'In the face of rapid, unpredictable change and diverse implementation contexts, we need more and better case studies to understand complex phenomena and to use that understanding for better policies, programs and initiatives in other places and times. Evidence about 'what works' on average in randomised controlled trials cannot be simply generalised to other contexts. But too often case studies are not done systematically or carefully. This important volume provides practical, well-informed guidance from leading writers and researchers on how to plan, implement and communicate case studies which can effectively answer questions about those cases and what these mean for planning initiatives in other places in the future. This book should become an essential guide and reference for everyone serious about quality evidence to inform public policy and practice.' Patricia Rogers, founder of BetterEvaluation
