The refreezing step of Kurt Lewin's change model is unrealistic when environmental and technological changes are everyday realities.

The refreezing step is based on the assumption that once a change has been made and implemented, the organization should stabilize and maintain the new state by reinforcing the new behaviors and attitudes. However, in today's rapidly changing environment, it is not always realistic to maintain the same state as new technologies, and environmental changes require constant adaptation and adjustment. Therefore, the refreezing step can be challenging, and organizations need to be flexible and adaptable to stay competitive.
