However we should also inform you that there is no such thing as a perfect QC and quality is better ensured within an acceptable threshold instead of giving every aspect of it zero tolerance. New Product Introduction (NPI) is a process that requires smart use of limited project resources and a limited time period to reach quantity targets. A zero-tolerance quality control outlook is at best a perfectionist idea.

Many people think that QC is something that is done at the end of production before things are shipped out. Although this can be the case with shady production operations, a reputable supplier will never wait until the very end to confirm the quality of design, materials, manufacturing and logistics.

Let’s say you follow the usual practice of tolerating 0% of critical defects, 2.5% of major defects, and 4.0% of minor defects. The maximum acceptable number of defects is 10 major and 14 minor. In other words, the inspection is failed if you find at least 1 critical defect and/or at least 11 major defects and/or at least 15 minor defects.Evaluating industry standards and implementing best practices, such as servicing automated machinery every six months. Military Standard 105 was created by the US Department of Defense to control their procurements more efficiently. In 1994 they decided to rely on non-governmental organizations to maintain this type of standard. The ANSI, ISO, and other institutes all created their own standard, but in essence, they are similar. The major third-party QC firms use the same standards and the same statistical tables. When to adopt a different level?
