Feature: [NAME]
Expected outcome: [WHAT YOU PREDICTED]
Actual outcome: [WHAT HAPPENED]
Analyze this failure in 4 parts:
1. Prediction errors: What did I misunderstand about users/market/tech?
2. Execution gaps: Where did we cut corners that mattered?
3. Unavoidable factors: What was genuinely outside our control?
4. Hidden wins: What did we learn that makes the next feature better?
Be specific. No "we should've done more research" platitudes. Tell me the exact wrong assumption I made.
