systematic-debugging

Systematic debugging is a disciplined four-phase framework to uncover root causes before applying fixes. You need it for any bug, test failure, or unexpected behavior in development, testing, or production to reduce rushed decisions and rework.

To find the root cause of a bug, follow a structured process: investigate root causes in Phase 1, analyze patterns in Phase 2, test hypotheses in Phase 3, and implement fixes in Phase 4. This prevents shortcut fixes under pressure.

The best way to stop applying shortcut fixes is to enforce a four-phase debugging framework that requires explicit root-cause investigation, pattern analysis, and hypothesis testing before implementation, ensuring disciplined experimentation before changes.

Yes, you can integrate systematic debugging with test-driven development. The four-phase framework requires explicit hypothesis testing and pattern analysis, naturally aligning with test-driven development practices to confirm root causes before implementing fixes.

During root cause investigation, the main anti-patterns to avoid are skipping phases and applying shortcut fixes under pressure. If tempted to skip steps, review the Phase 4 anti-pattern guidance to maintain disciplined experimentation before changes.
