【正文】 duct Scorecard 22 Six Sigma Champion Training Core Product Technology Development Product Idea Concept Proof of Technology Innovation Planning Concept Transition Customer Request Design Evaluation Customization Validation Product Application Current Product Support Production Ongoing Build Support We begin roughing out the Product Scorecard during the “Proof of Concept” phase And continually update at each subsequent phase. How does “Product Scorecard” fit within the overall Product Design Process 23 Six Sigma Champion Training Product Scorecard and the Traditional Cost Bill of Materials $ s ? Cost bill of materials – $/part – $/operation – TOTAL COST $ ? Product Scorecard – DPMO’s (Defects per million opportunities) – TOTAL SIGMA s ? Effective panies achieve products featuring High Sigma39。s and Low Cost. 24 Six Sigma Champion Training Using the Product Scorecard with the Breakthrough Strategy PRODUCT IMPROVEMENT PLAN CURRENT PRODUCTS NEW PRODUCTS NO YES NO YES YES USE SIX SIGMA SCORECARD P.D.P.

A list of key customer Characteristics/requirements from contract from a product FMEA from test requirements ? Product measurements against those characteristics/requirements test data simulation data past product data Filling Out the Performance Worksheet What Information Do You Need? 26 Six Sigma Champion Training ? All customer key requirements should be listed (some translation to engineering terms may be required) ? Other potential performance parameters to add are those tested during qualification or checked during production ? All data used is assumed to be long term, if short term data is all that is available the appropriate conversions must be made Performance Worksheet Ground Rules 27 Six Sigma Champion Training P r o d u c t N a m eP a r t s P r o c e s s s P e r f o r m a n c e s P r o d u c t sA c t i v i t yD P U E s tO p p C o u n tD P U E s tO p p C o u n tD P U E s tO p p C o u n tD P U E s tO p p C o u n tT o t a l s 0 . 0 0 0 0 0 0 0 . 0 0 0 0 0 0 0 . 0 0 0 0 0 0 0 . 0 0 0 0 0 0Fi r s t T i m e S i g m a N U M !

Pareto Chart of part numbers with highest DPU`s ? Which part has the highest DPU impact? ? Which supplier has the highest DPU impact? Is there another supplier? ? Sort total DPU across programs by supplier ? Total part count/total line item count (Are we using DFM principles?) ? Can you design out high DPU parts? ? Use data for make/buy decisions? Parts Analysis 29 Six Sigma Champion Training ? Which process step contributes most to the product DPU level? ? Can the process be improved? ? Is there an alternate process/technology? ? Would capital expenditures help? ? Can the need for the process be designed out? ? Is there a part/process interaction causing the defects to occur? Process Analysis 30 Six Sigma Champion Training ? Test different design options using a Z score approach ? Make business decisions based on cost and predicted defect rate Are we over/under designing ? What type of test/measurement equipment is required to evaluate a given parameter ? Use designed experiments to improve a particular output by understanding Y = F(X) Performance Analysis 31 Six Sigma Champion Training DPMO Defects per million opportunities DPU Defects per Unit TDU Total defects per unit NORMSINV An Excel function returns the Z value associated with a given tail area probability NORMSDIST An Excel function returns the defect probability given a Z value EXP The value e raised to a power。 Yield = eDPU Avg. Sigma The Z or Sigma value obtained by dividing the Total Defects per Unit by the Number of Opportunities First Time Sigma The Z or Sigma value obtained using the Total Defect level as in First Time Yield Some Definitions 32 Six Sigma Champion Training 謝謝觀看 /歡迎下載 BY FAITH I MEAN A VISION OF GOOD ONE CHERISHES AND THE ENTHUSIASM THAT PUSHES ONE TO SEEK ITS FULFILLMENT REGARDLESS OF OBSTACLES.
