Terms and definitions
Changed in ISO 9001:2026
Twenty core terms are defined inside clause 3 itself (ISO 9000 stays the full vocabulary); 'conformance' is deprecated in favour of 'conformity'; 'opportunity' remains undefined. Annex A.2 clarifies the words the requirements hinge on.
Checked against the published text on 27 September 2026.
Plain-language summary
Confirmed in the published text: clause 3 now carries twenty core management-system terms of its own — organisation, interested party, top management, management system and quality management system, policy and quality policy, objective and quality objective, risk, process, competence, documented information, performance, continual improvement, effectiveness, requirement, conformity, nonconformity, corrective action, audit, measurement and monitoring — with ISO 9000 remaining the normative vocabulary behind them. The 2015 edition defined nothing locally. One deliberate gap matters: 'opportunity', which now carries its own sub-clause in 6.1, is still not defined in either document. Annex A.2 adds working clarifications of six word pairs the requirements turn on — appropriate versus applicable, consider versus take into account, continual versus continuous, what 'ensure' means, the two documented-information phrasings, and 'strategic direction'.
What the clause is really asking
Nothing new is required of you — this is a convenience change. But it quietly asks you to know which definitions now sit in the standard you are reading, and to close the 'opportunity' gap yourself: decide what an opportunity means in your organisation and use that meaning consistently.
What auditors look for
No findings arise from clause 3 directly. Where it shows up is in argument-settling: an auditor will use the in-standard definitions as the reference point in any disagreement about what 'process', 'risk' or 'documented information' means. On 'opportunity', expect a competent auditor to probe whether your treatment of opportunities is coherent and genuine — they cannot hold you to a definition that does not exist, but they can test whether yours is real or a column filled in to satisfy clause 6.1.
Typical evidence
A working definition of 'opportunity' written into your risk-and-opportunity procedure (QP-005-style) and applied consistently in the register; internal-auditor training material updated to reference the in-standard definitions.
How to comply — recommendations
When the standard publishes, skim clause 3 and note which terms are defined locally versus in ISO 9000. Use the local set when training internal auditors and new quality staff. Write one sentence into your risk-and-opportunity process defining what your organisation treats as an opportunity — an efficiency gain, a new capability or market, a chance to remove a recurring problem at its root — and make the register reflect it.
Common nonconformities
None directly — but incoherent 'opportunity' entries in the 6.1 register (vague, never actioned, indistinguishable from risks) become easier findings once 6.1 is restructured.
