This paper is a description of requirements for certification of a piecepart via process qualification. Unlike the many articles, books, lectures, etc. Telling American industry that they must implement process control, be innovative, apply statistics, use control charts, etc. Xerox tells how. Xerox states exactly what a supplier must do, then we state how to do it, and finally, we support the how with training. This paper is a complete description of what our suppliers must do to survive in the business environment of the 80's. We do not say implement process control and then retreat to our ivory tower as do so many. We say do it but then we hang in and show the vendor how to do it. Each supplier is given all the tools and shown as many times as necessary how to use the tools. It is this complete package that leads to quality product and economic success. The system that Xerox implements is used throughout the world. All suppliers regardless of location use the same criteria and even the same forms, modified for the language of their country. This permits the use of Supplier Quality Assurance Engineers from local regions rather than from a particular Xerox plant. The requirements remain constant and qualified product can be shipped to any Xerox facility in the world without inspection by Xerox. This concept of Process Qualification and hence part certification permits successful implementation of Central Commodities Management, Direct Shipping, and Just-In-Time planning.
