【正文】 g defects .27% bad vs. % good ? Change unit of measure 2,700 PPM vs. .27% bad What is six sigma It is a culture change for a plete anization That’s: – Individually driven but involves everyone – Continuous process – Consistent throughout the anization – Measurement driven Based on the premise “ Everyone wants to do the best job they can It is not a numbers game Was the meeting necessary? Was ther an objective municated in advance? Was time used effectively? Was there adequate advance information to help me understand and contribute to the objective?

Tough goal setting(reach out!!!) ? Provide the required education ? Spread the success story ? Shared the rewards with those that that contributed 10 year journey ?? 1990 through 20xx Quality ? Through defect elimination we have eliminated % of in proces defects (?) ? COPQ (cost of poor quality) reduced 84% on a per unit basis ? Manufacturing cost saving cumulative saving over $ billion ? Product reliability MTBF . . . increased 510 fold Financial ? Sales up ， $ billion anaverage pounded growth rate of % per year ? Employee productivity increased 408% 169。 institutionalize Problem splve analyze Defect analysis is done by the appropriate anization: Marketing Engineering Manufacturing Materials service etc… Process step 1 Process step 2 Process step 3 Record defects Trend chart/Goal Record defects Record defects Record defects Record defects supplier customer Institutionalize solutions Continuous improvement meyhodology action name date time 100 Pareto analysis/ root cause indetification measure Results amp。therefore… Decreases “Manufacturing” cost Cost/Quality Six sigma has shown that The highest quality producer is The lowest Cost producer ? TDU is the best measure of the over all quality of the process – TDU is the independent variable – Process yields are dependent upon TDU The mon metric: Total defects per unit(TDU) Defining a unit A “unit” may be as diverse as a: ? Piece of equipment ? Line of software ? Order ? Technical manual ? Medical claim ? Wire transfer ? Hour of labor ? Customer contact Anything that is measurable amp。 adopted 1986 ?
