Final answer:
Unfreezing in Lewin's model is the first stage of organizational change, involving the disruption of the status quo and preparation for new methods.
Step-by-step explanation:
Unfreezing in Lewin's model refers to the first stage in the three-step process of organizational change that social psychologist Kurt Lewin developed. This stage involves preparing an organization to accept that change is necessary, which entails breaking down the existing status quo before new ways of operating can be introduced. The unfreezing phase aims to overcome inertia and dismantle existing mindsets. It can involve challenging current beliefs and values and confronting employees with new perspectives or the need for change. This often requires participation and support from leadership and management to communicate the need for change and create the motivation necessary to implement it.
