Wong,Scope of Module,What is Six Sigma,Why the need for Six Sigma,How to apply Six Sigma,2,What is Six Sigma?,Six Sigma,is a comprehensive and flexible system for achieving,sustaining and maximizing business success.It is uniquely driven by close understanding of customer needs,disciplined use of facts,data and statistical analysis,with diligent attention to managing,improving and reinventing business processes.,Peter S Pande,Robert P Neuman,Roland R Cavanagh,The Six Sigma Way,(McGraw Hill,2000),3,Six Sigma,Is Three Things,A statistical measurement,A business strategy,A philosophy,4,1)Six Sigma,A Statistical Measurement,It provides a quantitative performance assessment of our products,services and processes.,It allows for comparisons against other similar or dissimilar products,services and processes.,It provides feedback on how far ahead or behind we are.,Six Sigma helps to establish our course and to gauge our pace in the race for total customer satisfaction.,5,Six Sigma A business strategy,Improved Sigma-Rating of Process,Improved Product or Process Quality,Reduced Cost of Operations,Greater Customer Satisfaction,6,Cost Of Poor Quality(COPQ),Traditional Quality Costs,(tangible),Lost Opportunity,Hidden Factory,Additional Costs of Poor Quality,(intangible),(Difficult or impossible to measure),COPQ is a function of Sigma

eliminated),Improved process capability,Sigma rating goes up,9,Quality Breakthrough,Time,Reject Rate,Historical Level(,0,),Natural Variation under,0,(3,0,),Special Variation,Optimum Level(,1,),Natural Variation under,1,(3,1,),10,Why needs of Six Sigma?,The goal of,Six Sigma,is not to achieve six sigma levels of quality(i.e.3.4 dpmo).,6s,Defects,Six Sigma,is about,improving profitability,;improved quality and efficiency are immediate by-products.,11,Six Sigma aggressive goal,Sigma is a statistical unit of measure that reflects process capability.The sigma scale of measure is perfectly correlated to such characteristics as defects-per-unit,parts-per million defective,and the probability of a failure/error.,PPM,Process,Capability,Defects per,Million Opp.,12,Six Sigma Process,m,Point

Sigma?,Unlike conventional improvement programs which focuses on improving the defects on the“output”,Six Sigma,focuses on the“process”that creates or eliminates the defects.,Six Sigma,seeks to reduce variability in a process by means of a systematic approach called the,Breakthrough Strategy,.,Process,Input,Output,16,Six Sigma approach,Identify the Customers Need,Center around the Target,Reduce Variation,Reduce Defects,17,Focus of Six Sigma?,Process,Input,Output,The output(Y)is perceived as a function of the input(X).,18,Breakthrough Strategy,Breakthrough,Strategy,Characterization,Optimization,Measure,Analyze,Improve,Control,Define,Realize,19,Define,The,Define,phase sets the stage for a successful,Six Sigma,project by addressing the following questions:,What is the,problem,of our focus?,Whats our,goal,?And by when?,Whos the,customer,impacted?,What are the,CTXs,in-concern?,Whats the,process,under investigation?,20,Project Definition,Improve time to market for all products,Lead the industry in key technologies,Create world-class manufacturing processes,Develop strategic supplier relationships,Provide best-in-class product and process quality,Develop strategic relationships with key customers,Become an employer of choice,21,Baseline Metric Data,Baseline,The average long-term defect level of a process when all input variables in the process are running in an unconstrained fashion.,Entitlement,The best-case short-term defect level of a process when all input variables in the process are centered and in-control.,Benchmark,The defect level of the process deemed by comparison to be the best process possible.,eg:best WinBench numbers,against Maxtor,Fujitsu drives,22,Breakthrough Improvement,Tim
