Final answer:
The three levels of achieving change are Unfreezing, Changing, and Refreezing.
Step-by-step explanation:
The three levels of achieving change are Unfreezing, Changing, and Refreezing.
This model was developed by Kurt Lewin, a social psychologist who proposed that in order to successfully implement change, individuals must go through a process of unfreezing their current behavior, making the necessary changes, and then refreezing the new behavior as the new norm.
During the unfreezing phase, individuals become aware of the need for change and start to question their current practices. In the changing phase, new behaviors and practices are implemented. Finally, in the refreezing phase, the new behaviors and practices are solidified and become the new norm.
