Put the claim on the canvas. Then test it.

A repeatable path from what the team believes to what the evidence can support.

A concluded investigation read left to right: the hypothesis, four evidence cards, and the insights and verdict they led to.
Step one
A near-empty canvas holding a single hypothesis card, with the add-item menu open showing what else can go on it: evidence, insight, conclusion.

Write the hypothesis

State what the team thinks is true before anyone starts collecting proof. The claim stays visible as the investigation changes.

Step two
A close-up of the evidence behind one workstream: three cards naming their sources, linked to the insight they support.

Attach the evidence

Add interview notes, funnel numbers, support tickets, and links. Connect each observation to the claim it supports or contradicts. The evidence that disagrees stays visible.

Step three
A concluded investigation ending in a verdict card reading that the benefit-led headline lifted trial starts, with the insights it produced beside it.

Close the question. Keep the case.

Record the verdict with the evidence still attached. When the question comes back, reopen the project instead of rebuilding the reasoning from memory.

Close the question. Keep the case.

The claim is visible. The evidence is attached. The verdict has somewhere to live.
