A nonconformity is the non-fulfillment of an ISO standard requirement, identified through objective evidence during an audit.
According to ISO 9000:2015, a nonconformity is the non-fulfillment of a requirement. In ISO audit context, it is classified as major (systemic failure or absence of a required process) or minor (isolated deviation that does not compromise system effectiveness).
A major nonconformity can prevent or suspend certification. A minor one requires corrective action but does not block the certificate.
Every nonconformity requires root cause analysis and documented corrective action eliminating the cause, not just the symptom.
Must be supported by verifiable data: documents, records, interviews or process sampling.
Zero. Every major nonconformity must be resolved with evidence of effective corrective action before the certification body issues the certificate.
If it persists at the next surveillance audit, it can be escalated to major. Accumulation of unresolved minors can also indicate a systemic failure.
No. An observation (or improvement opportunity) is a finding that does not breach a requirement but flags an area that could deteriorate. It does not require formal corrective action.
