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 covers contracted suppliers and omits services procured on expense cards
- Fourth party dependencies not captured
- Inventory not reconciled, so exits and additions are missed
