Lean experiment canvas
A lean experiment canvas turns a promising idea into a test that a team can evaluate. In this example, the team believes that giving patients a direct reschedule link will reduce missed visits and last-minute calls. It names the people who should receive the message, the current experience used for comparison and the timing of the new reminder. The measurement section includes both the intended result and a guardrail: a lower missed-visit rate should not come at the cost of more cancellations. This structure helps a team avoid vague experiments. After the test, the group can keep, revise or stop the intervention based on the agreed decision rule.
Open it in the AI editor with a prompt pre-filled — keep what works, change what doesn't.
Scenario
A service team is testing whether a reminder change improves appointment attendance.
Key decisions
- Write a prediction: Name the expected behavior change before launching.
- Define the audience: Exclude people who cannot receive the intervention.
- Set a guardrail: Check cancellations as well as missed visits.
When to reuse this
Use when a team needs to turn an idea into a bounded test with a clear decision rule.
