If a plan is modified after initial approval, what should be documented?

• A. A modification note and updated version only
• B. A modification note and re-verification/sign-off
• C. A modification note, updated version, and re-verification/sign-off
• D. An email to the team describing changes

Answer: (C)

When a plan is modified after it’s been approved, you need a formal change-control record that creates a clear, auditable trail. The modification note explains what changed, why it changed, when, and who initiated the change. The updated version ensures the active document actually reflects the modification and can be tracked through version control. Re-verification or sign-off by the appropriate approver(s) confirms the changes have been reviewed and formally approved. Together, these elements maintain proper governance, ensure everyone uses the current plan, and provide traceability for future audits. An email describing changes might be helpful, but it doesn’t replace formal documentation or an approved revision.
