Six Sigma Producibility Analysis and Process CharacterizationAddison-Wesley, 1992 - Всего страниц: 160 This definitive book provides the core measurement tools that Motorola, winner of the 1988 Malcolm Baldridge National Quality Award, uses to consistently produce high-calibre products as part of their drive to attain Six Sigma Quality--only 3.4 defects per million opportunities for error. Producibility Analysis and Process Characterization are groundbreaking engineering and statistical techniques for determining the probability that each manufacturing process will always yield identical products with zero defects. |
