consider “the case” as an object of study (e.g., Stake, 1995) while others consider it a methodology (e.g., Merriam, 1998).  According to Creswell, the bounded system is bounded by time and place, and it is the case being studied – a program, an event, an activity, or individuals. 


Procedures Involved In Conducting A Study:

·         ·        The researcher needs to situate the case in a context or setting.  The setting may be a physical, social, historical, and/or economic. 

·         ·        The researcher needs to identify the focus of the study.  It could be either on the case (intrinsic study), because of its uniqueness, or it may be on an issue or issues (instrumental study), with the case used instrumentally to illustrate the issue.  A case study could involve more than one case (collective case study). 

·         ·        In choosing what case to study, a researcher may choose a case because it shows different perspectives on the problem, process, or event of interest, or it may be just an ordinary case, accessible, or unusual.

·         ·        The data collection is extensive, drawing on multiple sources of information such as observations, interviews, documents, and audio-visual materials.

·         ·        The data analysis can be either a holistic analysis of the entire case or an embedded analysis of a specific aspect of the case. 

·         ·        From the data collection, a detailed description of the case is done.  Themes or issues are formulated and then the researcher makes an interpretation or assertions about the case. 

·         ·        When multiple cases are chosen, a typical format is to provide a detailed description of each case and themes within the case (called within-case analysis), followed by a thematic analysis across the cases (called a cross-case analysis), as well as assertions or an interpretation of the meaning of the case. 

·         ·        In the final stage, the researcher reports the “lessons learned” from the case (Lincoln and Guba, 1985).



·         ·        The researcher needs to identify his/her case among a host of possible candidates.

·         ·        The researcher needs to decide whether to study a single case or multiple cases.  The motivation for considering many cases is the issue of generalizability, which is not so much of a pressing issue in qualitative inquiry.  Studying more than one case runs the risk of a diluted study, lacking the “depth” compared to a single case.  “How many” cases becomes a challenge then.

·         ·        Getting enough information to get a good depth for the case is a challenge.

·         ·        Deciding on the boundaries in terms of time, events and processes may be challenging.  Some cases have no clean beginning and ending points.
