Get the key insights and tools to start using Behavioural Design

If you’re new to behavioural design, this page brings together everything you need to get started. With key insights, beginner tools, and step-by-step methods to help you design for real human behaviour.

Learn how to understand why people do what they do, how to map the systems around them, and how to design practical interventions that make positive behaviour easier.
Each tool and guide on this page is written in plain English, so you can learn by doing, not by decoding theory.

You’ll explore:

• Behavioural Design principles : how design shapes what people actually do

• Step-by-step process : from defining the behaviour to testing your intervention

• Free tools and templates : including the Action Sorter, COM-B Canvas, Drive Grid, Outcome Mapping, and more

• Practical insights : how to find the root causes of behaviour, build motivation, and measure what changes

Whether you’re a designer, policymaker, strategist, or someone curious about human behaviour, this is your starting point for applying behavioural science to real-world design challenges.

Created and written by Lauren Kelly, founder of BehaviourKit, this collection of methods helps you learn the foundations of behaviour change in a clear, ethical, and hands-on way.
