This document provides an introduction to Appreciative Inquiry (AI), an approach to organizational change that focuses on strengths and successes rather than problems. It describes AI's key principles of focusing on what works well and envisioning a positive future. The document then outlines the 4D model of AI, which involves defining a topic, discovering strengths, dreaming of possibilities, and designing organizational change. Learners are prompted to reflect on examples of personal change and complete AI exercises to help understand and apply the approach.
