The Sixth Edition of Robert K. Yin's bestseller provides a complete portal to the world of case study research. Offering comprehensive coverage of the design and use of the case study method in addition to an integration of applications, the book gives readers access to exemplary case studies drawn from a wide variety of academic and applied fields. The integration of applications will enable users to see more directly how concrete case studies can implement the principles of case study research methods. ? NEW TO THIS EDITION: Includes 11 in-depth applications that show how researchers have implemented case study methods successfully. Increases reference to relativist and constructivist approaches to case study research, as well as how case studies can be part of mixed methods projects. Places greater emphasis on using plausible rival explanations to bolster case study quality. Discusses synthesizing findings across case studies in a multiple-case study in more detail. Adds an expanded list of 15 fields that have text or texts devoted to case study research. Sharpens discussion of distinguishing research from non-research case studies. The author brings to light at least three remaining gaps to be filled in the future: how rival explanations can become more routinely integrated into all case study research; the difference between case-based and variable-based approaches to designing and analyzing case studies; and the relationship between case study research and qualitative research. KEY FEATURES: Numerous conceptual exercises, illustrative exhibits, vignettes, and a glossary make the book eminently accessible. Boxes throughout offer more in-depth real-world examples of research. Short, sidebar tips help succinctly explain concepts and allow students to check their understanding. Exercises throughout offer students the chance to immediately apply their knowledge.
