What main concept does Lewin's change model utilize?

Lewin's change model primarily utilizes the concept of Force Field Analysis. This model emphasizes the idea that in any situation, there are forces that support change and forces that oppose it. In order to successfully implement change within an organization, these forces must be understood and managed.

Force Field Analysis involves identifying and evaluating the driving forces (those that facilitate change) and restraining forces (those that hinder change). By visualizing these forces, leaders can create strategies to strengthen the driving forces and weaken the restraining ones, thus facilitating a smoother transition during the change process. This approach is foundational in understanding how to navigate and guide organizational change, making it integral to Lewin's model.

In contrast, the other options touch upon different concepts. Incremental Learning relates to gradual knowledge acquisition, Culture Shock pertains to the psychological effects of transition between cultures, and Situational Leadership is a management style focused on adapting leadership behaviors based on team needs. While these topics are important in their own right, they do not align with the core principles of Lewin's change model like Force Field Analysis does.
