Phase 0: Problem Intake
💾 Investigation:
F

Root Cause Analyzer

Structured problem-solving powered by 8D/A3 methodology. Describe a quality issue, defect, or operational problem — I'll walk you through a rigorous investigation.

Conversational

Not a form. A structured discussion that draws out what you know.

Methodology-Enforced

8D/A3 phases in the right order. No skipping steps.

Knowledge Graph

See connections between entities grow in real-time.

Try it on a real problem. The full investigation is free on-screen.

What do you need? Pick the deliverable — not everything is an 8D.
Root-Cause Summary

Quick Root-Cause Fast

Get to a defensible root cause + escape point fast. A one-page summary, not a formal record.

NCMR-lite Record

NCMR-lite

Disposition + root cause for an internal nonconformance. Lighter than a full 8D.

A3 Report

A3

One-page Lean / Kata problem-solving story: condition, analysis, countermeasures, plan.

CAPA Record

CAPA Coach

Full investigation as a CAPA record — corrective + preventive action, effectiveness check.

8D Report

Full 8D

Customer / auditor-facing formal 8D (D1–D8) — the complete deliverable in the structure auditors expect.

Every mode runs the same guarded analysis. Your progress is saved automatically — use your resume URL to return anytime. Not sure what you'll get? See real sample reports — the same case in all five tiers — or read who built this.

Before you begin: the quality of the analysis depends entirely on the accuracy and completeness of the information you enter — the tool does not verify your inputs, and a qualified person in your organization must review and approve any output before it is used. Only upload data you're authorized to share; avoid personal data (PII/PHI) where possible.
