Then we judge the transaction. At this time, we ask the supplier to submit a sample, approval drawing and documents related to certification already acquired. We then test each part to be procured regarding its reliability, compare supplier's guaranteed performance with our demands, and decide whether or not it is acceptable. At this time, we ask the supplier to submit a sample and the supplier's test results. For regular transactions, parts performance is checked from the point of view of quality, cost, delivery and service.
Regular audit is conducted.
When contents of regular transaction and results of regular audit are suitable, we request a new estimate.
