systematic-debugging

Systematic debugging is a structured investigation process to identify the root cause of technical issues before applying fixes. You need it for production incidents, test failures, build errors, and performance regressions to prevent new bugs from fixing symptoms.

To find the root cause of test failures, follow a four-phase workflow: Root Cause Investigation, Pattern Analysis, Hypothesis Testing, and Implementation. Mandatory checks enforce investigation before any code changes, preventing shortcuts under time pressure.

The best way to debug build errors without creating new bugs is to enforce systematic investigation through pattern analysis and hypothesis testing before implementation. This prevents wasted time and avoids introducing regressions from symptom patching.

Yes, systematic debugging integrates with test-driven development through built-in hooks. The workflow complements TDD by ensuring root cause analysis and hypothesis testing precede implementation, working alongside verification practices for reliable fixes.

Systematic debugging prevents shortcuts during production incidents through pressure-resistant rules and mandatory checks. The workflow enforces a four-phase process—investigation, pattern analysis, hypothesis testing, and implementation—with anti-pattern warnings that stop symptom-only fixes.

Fixing symptoms without root cause analysis creates more bugs because underlying issues remain unresolved, leading to regressions and wasted time. Systematic debugging enforces hypothesis testing and pattern analysis before implementation to ensure fixes address actual causes.
