This chapter discusses change management and organizational change. It defines organizational change as the movement of an organization away from its present state toward a desired future state. There are three main forces that drive organizational change: internal forces, external forces, and the domino effect. The chapter outlines various models for managing organizational change, including Lewin's three-step model of unfreezing, changing, and refreezing. It also discusses sources of resistance to change and strategies for managing resistance, such as communication and involvement.
