systematic-debugging

Systematic debugging uses a 4-phase workflow—Reproduce, Isolate, Understand, and Fix & Verify—to diagnose issues methodically. This evidence-based process reduces guesswork by enforcing reproducible steps, root-cause analysis with the 5 Whys, and verification checks to prevent regressions.

Apply the 5 Whys technique alongside structured isolation questions to trace misleading symptoms to their source. This prevents quick fixes that mask underlying problems and ensures you address the actual cause, not surface symptoms.

The isolation phase uses targeted questioning and evidence gathering to narrow the problem's scope—whether it's in your code, a dependency, or system configuration. This prevents debugging entire systems when the issue is localized.

Quick fixes skip root-cause analysis, leaving the underlying problem to resurface elsewhere. This workflow enforces verification and regression checks after fixes, catching side effects before they reach production.

Yes. The systematic approach works across codebases managed with git and other version control tools. Reproducible steps and verification create an audit trail that integrates with your development workflow and version history.
