Goal: identify need, scope and a testable criterion in Card E, then independently apply the same analysis to Check A. Say: “Name what we can observe, not just what we hope.”
- 0–2: Model “find an item code before rehearsal” as the prop-shelf need.
- 2–5: Contrast “easy to use” with a trial in which a crew member finds a code in a set time; do not preview Check A.
- 5–17: Give the fresh check, collect a first response in any route.
- 17–22: Use public key for feedback; invite a revised criterion with condition and measure.
- 22–25: Record a next move: need/evidence, scope, missing fact or criterion.
Routes: written four-part analysis; spoken analysis with a captured trial condition; labelled scope/criterion strips with dictated evidence. Other domains: Day 5 swaps after the check. Optional/home: invent a criterion a person could actually test in a paper trial. Move: if a learner claims “everyone finds it easily”, ask for the stated group, task and threshold. This public check is not secure or formal assessment.
