What is Behaviour Thinking?

A working discipline for seeing, testing and changing the behaviour that products, services, strategies and business models depend on.

Visible

What exactly must people do?

Testable

What proof do we have that they will?

Changeable

What must shift so action becomes more likely?

The short answer

Behaviour Thinking is a method for judging and improving work by the behaviour it depends on.

It works on anything with a person inside it. Products, services, strategies, policies, business models.

The ten-second question

What behaviour does this depend on?

Where good work fails

Walk across any park and you will find two paths. The paved one, laid by people who planned the park. And the worn line across the grass, made by thousands of feet that had somewhere to be. Planners call these desire paths. They are what happens when a design meets real behaviour, and real behaviour wins.

Every organisation has desire paths. The old spreadsheet doing the actual work. The redesigned service customers quietly avoid. The training everyone enjoyed and nobody applied.

Behaviour is the test

Desirable, feasible and viable are useful questions, and teams have become genuinely skilled at answering them. Behaviour Thinking adds one more: is it behaviourally fit? Can this work survive contact with what people actually do?

Desirable
Feasible
Viable
Behaviourally fit?

The plan may pass the visible tests and still fail at the behavioural one.

Where it came from

Behaviour Thinking was coined in 2014 and built the other way round from most methods: from live work, backwards into principles. It grew through practice rather than publication.

2014

The name

Coined in live project work, where good plans kept failing at the point where someone had to act.

2018

The equipment

Became tools through BehaviourKit: canvases, prompts and methods for working teams.

2022

The classroom

Entered education through courses and university teaching.

2026

The instrument

Now anchored by the Invisible Business Model Canvas for people make decisions early and BehaviourKit for people working on projects to influence behaviour.

Behaviour Thinking and Design Thinking

Design Thinking asks what people need. Behaviour Thinking asks what people must do. They work best side by side. Needs are states. Behaviours are events. The seam is the moment an idea becomes dependent on real action.

Starts with needs Starts with behavioural dependencies
Explores what is worth making Tests what the work relies on
Prototypes ideas Pressure-tests behavioural bets
Helps teams create Helps teams decide and adjust

Behaviour Thinking and behavioural science

Behavioural science is the evidence base. Behaviour Thinking is the working method built on it. Kept apart, the science fails in two ways: as a library of tricks bolted onto finished work, or as theory with no place to land inside a working week.
