First move
This control is evidenced by people and documents, not systems. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date. Do not try to automate it.
Common gaps auditors find
- Generator started monthly off load so genuine capacity is never proven
- UPS batteries beyond service life with no capacity measurement on file
- Distributors inspected for tidiness but not for signs of tampering or undocumented patching
- Resilience lost because both rack feeds trace back to one distribution board
