The questions are:
Do you have a "parts return to stores" process?
Does it make returns easy to prevent "squirreling" of parts on the shop floor?
Does it insure quality parts are kept in stores and damaged parts are disposed of?
In the end we want to prevent spoilage and insure that the part and the turkey provides maximum health and reliability and not infant mortality. This way of thinking will get us a lower cost level of reliability now.
