Final answer:
Kurt Lewin's theory of change consists of three phases: unfreezing, moving, and refreezing. This model helps in understanding and implementing change within organizations.
Step-by-step explanation:
Kurt Lewin's theory of change involves three phases: unfreezing, moving, and refreezing. This model is used to understand how to implement change within an organization or group. In the unfreezing phase, the existing state is prepared for change, which can be compared metaphorically to changing phase states in matter, like condensation where a gas turns to liquid, or freezing where liquid turns to solid. The moving phase is where the actual transition or change occurs. Finally, the refreezing phase solidifies the new state, ensuring that the change is sustained over time, much like how a liquid solidifies into a solid. Lewin's approach is still influential in the fields of organizational psychology and social psychology.
