The results of these projects are incorporated into running the day to day business. 16 8. 3 levels of anization 1).

Preface 1. 1980 USA face to Japan’ s petition Japan’ s weapon: quality 2. 1985: Motorola’ s engineer Bill Smith reported,” if a product was found,defective and corrected during the production process,other defects were bound to be missed and found later by the customer during early use of the product, However,when the product was MFG errorfree,it rarely failed during early use by the customer.” 3. 1987 Motorola phase in 6 sigma 4. 1989 Motorola win the Malcolm Baldrige National Quality Award. 5. 1991 Allied Signal phase in 6 sigma, Saving BUSD/YR Productivity :6% up Profit : improved 13% 6. 1996 GE phase in 6 sigma due to Allied Signal’ s result.
