Lewin's Change Management Model is a framework that helps organizations implement change effectively. It consists of three main stages: Unfreeze, Change, and Refreeze. In the Unfreeze stage, the organization prepares for change by recognizing the need for it and breaking down existing habits. During the Change stage, new processes or behaviors are introduced, and employees are supported through the transition. Finally, in the Refreeze stage, the organization solidifies the new changes, ensuring they become part of the culture and preventing a return to old ways. This model emphasizes the importance of preparing, implementing, and stabilizing change.
