systematic-debugging

Systematic debugging is a structured workflow that identifies root causes before proposing fixes. You should use it for any technical issue, including test failures, production bugs, and unexpected behavior, to avoid guessing and patching without understanding.

To debug a CI pipeline failure, start by reproducing the bug, collecting errors and logs, and beginning Root Cause Investigation. This structured approach guides you to reproduce, measure, and confirm the root cause before applying any fixes.

A structured debugging workflow implements four phases: Root Cause Investigation, Pattern Analysis, Hypothesis and Testing, and Implementation. These phases enforce methodical debugging through error review, reproducibility, data gathering, and validated fixes.

To test a hypothesis when debugging unexpected software behavior, follow the Hypothesis and Testing phase, which requires thorough analysis and evidence gathering to validate the root cause before you proceed to the Implementation phase with confirmed fixes.

Yes, systematic debugging applies to any technical issue, including production bugs and test failures. It enforces an evidence-driven process requiring reproduction, data gathering, and traceability across components to ensure root causes are confirmed.

You should gather evidence before fixing a software bug because systematic debugging solves the problem of guessing and patching without understanding root causes. Evidence-driven reproduction and data gathering ensure traceability and validated fixes.
