Tool: Intervention Design

FREE BEHAVIOURAL DESIGN TOOLS

Design interventions that create real behaviour change.

The Intervention Design method helps you move from insight to action. It combines the COM-B model, intervention functions, and Behaviour Change Techniques (BCTs) to structure ideas that actually shift behaviour.

Use it to:

  • Turn behavioural insights into targeted interventions

  • Choose the right intervention functions for your goal

  • Match BCTs to your chosen function and touchpoint

  • Build “How might we…” statements that link cause to outcome

A practical framework for turning theory into tested, design-led interventions.
