www.ketch.caIntroduction to Six SigmaApplying Statistical Analysis to Business Issueswww.ketch.caObjectives Understand Six Sigma Gain a high-level understanding of the tools methods and application of Six Sigma Learn the basic vocabulary of Six Sigma Understand the roles and responsibilities of Six Sigma practitioners Identify the benefits of Six Sigma as a business improvement methodologywww.ketch.caAgenda Introduction Methodology Roles and Responsibilities Why Six Sigma How to Implement Six Sigmawww.ketch.caIntroduction What Six Sigma means What Six Sigma is The concept of variation Performance and defectswww.ketch.caWhat Six Sigma Means Past definitions of quality focused on conformance to standards, as companies strived to create products and services that fell within certain specification limits. -Mikel Harry and Richard Schroederwww.ketch.caWhat Six Sigma Means ...this Six Sigma journey will change the paradigm from fixing products so they are perfect to fixing processes so that they produce nothing but perfection, or close to it. - Jack Welchwww.ketch.caWhat Six Sigma isMetricBenchmarkVisionPhilosophyMethodToolSymbolGoalValuewww.ketch.caThe Concept of VariationVariety may be the spice of life but, for customers, consistency is King!www.ketch.caThe Concept of VariationEvery repeatable process exhibits variationEvery repeatable process exhibits variationwww.ketch.caMeasuring VariationWe measure variation using standard deviation ()We measure variation using standard deviation ()Xwww.ketch.caPerformance and defectsReducing Variability Is The Essence of Six SigmaReducing Variability Is The Essence of Six SigmaDefects DefectsLSL USLXwww.ketch.caPerformance and Yield23456Defects per Million opportunitiesDefects per Million opportunities3 to 6 20,000 X Improvement...A True Quantum Leap3 to 6 20,000 X Improvement...A True Quantum Leap308,53766,8076,2102333.4YieldYield69.20%93.32%99.38%99.98%99.99%www.ketch.caPerformance in Context99.99966% Good (6 Sigma) 20,000 lost articles of mail per hour Unsafe drinking water for almost 15 minutes each day 5,000 incorrect surgical operations per week 340 Passengers with Misplaced Luggage every day 200,000 wrong drug prescriptions each year Seven articles lost per hour One unsafe minute every seven months 1.7 incorrect operations per week 6 Passengers with Misplaced luggage each month 68 wrong prescriptions per year99% Good (3.8 Sigma)www.ketch.caMethodologies Two distinctly different methodologies DMAICDefineMeasureAnalyzeImproveControlWhen a process needs to be improved DMADVDefineMeasureAnalyzeDesignVerifyWhen a process needs to be invented(aka.
