First move
Start with the 1 of 4 artefacts that already live in a system (Document repository); keep the periodic reviews but log each one as a dated record with a named reviewer.
Common gaps auditors find
- Redundant equipment in the same room or same power and cooling domain
- Redundancy assumed from a supplier claim and never tested
- No definition of which equipment is business-critical
