This book is organised around a seven-step model developed by the authors, and which has been tested and refined in workshops that cater to a broad spectrum of evaluation practitioners. Vignettes from practice and case studies, representing evaluations from a variety of geographic regions and sectors, demonstrate adaptive possibilities for small projects with budgets of a few thousand dollars or timelines as brief as a few days, to large-scale, long-term evaluations with multi-million-dollar budgets. The text is designed to incorporate quantitative, qualitative, and mixed-method designs.
