failure-diagnosis

Root cause analysis for software failures requires separating symptoms and triggers from the actual cause through evidence-first reasoning. This discipline validates falsifiable hypotheses with confirming and refuting evidence to prevent trigger-only conclusions.

Structuring a postmortem requires separating root cause and contributing factors, then enforcing explicit incident roles and severity handling. This yields verifiable CAPA-style action items for measurable prevention and documented reproduction infeasibility.

Yes, you can debug data anomalies and concurrency issues using hypothesis validation. This requires formulating falsifiable predictions and gathering both confirming and refuting evidence to rigorously validate or eliminate each diagnostic hypothesis.

You need change-failure correlation when diagnosing software failures to link observable evidence with recent system modifications. This separates triggers from root causes when diagnosing production incidents, performance regressions, or third-party integration problems.

When reproduction is not possible, incident diagnosis completion criteria require an evidence chain proving infeasibility. The diagnosis must conclude with specific, verifiable postmortem and prevention action items to ensure measurable corrective outcomes.
