A total buyer's Quality Assurance (QA) program includes the following activities: development of quality and reliability criteria, quality and reliability analyses prior to purchase, sampling of the products at the site of manufacture and monitoring the product in actual field usage. The purpose of the program is to insure that products purchased are reliable and to minimize the cost of poor quality to the buyer.QA activities generate data that are used to identify quality problems. One method of lowering the cost of doing quality assurance is through more thorough analysis of data collected. We propose an evolutionary approach of building three levels of expert systems. The first stage of this development is expert software to help the quality engineer pick out the quality problems and determine the source of the problem. Stage two is an expert system that performs detailed analysis on the vast amounts of data looking for quality problems hidden from the standard analysis routines. The final stage is an integrated system that uses all available data to report on the overall quality effort.
