Purchasing Reliability

The contributing responsibility and a system for controlling component reliability as part of the procurement function are discussed. The system, which is particularly applicable to large-scale procurement, consists of three major controls: 1) Component Vendor Approval Procedure??a tool for obtaining and documenting bona fide sources capable of supplying components to specified time and quality requirements. 2) Vendor Delivery Performance??a purchasing control for maintaining and upgrading performance from selected vendors. 3) Vendor Quality Rating??a quality control tool to aid purchasing in maintaining and upgrading quality of products from selected vendors.
