What does refreezing mean in organisational development?

Refreezing in a business and management context is in reference to the psychologist, Kurt Lewin and his theory of planned change.
The theory has three steps; unfreezing, changing and refreezing.
Refreezing is the final process after change has been initiated in an organisation. The change leaders job is to stabilise the change to ensure long-term effectiveness. The change leader can provide any support, guidence or resources to ensure the change remains, they can also provide rewardsand positive reinforcement.
If the refreeze stage is done well, the intended change will last and become the normal for an organisation, but if it is done poorly, the organisation can revert back to the original very easily.
