This document outlines the key aspects of managing change processes. It begins by defining change and discussing how people typically react to change. It then explores factors that drive change both externally from the environment and internally within organizations. Three main strategies for implementing change are described: power-coercive, rational-empirical, and normative-re-educative. Lewin's three stage model of change and a systems model of service change are also presented. The document provides guidance on developing a change plan, identifying support and resistance, and working with resistance to change. It concludes by emphasizing the importance of leadership styles in managing the change process.
