This practical guide helps readers understand and use the steps that program planners and evaluators take in implementing and monitoring a new program, policy, or practice in an organizational setting. The book covers the entire process, from planning, to carrying out the plan, and summarizing, reporting, and using the results. A wide range of real-world examples in the book are drawn from health, education, non-profit organizations, and public administration, and an extended case study, Your Turn boxes, and worksheet templates help readers apply concepts to their own projects. Ideal for practitioners, researchers, and students, this book can be used as a primary text for a process evaluation or an implementation monitoring course or as a supplemental text in a broader program evaluation course.
