The concepts and techniques of Total Quality Control are the most important to be implemented before a successful Just-In-Time program can be realistically considered. This paper addresses the inter-relationships between J.I.T. and T.Q.C., the combined interface required with the engineering function, and application of operators and/or vendor quality responsibility.Just-In-Time application requires that 100% of the product conform to specifications established. Disruptions related to non-conformance cannot be tolerated in this environment, therefore, a program to minimize rejection occurrence must be put in place. The concept of Quality at the Source is explained and methodology for implementation is outlined, including Statistical Process Control and group problem solving techniques.The concept of Just-In-Time is explained in order to better emphasize the necessity of T.Q.C. and the idea that Quality Control is a total company responsibility.There are many companies today who still feel that it can be an easy step from their current environment into a J.I.T. environment. Unfortunately, some make the attempt before they are ready and end up with internal chaos and/or alienated suppliers. There are no shortcuts as far as the basic disciplines are concerned. Chief among these is the quality issue, which must be addressed before the J.I.T. concept can be effectively executed.Figures 1-1, 1-2, and 1-3 graphically illustrate the dramatic gains in market share that can be achieved through improved quality levels and lower inventory costs.
