Draft outline details
Step by step
- Present the initial choice and its scenarios.
- A reviewer from operations asks for the recovery procedure; walk it step by step.
- Planned mistake: defend the choice instead of testing the claim. Fix: time the recovery in a rehearsal; it takes 50 minutes against a 15-minute target.
- Revisit the options with this evidence; a simpler option now meets the target.
- Update the ADR: status, new decision, the evidence, what was learned.
- Discuss how to make changing a decision socially safe.
