The reliability of a well-designed product is usually degraded to some extent in manufacturing it. A low but finite number of defects in both parts and workmanship is generally considered normal in manufacturing processes involving people and machines. To sustain the level of reliability inherent in the design, however, these defects must be discovered and corrected before the product leaves the factory. Otherwise, they will show up as product failures in service use with possibly serious military consequences and always with undesirable cost impact. Further, the discovery and correction of defects in the factory contributes significantly to the manufacturers production costs, as do field returns for correction of defects under contract requirements and warranties. Both the Navy and its suppliers, therefore, have a vital interest in the most efficient and effective means for the earliest elimination of defects. Most Navy programs acquiring electronic devices and systems traditionally have depended on the final acceptance test to catch manufacturing defects. They have relied on this screen as a sufficient incentive to the manufacturer for the inclusion of additional pre-acceptance test screens of many different forms in his production operation. Some contracts have called out specific pre-acceptance tests e.g., burn-in for the primary or ancillary purpose of defect detection. For a variety of reasons, both technical and contractual, the vast majority of electronic devices and systems delivered to the Navy continue to contain manufacturing defects in parts and workmanship which could have and should have been discovered and eliminated in the factory.
