You have been nominated as audit team leader for the second recertification to ISO 14001...

The correct answers are A and B.

The nonconformity concerns ABC’s failure to communicate relevant environmental requirements to an external provider. This relates mainly to ISO 14001:2015 Clause 8.1 — Operational planning and control, which requires the organisation to ensure that outsourced processes are controlled or influenced and that relevant environmental requirements are communicated to external providers.

A. We revised the contract to add the relevant environmental requirements — Correct

This is the immediate correction. The specific contract that caused the nonconformity has been amended so that the maintenance provider receives the relevant environmental requirements.

B. We revised the procurement process — Correct

This is the stronger systemic corrective action. Revising the procurement process helps prevent recurrence by ensuring future contracts or purchasing arrangements include relevant environmental requirements before external providers are approved or work begins.

The other options are less suitable:

C may be useful background work, but it does not directly correct the failure to communicate requirements.

D is only a future discussion, not a completed corrective action.

E may help verify effectiveness later, but it is not the corrective action itself.

F may support implementation, but training alone is weaker than changing the process that allowed the omission.

Therefore, the best corrective actions are A and B.
