Workflow

Flow 14 — Supplier corrective action and effectiveness

Turn one contained supplier NCR into an independently issued SCAR, retain immutable supplier-response revisions, verify systemic effectiveness and close with attributable evidence.

Overview

Inventory meaning

SCAR drafting, issue, supplier-response capture, decision, effectiveness and closure are zero-stock Quality facts. They never hold, release, move or adjust inventory and never approve, suspend or otherwise rewrite the supplier master.

Responsible roles

Quality Inspector → Supplier Quality Engineer → different QA Head → Supplier Quality Engineer → QA Head → Buyer / Procurement Manager / Auditor read-only

Process

1
Contained supplier NCR
Start from one exact supplier failure with proven containment.
Quality fact · Inventory unchanged
2
SCAR draft
Supplier Quality defines the problem, requested response and due date.
Request package · Inventory unchanged
3
Independent issue
QA verifies and records the manual delivery reference.
Issued Quality request · no supplier-status change
4
Versioned response
Capture supplier root cause and implemented systemic action.
Response evidence · Inventory unchanged
5
Independent decision
QA accepts or rejects; rejection preserves history and reopens response work.
Decision fact · Inventory unchanged
6
Effectiveness
QA tests sustained results against the accepted response.
Verification gate · Inventory unchanged
7
Closed
Retain closure acknowledgement while the parent NCR stays independently governed.
Closed SCAR · supplier/NCR unchanged

Role handoff

Quality Inspector → Supplier Quality Engineer → different QA Head → Supplier Quality Engineer → QA Head → Buyer / Procurement Manager / Auditor read-only

Detailed steps

1
As Quality Inspector, raise a SUPPLIER NCR with the registered vendor and record CLEAN evidence-backed containment. Confirm an OPEN or non-supplier NCR cannot start a SCAR.
2
As Supplier Quality Engineer, open Quality → Supplier corrective action, select the contained NCR and create the issue package with exact problem statement, requested containment/root cause/corrective action, response due date, supplier routing reference, classification and CLEAN evidence.
3
Submit the draft. Confirm Supplier Quality cannot issue it, then sign in as a different QA Head and independently record issue date, delivery method, delivery reference and decision note.
4
Return as Supplier Quality Engineer and capture the supplier representative, response reference, received/implementation dates, containment, structured root cause, contributing factors, correction, corrective/preventive action and CLEAN evidence.
5
Confirm the response capturer cannot decide their work. As QA Head, reject an incomplete response and verify it remains immutable as version 1, then accept a complete separately captured version 2.
6
Confirm Supplier Quality cannot verify their captured action. As QA Head, record an independent sustained-result method, observation, residual risk and CLEAN evidence; an ineffective result returns the SCAR to ISSUED for a new response version.
7
Close only after the latest review for the current accepted response is EFFECTIVE and a supplier closure/acknowledgement reference plus CLEAN evidence exists. Confirm the linked parent NCR does not close automatically.
8
As Buyer, Procurement Manager and Auditor, read the full chain and confirm every attempted mutation is denied, supplier AVL/registration state is unchanged and current stock plus stock ledger are unchanged.

Supplier Quality Engineer

Author the SCAR

Open /quality/supplier-actions

Select the contained supplier NCR and define the response package. A different QA Head issues it.

Exact field name	Requirement	Sample value A	How to use it
Contained supplier NCR	Select existing	`TRAIN-A-NCR-001`	Select the exact contained source NCR.
SCAR title	Required	`TRAIN-A thread-control corrective action`	Use a supplier-facing factual title.
Supplier contact / routing reference	Required	`TRAIN-A-SUPPLIER / Quality contact`	Use the approved contact route.
Response due date	Required	`2026-09-30`	Set the controlled supplier deadline.
Classification	Required	`RESTRICTED`	External handling must remain within policy.
Problem statement	Required	`Incoming batch failed approved thread-dimension criteria.`	Copy the approved problem boundary without adding unsupported claims.
Requested containment	Required	`Identify affected stock and stop further shipment pending review.`	State immediate supplier action expected.
Requested root-cause response	Required	`Provide method, verified cause and escape point.`	Define the required analysis.
Requested corrective action	Required	`Provide implemented systemic correction and effectiveness plan.`	Define closure evidence expected.

Expected result: The supplier response lifecycle is immutable and does not change supplier approval or stock by itself.

End state

One supplier action retains contained-NCR provenance, independent issue, rejected and accepted response versions, effectiveness and closure evidence while procurement, supplier approval, parent-NCR closure and inventory remain separately governed.
