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
- Inventory derived from procurement records only
- Mapping to business services missing
- End of life dates not tracked
- Ownership unclear for shared services
