Review dimensions and scoring for root cause analysis quality assessment.
Expert approach to root-cause-analysis-qa in quality measurement. Use when working with .
Enhanced root cause analysis with explicit bias guards and stopping criteria. Use for incident post-mortems, bug investigations, and process failures where standard 5 Whys might mislead.
Conducts root cause analysis using enhanced 5 Whys methodology: multi-causal branching, evidence per level, backwards validation, and complete solutions for complex problems.

Review dimensions and scoring for root cause analysis quality assessment.
Check each WHY-to-WHY link.
Pass: logical mechanism (not just correlation) | no skipped steps | alternatives considered/eliminated | chain reads coherently both directions
Failures: correlation assumed as causation | causal chain gaps | single-path tunnel vision (first plausible cause accepted)
Severity: Critical -- wrong root cause = ineffective fixes.
Verify findings grounded in observable data.
Pass: each WHY cites specific evidence (logs, metrics, config, repro steps) | evidence verifiable by third party | timeline supports causality | hypotheses marked unverified
Failures: "Probably because..." without data | vague references ("logs show issues") | mixing facts with speculation unlabeled
Severity: High -- unreliable analysis undermines trust.
Verify competing explanations explored.
Pass: 2+ alternatives at WHY 1-3 | each pursued or eliminated with evidence | "why not" reasoning documented
Failures: stops at first plausible cause | alternatives mentioned but unevaluated | confirmation bias
Severity: High -- may miss actual root cause.
Verify analysis reaches fundamental causes.
Pass: each branch reaches WHY 5 (or justifies stopping with evidence) | final causes are actionable | causes explain symptoms when traced forward
Failures: stopping at WHY 2-3 | WHY 5 vague/philosophical not actionable | branches abandoned
Severity: High -- shallow analysis = band-aid fixes that recur.
Verify all symptoms accounted for.
Pass: all symptoms have causal branch | root causes collectively explain all | no orphan symptoms | cross-cause validation (no contradictions)
Failures: symptoms ignored | root causes explain primary but not secondary | contradictory causes without reconciliation
Severity: Medium -- incomplete analysis leaves unaddressed failures.
Verify solutions map to root causes.
Pass: every root cause has solution | immediate mitigations vs permanent fixes distinguished | no orphan solutions | prevention addresses systemic factors
Failures: solutions address symptoms not causes | root cause without fix | generic recommendations untied to findings
Severity: Medium -- untraceable solutions are guesses.
