Explanation:

Kurt Lewin’s Three Stages model or the Planned Approach to Organizational is one of the cornerstone models which is relevant in the present scenario even. Lewin, a social scientist and a physicist, during early 1950s propounded a simple framework for understanding the process of organizational change known as the Three-Stage Theory which he referred as Unfreeze, Change (Transition) and Freeze (Refreeze).

According to Lewin, Change for any individual or an organization is a complicated journey which may not be very simple and mostly involves several stages of transitions or misunderstandings before attaining the stage of equilibrium or stability.
