I'm curious. Are you looking as a customer for criteria to allow a supplier to ship directly to stock? (Some systems, like Toyota, have established criteria for product to go directly to the production line with NO PROVISION for even temporary stocking.)
Are you looking as a supplier to convince a customer of the value of your own QMS to the point the customer can save the soft costs of incoming inspection, temporary quarantine, internal movement of product, etc. for products you ship in? (I was successful in getting several contracts for products at higher prices than competitors because I was able to demonstrate the net "product in place" cost would be less doing business with my organization.)
