systematic-debugging

Root cause debugging is a four-phase workflow that forces you to reproduce the issue, collect evidence, and map data flow before proposing any fixes, reducing time wasted on symptomatic patches.

Debug a production incident by following a disciplined investigation workflow: reproduce the issue, analyze patterns against working references, formulate a single hypothesis, and implement the fix with defense-in-depth checks.

Your debugging process likely shortcuts because it lacks explicit stop rules; a systematic approach enforces complete evidence gathering in Phase 1 and pattern analysis before allowing any hypothesis testing or fixes.

The best way to debug flaky tests is using a hypothesis-driven workflow: compare the failing test with working references to identify differences, then test a single hypothesis minimally before applying a fix.

Yes, hypothesis testing is ideal for complex bug hunts; it requires formulating a single hypothesis, testing it minimally, creating a failing test, and applying a single fix to verify the outcome.

The limitation of this phase-based debugging approach is its strict enforcement; it requires completing the full root cause investigation and pattern analysis phases before proceeding to hypothesis testing, which may slow down simple fixes.
