Kurt Lewin developed a change model involving three steps: unfreezing, changing and refreezing. For Lewin, the process of change entails creating the perception that a change is needed, then moving toward the new, desired level of behavior and, finally, solidifying that new behavior as the norm.

1. Unfreeze: The first step of accepting that change is necessary. Therefore, breakdown the current organization structure and start from core to build a new structure. This enables organizations to reassess the processes.
2. Change: The phase of resolving the issue identify by unfreeze stage. This involves the transition from previous systems to new environment.
3. Refreeze: This is the part where organization ensures the successful implementation of change.
