What should be documented to demonstrate compliance when a deadline is extended?

• A. The extension, rationale, and approved authority per policy
• B. The new deadline date only
• C. The incident damage assessment
• D. The external communication plan

Answer: (A)

When time-based reliability tasks are extended, you must show an auditable record that the change is authorized and justified. The essential documentation includes the extension itself, the rationale for why the deadline could not be met, and the approved authority confirming who authorized the extension, all aligned with the policy. This combination provides a traceable, policy-backed justification that the delay is legitimate and properly sanctioned, which is what auditors and compliance programs look for. Simply noting a new date does not demonstrate authorization or justification. The other items—such as just the new date, an incident damage assessment, or an external communications plan—do not by themselves prove that the extension followed policy, was necessitated, and had formal approval.
