This document compares five popular change management models:
1. Kotter's 8-step model focuses on buy-in and provides clear steps but is top-down with no room for participation.
2. Bridge's transition model helps understand how people feel during change but is not a full change management model.
3. Rogers' technology adoption curve helps identify audience and influencers but people's adoption varies over time.
4. Kubler-Ross' change curve captures individual reactions to change but assumes all change is bad and stages are difficult to identify.
5. Prosci's ADKAR model encapsulates both business and individual dimensions of change and provides a clear management checklist.
