Decision Briefs

Use these templates to turn analysis into action instead of dumping findings.

Standard Decision Brief

1. Decision question.
2. Short answer.
3. Evidence: key numbers and comparison baseline.
4. Confidence: high, medium, or low, with one sentence why.
5. Caveats and what could still change the conclusion.
6. Recommended next action, owner, and due date.
