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
- Generators started monthly without load, so failure under real demand is untested
- Battery capacity assumed at nameplate with no measurement of actual remaining runtime
- Cooling excluded from resilience planning even though its failure takes the facility out fastest
- Fuel contracts in place with no priority guarantee, which matters in a regional event
