This document discusses organizational change and models for managing change. It presents two models of the change process: the Growth Curve Model and Lewin's unfreezing-changing-refreezing model. Reasons for resistance to change are described as well as methods for dealing with resistance like education, participation, and negotiation. Organizational development is presented as a change strategy using interventions at the individual, small group, and organizational levels. Large-scale change and total quality management are also summarized.
