At its best, case study provides the most vivid, the most inspirational, analysis that inquiry can offer. Einstein did it; Newton did it. Sociologists do it; psychologists do it. Doctors do it; teachers do it; lawyers do it; nurses do it. It is done across the disciplinary and methodological spectrum … Case study provides a form of inquiry that elevates a view of life in its complexity … It’s the realization that complexity in social affairs is frequently indivisible that has led to case study’s status as one of the most popular and most fertile design frames open to the researcher.
