governing documentDocuments that govern the control

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
- supplier list held by procurement with no link to systems
- sub-tier suppliers entirely unknown
- inventory cannot answer which systems a given supplier touches
