Look for evidence, not prepared answers
A useful audit follows records and product flow. Compare written procedures with what operators actually do, inspect examples from recent production and ask how exceptions are handled. The objective is to understand whether the supplier can deliver a repeatable product, not simply whether the workshop looks busy.
