Final answer:
Refreezing in Lewin's model is the stage where new changes are solidified into an organization's culture, ensuring stability and permanence.
Step-by-step explanation:
In Lewin's model of change, refreezing refers to the final stage where the changes that have been made are solidified into the organization's culture and practices, ensuring that the change is stable and lasting. In this stage, employees and management alike adapt to the new norms and the changes become the standard operating procedure. It is at this point where the organization's daily activities reflect the changes that have been implemented without the need for continual enforcement.
