Belton Confidential: For training only 15 Cause amp。 Effect Matrix ? Cause amp。 Effect Matrix (Camp。E Matrix or XY matrix) is used to further narrow down the KPIVs from fishbone diagram. ? Camp。E Matrix provides more rational results than fishbone diagram. ? Camp。E Matrix is developed by team, not individual. ? The score is prioritized and then further analyze by FMEA. Belton Confidential: For training only 16 Camp。E Matrix – Process steps 1. List down process outputs (KPOVs or Ys) The outputs can be your important to your customer and/or next process steps Belton Confidential: For training only 17 Camp。E Matrix – Process steps 2. Rank outputs with respect to customer importance Belton Confidential: For training only 18 Camp。E Matrix – Process steps 3. List down key inputs (KPIVs or Xs) Belton Confidential: For training only 19 Camp。E Matrix – Process steps ? You are ready to correlate customer requirements to the process input variables ? Allow sufficient time for assignment of scoring ? Avoid confusion and inconsistency by establishing scoring criteria: 0 = no correlation 1 = the process effect only remotely affects the customer requirement 4 = The input variable has a moderate effect on the customer requirement 9 = The input variable has a direct and strong effect on the customer requirments Belton Confidential: For training only 20 Camp。E Matrix – Process steps 4. Correlate X’s to Y’s Belton Confidential: For training only 21 Camp。E Matrix – Process steps 5. Rank the priority by it calculated score 6. You can also use Pareto Chart to have visualization on KPIVs. Belton Confidential: For training only 22 FMEA FMEA: Failure Modes and Effects Analysis FMEA is a systematic approach used to examine potential failure
