"How does one think evaluatively? It all begins with assumptions. Systematically articulating, examining, and testing assumptions is the foundation of evaluative thinking... This book, more than any other, explains how to build a strong foundation for effective interventions and useful evaluation by rigorously working with assumptions."
—Michael Quinn Patton, PhD. Author of Utilization-Focused Evaluation and co-editor of THOUGHTWORK: Thinking, Action, and the Fate of the World, USA.
"This updated edition presents us with a new opportunity to delve into both the theoretical and practical aspects of paradigmatic, prescriptive, and causal assumptions. We need to learn, and apply these insights with the deep attention they deserve."
—Zenda Ofir, PhD. Independent Evaluator, Richard von Weizsäcker Fellow, Robert Bosch Academy, Berlin, Germany. Honorary Professor, School of Public Leadership, Stellenbosch University, South Africa.
“This thought-provoking book explains why assumptions are an essential condition within the theories and methodologies of evaluation; and how assumptions influence the ways that evaluators approach their work...It will enrich the ways that evaluators develop their models, devise their methodologies, interpret their data, and interact with their stakeholders.”
