One-page A3
- Background — drop-off rose from 22% to 41% over Q2
- Current condition — 5 steps; users drop most at "connect data source"
- Goal — return drop-off to ≤ 25% by end of Q3
- Root cause analysis — OAuth scopes too broad, scares users
- Countermeasures — narrow scopes, add "why we need this" inline
- Plan — ship in 2 weeks; monitor weekly; review in 6
- Follow-up — re-run analysis at week 6 and report results
