If a requirement states 'no later than X hours after Y' and action does not begin until after Y due to constraints, what should be done?

• A. Extend the window to fit the delay.
• B. Ignore the delay and proceed.
• C. Document the delay with justification, take action as soon as possible, and follow incident reporting and escalation procedures.
• D. Reassign the task to another team without reporting.

Answer: (C)

When a requirement is stated as no later than X hours after Y, the aim is timely action with an auditable trail. If constraints prevent starting on time, the correct approach is to document the delay with a clear justification, take the action as soon as possible, and follow the incident reporting and escalation procedures. This keeps accountability and traceability, helps management understand what happened, and ensures necessary resources or priorities can be adjusted through proper channels.

Extending the window would effectively change the requirement, which isn’t permissible. Ignoring the delay ignores safety and reliability commitments. Reassigning without reporting bypasses the required escalation process.
