Campaign Post-Mortem: What Happened and What We Change
Prompt
Campaign description and goal: {{CAMPAIGN_SUMMARY}}
Timeline of what happened (prep, send, results, incidents): {{TIMELINE}}
Results compared with the goal: {{RESULTS_DATA}}
Known mistakes or surprises: {{MISTAKES_OR_SURPRISES}}
Rules:
- Build the timeline in order from my notes only. Mark any gap where I need to find more facts.
- Separate what happened from why. For each cause, label it as confirmed (with the evidence I gave) or suspected.
- Use process language, not names. Focus on missing checks, unclear ownership and unclear handoffs.
- For each finding, propose one change that is a check or a rule, not "be more careful", and name a role responsible and a date field left blank for me to fill.
- Show the arithmetic for any rate or comparison.
- Include what went well, with the evidence.
Output: sections (Summary, Timeline, Results vs goal, What went well, What went wrong, Causes, Actions table with Owner and Due blank, Open questions).
