systematic-debugging

Systematic debugging is a structured four-phase investigative process that traces bugs, test failures, and unexpected behavior to root causes. Use it for production incidents, flaky tests, and multi-component scenarios before proposing any fixes.

Debug flaky failures and incidents through a four-phase workflow: start with initial investigation, perform pattern analysis, conduct hypothesis testing, then implement fixes with defense-in-depth validation across multiple layers to ensure root-cause diagnosis.

Yes, hypothesis-driven debugging works for multi-component systems by enforcing pattern analysis and hypothesis testing before fixes. It applies defense-in-depth validation across multiple layers to ensure accurate root-cause diagnosis even under time pressure.

Stop random fixes from creating new bugs by enforcing a four-phase investigation with explicit stop rules and anti-patterns. This mandates root-cause diagnosis and defense-in-depth validation across layers before any implementation begins.

The main limitation of defense-in-depth debugging during production incidents is the time required to validate data across multiple layers and test hypotheses. Strict adherence to explicit stop rules and anti-patterns may conflict with extreme time pressure.
