Lewin’s three-stage change model
Lewin’s three-stage model describes unfreezing established patterns, moving or changing, and refreezing or stabilising the new pattern. Unfreezing builds understanding and readiness; changing develops and applies the new arrangements; stabilising supports their continuing use through systems, habits and reinforcement. The framework does not require permanent rigidity after a change or imply that people simply follow three instructions.
Worked example
A team understands why a failing process must change, learns and tests the replacement, then embeds it through clear responsibilities, feedback and revised measures. Managers continue to review whether it remains suitable.
Common mistake
Do not interpret refreezing as prohibiting future adaptation or assume communicating a change is the same as enabling and sustaining it.
