Presentation on theme: "Six Sigma What is Six Sigma?"— Presentation transcript:
1 Six Sigma What is Six Sigma? Six Sigma is a results-oriented, project focused approach to quality.Six Sigma is a way of measuring and setting targets for reductions in product or service defects that is directly connected to customer requirements.
2 Six Sigma Targets Sigma Defects per Million 1 690,000 2 308,733 ,000,733,803,210
3 The Six Sigma ProcessDecision by senior management to engage in the Six Sigma processExecutive SeminarSelecting the “Champions”Special course for the “Champions”Process improvement teams
4 Black Belt Training Four or five weeks Each week of training is separated by three or four weeks during which teams apply the methods to the problemNew methods are introduced during each weekBlack Belts present their work to the instructors and other Black Belts candidates
5 Five Steps Approach (DMAIC) Define: problem statement (Y= f(X)), mission statement for the project, critical to quality (CTQ) parameters, quality function deployment (QFD)Measure: measurement system analysis for variables and attributes, cost of poor quality, process capability analysisAnalysis: root causes of the variation for Y, review of probability and statistics, non-normal distributions, estimation, hypothesis testing, regression and correlationImprove: find the optimum level for X using various methods, e.g. experimental designControl: having optimal levels for the X’s, the input factors and optimal Y establish the control
