Why

A structured approach to root cause analysis that keeps you from shipping band-aids instead of fixes. It walks you through the classic Five Whys technique, pushing past surface symptoms like "payment service threw an exception" down to systemic issues like "our migration review process doesn't check query performance." The examples are solid and realistic, covering production bugs, CI/CD failures, and multi-branch scenarios where one problem has multiple root causes. The real value is in the discipline it enforces. Most debugging stops at the first plausible explanation, but this keeps asking why until you hit process gaps or missing automation, which is usually where the actual fix lives.
