Determining how the collected evidence will support the research claims.
Yin identifies five critical components that must be determined at the outset to ensure research quality: Case study research : design and methods
Concepts derived from existing literature that guide the study's focus (optional for exploratory cases). Determining how the collected evidence will support the
Yin distinguishes between single-case designs (used for unique or extreme cases) and multiple-case designs , which follow a "replication logic" to strengthen generalizability. Typically "how" or "why" questions that explore contemporary
Typically "how" or "why" questions that explore contemporary phenomena within their real-life context.
Yin emphasizes that data analysis is often the most difficult stage and requires a clear strategy, such as pattern matching or explanation building. For the final report, he suggests several structures, including linear-analytic, comparative, chronological, and theory-building formats. 3rd Edition (2003) 5th Edition (2014) 6th Edition (2017) Primary Focus Establishing the method's rigor.
