Which concept is not part of Lewin's change theory?

Lewin's change theory consists of three main stages: unfreezing, changing (or transition), and refreezing. In the unfreezing stage, existing behaviors and practices are recognized as being outdated or ineffective, and there is a need to prepare for change. The second stage, often referred to as the "changing" or transitional phase, involves implementing the new behaviors or processes. Finally, in the refreezing stage, the changes are solidified into a new status quo to ensure their sustainability.

The concept of “transitional freezes” is not recognized in Lewin's framework. Instead, the theory focuses on the importance of moving through identified stages without suggesting a separate stage called "transitional freezes." Understanding Lewin's model revolves around the idea that effective change requires preparing individuals to let go of old habits, transitioning to new ones, and then solidifying these changes into everyday practice, which makes the other three concepts integral to the theory.
