ses “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。 understandable by the person who is trying to reduce defects Sigma,a figure of merit • TDUcould be expected to be proportional to the plexity of the unit • Complexity is directly proporttional to the number of opportunities to creat a defect • To normalize processes of different plexity, we use: Total defects Opportunities … From which we can calculate sigma DPMO = x 1,000,000 Improvement 7 Sigma(+ sigma shift) 1 10 100 1K 10K 100K 2 3 4 5 6 (66810 ppm) (6210 ppm) (233 ppm) ( ppm) 30x Improvement 10x Improvement 70x Improvement 6 5 3 4 Defects per Million opportunities Benchmarking 1 10 100 1K 10K 100K 2 3 4 5 6 7 Best in class internal + external Repair costs 10% Average pany 1% Defects per Million opportunities Sigma(+ sigma shift) 1 10 100 1K 10K 100K 2 3 4 5 6 7 Restauant bills Doctor prescription writing Payroll processing Order writeup Journal vouchers Wire transfer Airline baggage handing Purchased material lot reject rate Benchmarking Best in class Average pany Sigma(+ sigma shift) Defects per Million opportunities Process quality levels may vary widely within a pany ( PPM) • 1 10 100 1K 10K 100K 2 3 4 5 6 7 Airline baggage handling Domestic airline flight fatality raate Best in class Average pany Sigma(+ sigma shift) Defects per Million opportunities Implementation of the six sigma culture Total sustomer satisfaction Six steps to six sigma amp。 design for manufacturability Cycle time reduction Motorola’s black belt Problemsolving tools n 驅動力來自評量指標以及合理 且具挑戰性的目標 The sixsteps design process Manufactued product • Identify physical and functional requirements of customer • Determine characteristics of product critical to each • Determine for each characteristic,whether controlled by part,process,or both • Determine maximum range of each characteristics • If CP2 redesign material,profuct,and process as required. Administrative/office • Identify the work you do(your product) • Identify who your work is for(your customer) • Identify what you need to do your work,and from whom(your supplier) • Map the process. • Mistakeproof the process and eliminate delays. • Estableish quality and cycle time measurement and improvement goals. Cycle time reduction Will be coverd in detail afer lunch Problem solving identification tool • All member of the anization should have trining in problem solving indentification tools – Flow charts – Brain storming – Pareto charts – Cause amp。 effect diagram Black belt tools • Process characterization • Process improvements • Graphical data analysis • Distribution analysis(graphical。
