10.2 Nonconformity and corrective action

If a nonconformity arises, the organization must respond to it and, as applicable, act to control and correct it and handle what follows from it; evaluate whether action is needed to remove its causes so it does not recur or arise elsewhere, by reviewing it, finding its causes and checking whether similar nonconformities exist or could occur; implement any action needed; review how effective the corrective action was; and change the ISMS if necessary. Corrective actions must suit the effects of the nonconformities. Documented information must be available as evidence of the nature of nonconformities, the actions taken and the results of corrective action.

Clauses 4 to 10 are the management-system requirements: none of them can be excluded when an organisation claims conformity. The 93 Annex A controls are a reference set: one may be excluded with a justification in the Statement of Applicability. Certification bodies assess conformity; the evidence lists here are what auditors commonly ask for, not a list the standard prescribes.
