According to the ISO/IEC 27001:2022 Lead Auditor (Information Security Management Systems) course, the following actions should be taken when a nonconformity identified for completion before the follow-up audit is still outstanding:
* A. Report the failure to address the corrective action for the outstanding nonconformity to the organisation's top management. This is part of the auditor's responsibility to communicate the audit results and ensure that the audit objectives are met12.
* C. If the delay is justified agree on a revised date for clearing the nonconformity with the auditee/audit client. This is part of the auditor's responsibility to verify the effectiveness of the corrective actions taken by the auditee and to close the nonconformity when the evidence is satisfactory12.
* E. Decide whether the delay in addressing the nonconformity is justified. This is part of the auditor's responsibility to evaluate the evidence presented by the auditee and to use professional judgement and objectivity to determine the validity of the reasons for the delay12.
* G. Note the nonconformity is still outstanding and follow audit trails to determine why. This is part of the auditor's responsibility to collect and verify audit evidence and to identify the root causes of the nonconformity12.
