Non-conformance record (NCR)

A non-conformance record (NCR) is a formal record used to document any product, process, service, or documentation that does not meet specified requirements. It captures what failed, how it was detected, immediate containment actions, evaluation, and the final disposition decision.

What a non-conformance record includes

While formats vary by organization and system, an NCR commonly includes:

• Identification details such as NCR number, date, originator, site, and department
• Reference information such as work order, batch/lot number, part or assembly number, serial number, and supplier or customer
• Description of the non-conformance, including what requirement was not met and how it was detected (inspection, test, operator report, customer complaint, audit)
• Severity or classification, such as minor/major/critical, product vs process, internal vs external, or safety-related
• Immediate containment actions, such as quarantine, line hold, blocking shipment, or temporary controls
• Investigation notes, including suspected causes, related incidents, and supporting evidence
• Material Review Board (MRB) or equivalent evaluation and disposition decision
• Linkage to corrective or preventive actions when a systemic issue is identified

Typical dispositions recorded on an NCR

The NCR is usually the primary record for how non-conforming material or work is handled. Disposition options often include:

• Use as is when the deviation is acceptable within defined criteria and properly authorized
• Rework to bring the item back into full compliance with the original requirements
• Repair to restore fit, form, or function under an approved concession or deviation from requirements
• Scrap when the non-conforming item cannot be used or repaired within acceptable limits
• Return to supplier when the non-conformance is attributed to an external provider and material is sent back

Operational role of NCRs in manufacturing systems

In regulated manufacturing environments, NCRs are often managed in a QMS or integrated across MES, ERP, and PLM. Operationally, they support:

• Traceability by linking non-conformances to specific serial numbers, batches, work orders, maintenance tasks, and suppliers
• Risk control by triggering containment actions, holds, and special inspections
• MRB workflow by routing affected items for technical review and disposition approval
• Cost tracking by associating scrap, rework, delays, and other cost of poor quality elements with specific events
• Trend and root cause analysis by providing structured data on types, locations, and causes of non-conformances
• Audit and investigation evidence by acting as a primary record set during internal audits, incident reviews, or regulator inquiries

Relationship to CAPA and other quality processes

An NCR documents the detection and handling of a specific non-conformity. It is related to, but distinct from:

• Corrective and preventive action (CAPA), which addresses underlying systemic causes. One or many NCRs may trigger a CAPA when a pattern or significant risk is identified.
• Supplier NCRs, which specifically capture non-conformances attributed to external suppliers and may feed into supplier scorecards and performance reviews.
• Deviations and concessions, which formally authorize use of non-conforming product under defined conditions. The NCR usually records any approved deviation and its scope.

Use in incident and safety investigations

In sectors such as aerospace and other safety-critical industries, non-conformance records are often a core evidence source for incident, field failure, or AOG investigations. Investigators examine NCR histories for affected parts, assemblies, and maintenance events to understand prior issues, repairs, or deviations. While NCRs can support root cause analysis and risk assessment, the presence or absence of NCRs does not on its own demonstrate compliance or non-compliance.

Common confusion

• NCR vs non-conformance: The non-conformance is the actual failure to meet a requirement; the NCR is the documented record of that event and its handling.
• NCR vs CAPA: An NCR captures a specific occurrence. CAPA is a broader process and record type used to address root causes and prevent recurrence across multiple events.
• NCR vs defect log or issue list: A defect or issue list may track problems informally. An NCR is a structured, traceable quality record, often controlled under a QMS and linked to other systems.
