How to Build a Supplier Evidence Matrix
Create a matrix that links supplier requirements to acceptable evidence, owners, review status, expiration and reusable source records.
Guide contents
Start with requirements
Rows should represent explicit requirements rather than folders or document names. This keeps the matrix tied to what must be proven.
Define acceptable evidence
For every requirement, document the evidence types, scope rules and review criteria that can satisfy it.
Allow one evidence item to support many requirements
A current certification, policy or declaration may support several buyer or internal requirements. Reuse should be visible and controlled.
Track gaps as work
Blank cells are not a workflow. Missing evidence should create an assigned action with a due date and resolution status.
