A Field Method for Factory Audits: From Documents to the Line
A useful audit is not a tour. It is a structured check of capability, process and risk boundaries.

Define the question first
Set the focus by product risk: electronics need testing and certification checks; furniture needs material and packing checks; apparel needs pattern, fabric and capacity checks.
Walk four zones
Follow incoming materials, production, inspection and finished goods. Look for continuity in records, treatment of exceptions, isolation of rework and whether equipment matches the quoted capability.
Turn findings into action
End with a corrective-action list: evidence, owner, due date and verification method. An improvement that can be checked becomes part of supplier capability.
Conclusion
An audit does not replace sample testing or pre-shipment inspection. It does reveal communication, capacity and record-keeping risks earlier.
Sourcing information earns its value when it is verified, compared and turned into a decision.
