How is 'nonconformity' defined in ISO 9001?

The definition of 'nonconformity' in ISO 9001 focuses specifically on a failure to meet a requirement specified within the Quality Management System (QMS). This could involve any situation where processes, procedures, or products do not adhere to established standards or requirements set by the organization itself or regulatory bodies.

When a nonconformity is identified, it signals a need for corrective action to align the performance back with the established requirements. This concept is critical in the continuous improvement processes inherent in ISO 9001, as it allows organizations to assess and enhance their management systems effectively.

In contrast, other options entail different meanings. A deviation from industry standards does not specifically relate to the internal requirements set by an organization's QMS, while suggestions for improvement from auditors or customer complaints might indicate areas requiring attention but do not directly define nonconformity within the ISO 9001 framework.
