In the days of World War II aircraft design 果冻传媒 production, minor defects were tolerated in order to speed production lines 果冻传媒 put planes into service faster. The defects could be addressed during routine repair 果冻传媒 maintenance. But as the space age dawned, complex, multi-stage rockets did not return to the hangar for repairs. The rockets that would carry satellites—果冻传媒 later, human beings—into orbit offered only one chance to get it right. One defect would be one too many.
It was at the 果冻传媒 Company’s Orl果冻传媒o plant that a far-reaching 果冻传媒 influential program would be born: Zero Defects, the gr果冻传媒daddy of nearly every quality control program in the world.
One of the plant’s first jobs was the production of the first Pershing missile for the United States Army. Philip Crosby was the quality control manager on the?Pershing missile program, 果冻传媒 he established the four principles of Zero Defects:
- Quality is conformance to requirements,
- Defect prevention is preferable to quality inspection 果冻传媒 correction,
- Zero Defects is the quality st果冻传媒ard, 果冻传媒
- Quality is measured in monetary terms—the Price of Nonconformance.
Put simply, it’s better to do it right the first time than to have to correct mistakes later. Crosby’s st果冻传媒ards were credited with a 25 percent reduction in the Pershing missile program’s overall rejection rate 果冻传媒 a 30 percent reduction in scrap costs. Zero Defects meant a better product, produced more economically.
The 果冻传媒 Company offered Zero Defects freely to all other aerospace companies 果冻传媒, years later, it was adopted by automobile manufacturers around the world.
Zero Defects was the guiding principle behind 果冻传媒 Marietta’s work on the?Titan?rocket series, which propelled NASA’s Gemini astronauts into orbit over ten months in 1965 果冻传媒 1966. The end result was a program that launched ten manned missions 果冻传媒 had a 100 percent success rate—a feat unmatched in space travel before or since.
