Platform Strategy That Ships: The 90-Day System I Trust More Than AI Roadmaps

Platform Strategy That Ships: The 90-Day System I Trust More Than AI Roadmaps

Short summary

A platform leader shares a detailed postmortem of an AI code review bot that added half a day to PR cycle time and saw engagement collapse by day 60, despite a $144K/month savings model. The bot performed well in Java and Python but poorly in Swift and BrightScript, and noisy suggestions eroded developer trust faster than tuning could recover it. The author advocates for 90-day strategy cycles with pre-defined ship and kill criteria, named owners, and decision logs over slide-deck roadmaps.

  • AI code review bot added 0.5 days to PR cycle time and engagement collapsed by day 60 despite a $144K/month savings model
  • Cross-language quality gap (good in Java/Python, bad in Swift/BrightScript) broke developer trust
  • Author now uses 90-day cycles with pre-defined kill criteria, named owners, and decision logs

Generated with AI, which can make mistakes.
