Assumption Testing Matrix
Assumption Testing Matrix · Experiment tool
A product idea contains many assumptions, but the team does not know which one should be tested first.
Why use it
Rank assumptions by importance and uncertainty to focus experiments on the riskiest beliefs.
How to apply
- Define the specific management situation and desired outcome.
- Gather the minimum facts, constraints, and perspectives needed to use the tool.
- Apply Assumption Testing Matrix, make key assumptions explicit, and compare the result with realistic alternatives.
- Record the decision, next owner or action, and a testable criterion for the next step.
Output
A prioritized assumption map and experiment sequence.
