Article Abstract

The consistent production of good quality products is the result of a complex interconnected sequence of events performed by a well knit team.Engineering and quality control make key inputs to provide manufacturing the opportunity to control their processes. Tolerances must be set, capabilities must be determined and these two figures must be compared. The operator must understand his instructions and/or specifications, have a means of determining if he is making product within these specifications, and be able to adjust the process before he produces unacceptable product.The quality function must monitor the system and communicate the results to the proper level of management. Management must respond to these result and take whatever action is necessary to correct weak areas.Check lists for manufacturing are a means to determine if all aspects of a manufacturing control plan are in place.The need for, and methods of, calculating process capabilities are presented. Capabilities are explained in relation to accepted norms which are actually process achievements, not capabilities. Once statistically valid process capabilities are determined the pre-control concept can be used to control the process without the need for recording, calculating, or plotting. (Records can be kept if required). The basis for the pre-control rules and their application are explained. The four benefits of X-R charts which are also benefits of pre-control are presented. Also, the six additional advantages of pre-control are presented.Joint responsibility charts are offered as a way of developing real teamwork between operators and management. The charts bring to life the slogan "We're in this thing together."Quality assurance check lists provide a way of being certain that all the quality elements are in place to assure product quality.
