Confirm supplier identity and scope

Start with legal entity, operating locations, products or services supplied, ownership context and the business relationship being reviewed.

Apply risk-based requirements

Use geography, category, spend, product, customer and regulatory exposure to determine which questions and evidence are appropriate.

Separate evidence from assertions

Supplier responses should identify the documents, records or external sources that support material claims.

Close the review with a decision

The output should be approved, conditionally approved, escalated or rejected with unresolved findings assigned for remediation.
