A supplier that exists only in a contract folder is hard to review. The register is the list of who you rely on, how serious a failure would be, and whether the relationship is still being looked at.
What you need on the record
How supplier management helps describes the product.
- Who the supplier is, and the people you deal with.
- How critical they are, and whether they are still active.
- When the service was last reviewed, and when the next review falls.
- The contracts, NDAs, and other documents that belong to that supplier.
