Core Principles of Yin’s Case Study Research
Yin’s methodology rests on several foundational principles that guide researchers through the process of conducting rigorous case studies.
1. Clear Case Definition
A well-defined case is crucial for focused research. Whether studying a single case or multiple cases, clarity regarding what constitutes the case ensures the research remains targeted and coherent.
2. Use of Multiple Data Sources
Yin advocates for data triangulation, which involves collecting information from various sources such as interviews, observations, documents, and archival records to enhance validity.
3. Protocol Development
Developing detailed case study protocols ensures consistency and reliability. Protocols include research questions, data collection procedures, and analysis strategies.
4. Chain of Evidence
Maintaining a clear chain of evidence allows others to follow the research process, increasing transparency and credibility.
5. Addressing Bias
Researchers must be vigilant about biases, employing strategies like triangulation and peer review to mitigate subjective influences.

Types of Case Studies According to Yin
Yin categorizes case studies based on the purpose and scope of research.
1. Exploratory Case Study
Used to explore a phenomenon or issue where little prior research exists. It helps establish research questions and hypotheses.
2. Descriptive Case Study
Provides a detailed, comprehensive description of a phenomenon within its real-life context.
3. Explanatory Case Study
Focuses on understanding causal relationships and mechanisms behind observed phenomena.
4. Multiple-Case Study (Comparative)
Involves studying multiple cases to compare and contrast findings, enhancing generalizability.
