【文章內(nèi)容簡介】 tial: For training onlyElement of Fishbone diagramn Usually, there are six elements (6M) for a fishbone diagram:n Machinesn Measurementsn Menn Materialsn Methodsn Environments (or Milieu)n Fishbone diagram is developed by team, rather than individually, as it is brain storming process.n Fishbone diagram can be drawn by Minitab.13Belton Confidential: For training onlyExample of Fishbone diagramPotential KPIVs are categorized in the branches of ‘cause’14Belton Confidential: For training onlyCause Effect Matrixn Cause Effect Matrix (CE Matrix or XY matrix) is used to further narrow down the KPIVs from fishbone diagram.n CE Matrix provides more rational results than fishbone diagram.n CE Matrix is developed by team, not individual.n The score is prioritized and then further analyze by FMEA.15Belton Confidential: For training onlyCE Matrix – Process steps1. List down process outputs (KPOVs or Ys)The outputs can be your important to your customer and/or next process steps16Belton Confidential: For training onlyCE Matrix – Process steps2. Rank outputs with respect to customer importance17Belton Confidential: For training onlyCE Matrix – Process steps3. List down key inputs (KPIVs or Xs)18Belton Confidential: For training onlyCE Matrix – Process stepsn You are ready to correlate customer requirements to the process input variablesn Allow sufficient time for assignment of scoringn Avoid confusion and inconsistency by establishing scoring criteria:0 = no correlation1 = the process effect only remotely affects the customer requirement4 = The input variable has a moderate effect on the customer requirement9 = The input variable has a direct and strong effect on the customer requirments19Belton Confidential: For training onlyCE Matrix – Process steps4. Correlate X’s to Y’s20Belton Confidential: For training onlyCE Matrix – Process steps5. Rank the priority by it calculated score6. You can also use Pareto Chart to have visualization on KPIVs.21Belton Confidential: For training onlyFMEAFMEA: Failure Modes and Effects AnalysisFMEA is a systematic approach used to examine potential failures and prevent their occurrence. It enhances an engineer’s ability to predict problems and provides a system of ranking, or
