Step-by-step explanation:
In the context of Kurt Lewin's three-stage model of change management, the unfreezing stage involves preparing an organization to accept that change is necessary. This is achieved by breaking down the existing status quo before you can build up a new way of operating. Key activities during this stage might include identifying issues, challenging current beliefs, norms, values, and behaviors, and recognizing the need for change within the organization. In this stage, effective communication and the involvement of all members of the organization in the process are crucial for acknowledging the need for change and establishing a receptive mindset.
