Over the past decade Appreciative Inquiry (AI) has rapidly emerged as one of the most significant advances in the field of organization development and change. This book is the first to provide a comprehensive practitioner's guide to the AI Summit-the preferred method when applying whole-scale change to large groups. The authors-four of the leading experts on Appreciative Inquiry-explore the theories of organization change and large-group process on which the AI Summit is based; walk the reader step-by-step through the process of planning, conducting, and following up on an AI Summit; provide a series of case studies of the AI Summit in action; and share essential success factors-what they have learned in their work with AI and large-group processes that contributes to success in large-scale efforts. This book is an essential resource for anyone who works with Appreciative Inquiry, large group interventions, or whole-system change processes.
