Create a reusable template for an experiment brief

An experiment brief should make the planned decision, comparison and interpretation rules clear enough for another operator to run the trial.

A practical procedure

1. Create fields for the problem, hypothesis, changed variable and fixed conditions.

2. Add the outcome definition, sample scenario, observation period and failure rules.

3. Include a result section for evidence, limitations and the keep-or-revise decision.

Worked example: a fictional session

A fictional caption brief specifies the exact clip and phone view, preventing the second operator from testing a different demonstration.

Check the limits

A completed template is not evidence that the experiment was actually executed.
