This document provides an overview of Appreciative Inquiry (AI), an approach to organizational and social change. It defines key AI concepts, outlines the 5 core principles and 5 basic steps, and discusses how AI differs from traditional deficit-based change models by focusing on an organization's strengths rather than weaknesses. The document also reviews how and when AI was developed, common applications in schools, communities and organizations, and concludes with an activity to demonstrate paired affirmative interviews, a tool used in AI.
