Book excerpt: Michael Quinn Patton’s Facilitating Evaluation: Principles in Practice is the first book of its kind to explain in depth and detail how to facilitate evaluation processes with stakeholders. Using the author’s own stories of his experiences as an evaluation facilitator, the book illustrates the five evaluation facilitation principles that are the organizing framework for addressing how to work with stakeholders to generate evaluation questions, make decisions among methods, interpret findings, and participate in all aspects of evaluation. Ultimately, this book will help readers perform facilitation to enhance the relevance, credibility, meaningfulness, and utility of evaluations. "A must-read for anyone considering a high-impact evaluation!" –Margaret Lombe, Boston College
