Step 1 / 5 · 10 min

Name the decision

Prevent a dashboard from becoming the deliverable.
  1. Write the choice and decision date.
  2. Name who has authority to act.

Field tools

Use the instrument, not a blank page.

Copy these into your interview, agent, review, or working document. They are specific to this repetition.

Event contract

Give each event one behavioural meaning.

EVENT: [actor]_[past-tense action]_[object]
FIRES WHEN: exact observable condition
REQUIRED PROPERTIES: identity, object, source, timestamp
MUST NOT FIRE WHEN: test/retry/preview conditions
QUALITY CHECK: raw records or session replay used to verify it
DECISION SUPPORTED: continue / change / stop

Metric review agenda

Run this ritual before proposing features.

1. Is the data trustworthy enough to decide?
2. Which segment moved, and what mechanism could explain it?
3. Where did users fail or need rescue?
4. What do five raw examples show?
5. Which pre-committed rule applies?
6. What will we change, by whom, by when?

Calibrate judgment

Compare the evidence, not the polish.

Useful

Metric with a consequence

A team is testing guided setup for collaborative workspaces.

Continue only if 35% of new workspace owners invite a teammate and both complete one shared task within 24 hours, while fewer than 10% need support rescue. Review by team vs solo intent and replay five failures before changing UI.

Why it works: The event proves collaborative value, includes a quality guardrail, and dictates the next decision.

Looks finished. Is not.

Dashboard theatre

Track signups, DAU, button clicks, time on page, and NPS. Review monthly and improve onboarding if engagement is low.

Why it fails: The metrics do not define value, cannot diagnose failure, and have no pre-committed action.

Review → revise → repeat

The artifact is the beginning of the rep.

Check only standards your current artifact actually meets. Then record one consequential revision before exporting it.
