Build an Experiment Design Canvas in Miro
Use the canvas to make an experiment plan reviewable before execution. It is a manual planning artifact: the appropriate research or analytics system performs the test and analysis, not the board itself.
Before you start: Have a product decision, testable hypothesis and owner. Involve someone who understands the measurement and implementation constraints.
Worked example: A revised invite message should increase successful acceptance among eligible new owners without increasing accidental invitations. Capture both the primary outcome and the plausible harm.
Step-by-step guide
State the hypothesis
Describe the change, audience and expected behavior. Explain the mechanism rather than writing only an optimistic target.
Define the comparison
Choose what the treatment is compared with and how eligibility or assignment works. Label a non-random comparison honestly.
Specify measurement
Name the success outcome, counting unit and observation window. Link the event or research definition used to assess it.
Add guardrails
List plausible harms and operational failure signals. Keep them related to the intervention instead of adding unrelated metrics.
Agree the decision rule
Write proceed, stop and inconclusive conditions before results arrive. Include ownership for monitoring and analysis.
Review readiness
Check implementation, exposure and data quality with a small controlled test. Preserve the approved plan and record deviations during execution.
Common mistakes
Canvas substitutes for design
The board cannot fix weak assignment or measurement.
Many unrelated metrics
That makes convenient success stories easier.
No inconclusive outcome
Uncertainty is a legitimate result.
Tips
Keep the original hypothesis immutable in the record.
Link measurement definitions.
Name who can stop the test.
