"Responding to evaluator and instructor demand, this book presents a diverse set of high-quality developmental evaluation (DE) case studies. Twelve insightful exemplars illustrate how DE is used to evaluate innovative initiatives in complex, dynamic environments, including a range of fields and international settings. Written by leading practitioners, chapters offer a rare window into what it takes to do DE, what roles must be fulfilled, and what results can be expected. Each case opens with an incisive introduction by the editors. The book also addresses frequently asked questions about DE, synthesizes key themes and lessons learned from the exemplars, and identifies eight essential principles of DE.
