WHAT IS SIX SIGMA ? Measure of how well a process is performing- Six Sigma process produces 3.4 defects permillion opportunities- Most companies are at 3-4 sigma level Philosophy of reducing defects so we can improvecustomer satisfaction and reduce costs Business Strategy that increases processperformance resulting in enhanced customer satisfactionand improved bottom line ($$).
SIX SIGMAIt is a Philosophy– Anything less than ideal is anopportunity for improvement– Defects costs money– Understanding processes andimproving them is the mostefficient way to achieve lastingresultsIt is a Process– To achieve this level ofperformance you need to:Define, Measure, Analyse, Improve and ControlIt is Statistics– 6 Sigma processes willproduce less than 3.4defects per millionopportunities
