Global 8D. Structured response. Audit-ready closure.
The 8-Discipline problem-solving framework — all nine disciplines, AI-assisted where it matters most, gated for rigour, and connected directly to your RCA investigation. From team formation to signed-off closure in a single auditable workflow.
BACKGROUND
The industry standard for structured problem response
Global 8D (G8D) is the structured, team-based problem-solving methodology developed by Ford and adopted across automotive, aerospace, and industrial manufacturing. It is the mandated response framework for customer-specific requirements under IATF 16949.
Where RCA answers “what caused the failure,” 8D answers “what do we do about it” — structuring the team response from emergency containment through permanent corrective action, systemic prevention, and formal sign-off.
Most teams document their 8D response in a Word table or Excel template — with inconsistent structure, no evidence traceability, and no connection to the underlying investigation. This platform changes that.

What makes this different from a template
- D2 problem description is AI-generated from your RCA findings — not typed from memory
- D4 root cause pulls directly from the linked RCA investigation — no re-entry
- D5 corrective actions are AI-proposed, based on the specific root cause — not generic boilerplate
- D7 lessons learned are AI-generated and injected into the platform knowledge base — so the next investigation knows about this failure
- D8 sign-off is a gated workflow step — the report cannot be closed without completing all disciplines
- Every discipline is persisted in Firestore — the record exists even if the browser closes
Where It Fits
Global 8D is the Deploy phase of the 5-D investigation workflow.
The RCA AI Engine takes you through Define, Diagnose, and Design — establishing root cause, surfacing contradictions, and refining the analysis. Global 8D is where investigation becomes action: the structured team response that deploys the corrective fix. CAPA closes the loop with effectiveness verification at Deliver.

The Framework
Nine disciplines. Every problem.
D0 through D8 — the complete 8D lifecycle, with AI assistance applied precisely where synthesis and generation add the most value..
D2 – AI ASSISTED
Problem Description
IS / IS-NOT structured problem statement generated from the linked RCA output. Quantified in terms of object, defect, location, timing, magnitude, and trend — directly from evidence, not from memory.
GENERATED FROM RCA FINDINGS
D4 – RCA LINKED
Root Cause Analysis
D4 links directly to an existing RCA investigation in the platform. The root cause narrative, probable causes, and evidence citation map are pulled through automatically — no re-entry, no paraphrasing.
EVIDENCE-GROUNDED, CITED
D5 – AI ASSISTED
Permanent Corrective Actions
AI proposes corrective actions directly targeted at the root cause — not generic actions from a library. Each proposed action is mapped to the specific failure mechanism identified in D4.
ROOT-CAUSE SPECIFIC
D7 – AI + KNOWLEDGE BASE
Systemic Prevention & KB Injection
AI generalises the corrective actions into systemic preventive measures across related assets, processes, and product lines. Lessons learned are injected into the platform knowledge base — so future RCA investigations on similar failures retrieve this case as prior context.
KB INJECTION LOOP
D8 – GATED SIGN-OFF
Team Acknowledgement & Closure
D8 is a workflow gate — closure requires all disciplines to be complete. The signed-off report is generated as a structured PDF covering all nine disciplines with full evidence traceability.

D0, D1, D3, D6 — Team Led
Emergency Response, Containment, Implementation
Structured input forms for the disciplines that require human judgment and team coordination — emergency actions, team roster, interim containment verification, and implementation record. Fully persisted and audit-ready.

How It Works
From incident to closed report
The G8D workflow follows the investigation — it does not run parallel to it. Every discipline builds on the evidence already established in the RCA.
One Workflow. No Re-entry
Traditional 8D reports are written after the investigation — from memory, in a template, by whoever has time. Evidence gets paraphrased. Root causes get simplified. The connection between what the data showed and what the report says degrades with every edit.
In this platform, the 8D report is generated from the same evidence base as the RCA. D4 does not ask you to summarize the root cause — it reads it from the investigation. D5 does not ask you to list corrective actions — it proposes them from the root cause. The report reflects what the evidence actually showed.
- Run RCA investigation — 20 evidence documents, 13 modules
- Create linked G8D job from the RCA Cockpit
- D1: Add team roster and champion
- D2: AI generates IS/IS-NOT from RCA findings — review and confirm
- D3: Record interim containment actions
- D4: Root cause pulled from linked RCA automatically
- D5: AI proposes corrective actions — review, edit, assign owners
- D6: Record implementation and verification evidence
- D7: AI generates systemic prevention — KB injection triggered
- D8: Gate check passes — sign off, export PDF
Platform Integration
RCA and G8D share one evidence base
Neither discipline works in isolation. Together they cover the full problem-solving lifecycle — from root cause identification to corrective action closure.
G8D D7 → Knowledge Base
D7 lessons learned are not just documented — they are injected back into the platform knowledge base. The next RCA investigation on a similar failure mode retrieves this case as prior context, closing the recurrence loop.
- Lessons learned embedded in vector knowledge base
- Retrieved automatically on similar future failures
- Knowledge compounds across investigations
- No manual knowledge management required
RCA AI Engine → G8D
When the RCA investigation concludes, a single action creates a linked G8D job. No copy-paste. No re-entry. The investigation output becomes the foundation of the corrective response record.
- Root cause narrative → D4 automatically
- Evidence citation map carried forward
- Action items from RCA → seed D5 corrective actions
- Same work order ID — single audit trail
Who Uses This
Built for the teams that own the problem
G8D is a team sport. The platform is designed for the people in the room — not just the person writing the report.
Quality Engineers & Quality Managers
Running a customer-facing 8D response under Controlled Shipping or SCAR — and needing a structured, audit-ready report that reflects what the investigation actually found, not a retroactive narrative.
Reliability & Failure Analysis Teams
Who have done the investigation work but spend days turning it into a formatted 8D document. G8D generates the report structure from the investigation — the engineering judgment stays with the team.
Operations & Plant Directors
Who need a consistent, repeatable problem-solving process across their plants — with a common format, full evidence traceability, and a record that satisfies OEM auditors and internal review boards.
