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.
