Supplier risk tiering uses evidence to decide where qualification and monitoring effort are most needed. Public information can identify questions to investigate, but it rarely proves that a particular order is ready for release.
Combine the importance of the supplied item with verified company, facility and capability information. Check the date and scope of public records. Record missing evidence separately from a confirmed failure so the assessment remains fair and interpretable.
Use the tier to determine the next evidence request, review or contingency action. Update it when new information arrives or dependencies change. Keep the final purchasing decision connected to the product and order requirements.
