How to structure your root-cause analysis

Verify the signal before proposing fixes. Narrow the blast radius, compare hypotheses, and ask for evidence that separates them.

  1. Define the metric precisely and confirm the drop is real rather than an instrumentation change.
  2. Segment by time, platform, geography, cohort, funnel step, and release exposure to localize the issue.
  3. Build internal and external hypotheses, then rank them by likelihood, impact, and speed to test.
  4. Request discriminating evidence, identify the root cause, and only then discuss mitigation and prevention.
