Use the checklist to prepare a remote or on-site supplier audit. Evidence should be sampled through records and trace exercises, not accepted from policy statements alone.
Select a recently released lot and trace it backwards through testing, production and incoming material. Then select an incoming lot and trace it forwards to every affected finished lot. This exposes gaps that a clause-by-clause document review may miss.
