Non-conformances are an unavoidable part of business operations. Whether a product fails to meet specification, a service falls short of requirements or a process deviates from its documented procedure, organisations need a structured way to identify, control and resolve these issues.
A well-designed Non-Conformance Procedure ensures problems are captured, investigated and resolved consistently — preventing recurrence and supporting continuous improvement. Read our complete guide on ISO 9001 Standard Operating Procedures to understand how non-conformance management connects to your wider quality management system.
What Is a Non-Conformance?
A non-conformance is any situation where a product, service or process fails to meet a defined requirement.
Non-conformances can be identified through:
- Internal quality inspections
- Customer complaints
- Internal audits
- Supplier assessments
- Process monitoring
- Employee observations
Every non-conformance should be recorded, investigated and resolved through a documented procedure. Our Quality Inspection SOP Template provides a structured framework for conducting consistent quality checks and capturing non-conformances at the point of inspection.
Why Non-Conformance Management Matters
Without a structured non-conformance process, organisations often experience:
- Repeated quality failures
- Increased customer complaints
- Higher rework and scrap costs
- Poor audit performance
- Compliance failures
- Loss of customer confidence
A documented procedure helps prevent these issues by creating one consistent process for managing all non-conformances. Read our complete guide on Corrective and Preventive Action (CAPA) for ISO 9001 compliance to understand how non-conformance management connects to your wider quality improvement framework.
The Non-Conformance Process
Identification and Recording
Non-conformances should be recorded as soon as they are identified. The record should include a description of the non-conformance, where and when it was identified, who identified it and what product, service or process is affected.
Containment
Where necessary, immediate containment actions should be taken to prevent non-conforming products or services from reaching customers or causing further impact.
Disposition
Non-conforming products or services should be dispositioned — decisions made about whether they should be reworked, repaired, accepted under concession, scrapped or returned to the supplier.
Root Cause Investigation
The root cause of the non-conformance should be investigated to understand why it occurred. Addressing root causes rather than symptoms prevents recurrence.
Corrective Action
Corrective actions should be planned and implemented to address the root cause and prevent the non-conformance from recurring. Our CAPA SOP Template provides the framework for investigating failures and implementing improvements.
Verification
Following corrective action implementation, the effectiveness of the actions should be verified to confirm the non-conformance has been resolved.
Closure and Records
Once verified, the non-conformance should be formally closed and all records retained. Read our complete guide on Document Control Procedures for ISO 9001 compliance to understand how non-conformance records should be managed and retained. Our Document Control SOP Template ensures non-conformance records are version-controlled, approved and retained correctly.
Non-Conformance and ISO 9001
ISO 9001:2015 Clause 8.7 requires organisations to ensure that outputs that do not conform to requirements are identified and controlled to prevent their unintended use or delivery.
A well-designed Non-Conformance Procedure helps organisations meet these requirements while building a culture of quality and continuous improvement.

Common Non-Conformance Mistakes
Many organisations experience recurring quality problems because they:
- Fail to record all non-conformances
- Address symptoms rather than root causes
- Do not verify the effectiveness of corrective actions
- Keep incomplete non-conformance records
- Allow non-conforming products to reach customers
- Treat non-conformance management as a paperwork exercise
Our Non-Conformance Management SOP Template provides a professionally written, ready-to-use procedure covering the complete non-conformance lifecycle.

Final Thoughts
Non-conformances are inevitable — but recurring non-conformances are not.
A well-designed Non-Conformance Procedure helps organisations capture problems quickly, investigate root causes thoroughly and implement effective corrective actions that prevent recurrence.
