    The development of quality standards currently used in industry was driven by a number of forces. US Government initiated quality programs such as MIL-Q-9858 and MIL-I-45208 were a response to the poor quality of ordnance during World War II. The North American automotive industry developed its own distinct quality program and supplier requirements in an effort to compete with the public perceptio... View full abstract»
