Estimate time and effort with an outside view instead of relying only on the current plan.
Open →Decision technique
Decision journal
Preserve what was known, expected and uncertain before the outcome changes memory.
When to use
A specific reasoning move for a specific problem.
For important forecasts, project decisions, incident reviews and repeated professional judgments.
Procedure
Run the technique.
- Record the decision and date.
- Record evidence, assumptions and uncertainty.
- Write what would change the decision.
- Review the original record after the outcome before drawing lessons.
Limit
What this technique cannot guarantee.
A journal improves learning only if it is written before the result and revisited later.
Situations
Where this may be useful.
Separate what was knowable during an incident from what became obvious only after the outcome.
Open →Judge performance without letting one recent result or known outcome rewrite the quality of the underlying work.
Open →Check whether a score is still a useful proxy for the real goal and whether the comparison is being interpreted consistently.
Open →Evidence-linked concepts
Why this check may matter.
Practice this technique

After an outage, the failed component is easy to identify. Reviewers say the on-call engineer should have known immediately, although several alerts looked equally plausible during the incident.
Skill: MetacognitionOpen scenario →A manager skipped required checks but the project succeeded. The review treats the success as proof that the manager’s approach was excellent.
