Case Study Research (Yin)
Overview
Case study research is an empirical inquiry that investigates a contemporary phenomenon in depth and within its real-life context, especially when the boundaries between phenomenon and context are not clearly evident. Yin's framework provides systematic design choices — single vs. multiple cases, holistic vs. embedded analysis — and emphasizes triangulation to strengthen construct validity.
When to Use
- Research questions are "how" or "why" questions about contemporary events
- The researcher has little or no control over behavioral events
- Contextual conditions are highly pertinent to the phenomenon of study
- Boundaries between phenomenon and context are blurred
When NOT to Use
- When frequency or incidence data is needed (use survey or experiment)
- When context is irrelevant and can be controlled (use experiment)
- When the goal is statistical generalization to a population
