COM-B Model

TTool · COM-B Model

By , Editor · · What’s Next

People know what they should do. They've had the training. They're still not doing it. You're about to schedule more training.

COM-B is Susan Michie's behaviour change framework. You diagnose which of three conditions is missing — Capability (physical and psychological), Opportunity (physical and social), or Motivation (reflective and automatic) — because all three must be present for behaviour to change.

Three stacked component blocks - CAPABILITY ("Can they do this?"), OPPORTUNITY ("Is the environment letting them?"), and MOTIVATION ("Do they want to?") - converging on a single BEHAVIOUR outcome, captioned "All three must hold. Training only fixes capability."
