Definitions:

Freezing

A physical process where a liquid turns into a solid when its temperature is lowered below its freezing point.

Refreezing

The final stage in the change process where new behavior becomes integrated into the norm, ensuring stability.

Moving

The act or process of changing physical location or position, often implying a transition or passage from one place to another.

Lippitt's Theory of Change

A model that outlines the steps necessary to implement change successfully, focusing on the roles of the change agent and the change process.
