1.Purpose
To make sure nonconforming product is identified, contained and dispositioned consistently, so defective product does not reach the customer and the root cause is addressed to prevent recurrence.
2.Scope
Applies to product identified as nonconforming during inspection, in production, or after a customer complaint. Routine sampling and inspection activity itself is covered by the quality inspection SOP.
Definitions
- NCR
- Nonconformance report. The record documenting a nonconforming condition, its containment and its disposition.
- Material review board (MRB)
- The cross-functional group that decides how nonconforming product is dispositioned.
- Disposition
- The decision made for nonconforming product: rework, scrap, use-as-is, or return to supplier.
- Containment
- Action taken to stop suspect nonconforming product from moving further into production or to the customer.
3.Responsibilities
- Quality Inspector
- Identifies nonconforming product, tags and segregates it, and opens the NCR.
- Production Operator
- Stops producing suspect product when notified and assists in checking upstream and downstream product.
- Material Review Board
- Reviews the NCR, determines the root cause, and decides the disposition of the nonconforming product.
- Production Supervisor
- Coordinates containment on the floor and ensures corrective action is communicated to the shift.

4.Materials and PPE
Materials, tools and systems
- โNonconformance report (NCR) log or QMS
- โQuarantine area and tags
- โRoot cause analysis form
- โMaterial review board meeting record
- โSpecification and control plan for the affected part
Personal protective equipment
- โSafety glasses
- โGloves appropriate to the product material
5.Procedure
- 5.1
Stop production of suspect product
Production OperatorInspector or operator who identifies a suspect nonconforming condition stops production of the affected part immediately and notifies the production supervisor.
- 5.2
Tag and segregate the nonconforming material
Quality InspectorInspector tags the nonconforming product clearly and moves it to the quarantine area, physically separated from conforming product.
Warning: Do not leave tagged nonconforming product mixed with conforming stock, even temporarily.
- 5.3
Open the nonconformance report
Quality InspectorInspector opens an NCR in the log or QMS describing the part, quantity, defect found, and where and when it was discovered.
- 5.4
Notify quality and production supervisor
Quality InspectorInspector notifies the quality manager and production supervisor of the nonconformance so containment can be coordinated across the affected shift or area.
- 5.5
Contain upstream and downstream product
Production SupervisorInspector and operator check product made before and after the suspect part was found, including any already moved to the next process or into finished goods, and quarantine anything at risk.
Checkpoint: All product made between the last known good check and the point of discovery is located and checked.
- 5.6
Perform root cause analysis
Quality InspectorQuality inspector leads a root cause analysis using the NCR details, process records and, where relevant, the operator's account of the process conditions.
- 5.7
Convene the material review board
Material Review BoardMaterial review board reviews the NCR, root cause findings and quantity affected, and decides whether to rework, scrap, use-as-is or return the product to the supplier.
Checkpoint: Disposition decision is documented on the NCR with the reasoning before any product is released or scrapped.
- 5.8
Execute the disposition
Quality InspectorThe assigned team executes the disposition decided by the material review board, such as performing the rework, scrapping the material, or returning it to the supplier with documentation.
- 5.9
Verify reworked product meets specification
Quality InspectorInspector re-inspects any reworked product against the full specification before it is released back into the production flow.
- 5.10
Update and close the NCR
Quality InspectorQuality inspector updates the NCR with the final disposition, quantities reworked or scrapped, and closes the record once all actions are complete.
- 5.11
Communicate corrective action to production
Production SupervisorProduction supervisor communicates the root cause and any process change to the affected shift so the same nonconformance is less likely to recur.
- 5.12
Track nonconformance trends
Material Review BoardQuality manager reviews NCR trends by part number, defect type and root cause monthly to identify recurring issues needing a broader corrective action.
6.Quality checks
- โEvery nonconforming lot has a documented containment check of upstream and downstream product.
- โNo disposition is executed before the material review board decision is documented on the NCR.
- โReworked product is re-inspected against the full specification before release.
- โNCR trends are reviewed monthly for recurring root causes.
7.Records
- โNonconformance reports (NCRs)
- โRoot cause analysis documentation
- โMaterial review board decisions
- โRework, scrap and supplier return records
8.KPIs
- โNumber of NCRs opened per period
- โAverage time to close an NCR
- โPercentage of nonconformances with a completed root cause analysis
- โRepeat nonconformances by part number or root cause
9.Common mistakes
- โReworking product before the material review board decides the disposition.
- โNot checking downstream product already moved past the point of discovery.
- โClosing an NCR without a documented root cause.
- โLeaving quarantined material unlabeled or in a shared staging area.
- โSkipping re-inspection of reworked product before release.
