A3 report on rising customer-onboarding drop-off

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