What events typically trigger an unscheduled SOP review?

• A. The calendar year schedule dictates timing.
• B. Routine reviews triggered by periodic cadence.
• C. Regulatory changes, process changes, major incidents, customer requirements, or audit findings.
• D. Sunspot activity affects operations.

Answer: (C)

Unscheduled SOP reviews are prompted by events that require updating procedures outside the planned cadence. When regulatory changes occur, procedures must reflect new laws or requirements immediately to stay compliant. If a process changes, the steps, controls, or responsibilities may need to be updated right away to keep operations safe and effective. Major incidents reveal gaps or failures in current procedures, signaling the need for quick revisions to prevent recurrence. Customer requirements can shift expectations or contractual obligations, demanding prompt alignment of documented procedures. Audit findings point to deficiencies that must be corrected without waiting for the next scheduled review.

The calendar-year schedule describes planned, regular timing rather than unexpected updates. Routine reviews triggered by periodic cadence are also scheduled changes, not unscheduled. Sunspot activity has no practical impact on SOP revision triggers.
