Change management models compared: ADKAR, Kotter and Lewin
What each model is good at, where it falls short and how to choose one for your program.
A change management model gives a program a shared language and a sequence of things to get right. The three most widely used models answer different questions.
Lewin: the simple three-stage view
Lewin describes change as three stages: unfreeze current habits, change to the new way of working and refreeze so it becomes normal.
- Strength: easy to explain to any audience.
- Limit: gives little detail on what to do inside each stage.
- Use it for: framing smaller changes and giving leaders a quick mental picture.
Kotter: eight steps for leading organization-wide change
Kotter’s model walks leaders through creating urgency, building a guiding coalition, forming a vision, communicating it, removing obstacles, creating short-term wins, building on them and anchoring the change in culture.
- Strength: focuses on leadership, momentum and visible early results.
- Limit: it describes what leaders do, not how each individual experiences change.
- Use it for: large programs that need sponsorship across many teams.
ADKAR: guiding each person through change
ADKAR follows the individual through five outcomes: awareness of the need, desire to take part, knowledge of how to change, ability to do it and reinforcement to keep it.
- Strength: pinpoints why adoption is stuck for a given group, for example people know what to do but lack the ability.
- Limit: concentrates on individuals, so it needs to be paired with program-level leadership.
- Use it for: planning training, communication and support for the people affected.

Frequently asked questions
Which change management model is best?
No single model is best. Choose by what you need: ADKAR works well for guiding individuals, Kotter for leading large organizational programs, and Lewin for a simple view of the overall stages.
Can we combine change management models?
Yes. Many programs use one model to set the program-level approach and another to plan support for individuals, as long as the team shares a single plan.
