systematic-debugging

Systematic debugging is a disciplined, four-phase workflow enforcing root-cause investigation before any code changes. You need it for production incidents, test failures, and performance issues to prevent symptom-level fixes and ensure auditable traces.

To find the root cause of a bug, begin with Phase 1: Root Cause Investigation, then proceed through Pattern Analysis, Hypothesis Testing, and Implementation. You must complete all four phases in order before proposing fixes to ensure true root-cause resolution.

Yes, systematic debugging works for software bugs, test failures, production incidents, and performance issues. It applies a defense-in-depth mindset to validate data across entry, business, environment, and debugging contexts for comprehensive issue resolution.

The best way to stop symptom-level fixes is to enforce a root-cause investigation workflow with explicit stop rules. Systematic debugging mandates completing Phase 1 before any fixes, ensuring you trace the actual problem origin before modifying code.

No, you cannot skip the root cause investigation phase. The systematic debugging workflow requires completing all four phases in order, with Phase 1 mandatory before fixes, to maintain a defense-in-depth validation approach and prevent incomplete resolutions.
