Supplier Evidence File
The supplier promises spare parts for after-sales service but does not say where parts are stored. Turn the situation into a practical buyer record.
A warranty spare part storage file should begin with the decision that could fail. In this case, the supplier promises spare parts for after-sales service but does not say where parts are stored. The buyer is not collecting paperwork for its own sake. The buyer needs to decide whether to pay, approve, ship, return, replace, repair, or escalate.
When the supplier changes a material, site, process, subcontractor, or test document, record the old and new facts. The change resets the question the original approval answered. Record the result beside the current order. The named scope is China supplier warranty spare part storage check.
