Article Abstract

The problem before us is "How do we survive in the marketplace in tomorrow's environment?" Survival is dependent upon establishing an attitude for never-ending improvement of quality and productivity. To this end, we must unite with our suppliers to form a long-term commitment resulting in free flow of information, effective utilization of all resources and reduced costs. The Japanese have shown us that Statistical Process Control is one major way of controlling scrap and waste. Many of our suppliers are small and do not have the expertise or cannot afford the expertise to initiate Statistical Process Control and Statistical Methods (SPC/Methods).There have been many excellent books, articles, papers, seminars, video tapes, discussions and university-level courses describing statistical methods and SPC. Comparatively very little has been written on ways to help your suppliers implement SPC and methods. This paper will explore the various methodologies and approaches that can be used to assist them in becoming aware of the need of using statistics to make their decisions.

A look into our past errors must be made in order to build our future. The history of the use of statistical methods will be reviewed in the automotive and aerospace industries from the 1940's to the present. From the past, we have learned that leading by example is a very persuasive method. The attitude of our company's management toward SPC is the key to our supplier's attitude. Five prerequisites must be in place or are being implemented prior to your requiring SPC/methods at your suppliers. All of this will be addressed in the paper.

The main text describes the various methodologies and approaches that can be tailored into a program that best fulfills the needs of you and your supplier base. Success is evident in certain industries where contractually mandatory statements (i.e., Ford Motor Company's Q101) are made and where everyone who wants to do business must comply. Other methods that are more normal and applicable are the Problem Resolution and Problem Prevention Methods. These will be discussed in detail. To support these two basic approaches, other topics will be addressed; they are as follows: management awareness, large-scale seminars, pilot programs, team selection, training, written plans and data collection.

Armed with the above information, we will be able to create the environment to implement never-ending improvement of quality and productivity.
