2、n steps for correcting out-of-control points? Does the supplier show the evidence of aggressive corrective actions on out-of-control points?33Identify Critical Parameters. Has the supplier identified Process and/or Product Critical Parameters? Can the supplier show that those identified critical par

3、ameters affect the customer experience?24Review specifications for the critical characteristics. Does the supplier have the process to define specs based on engineering and tolerance analyses? Does the supplier have the process to tighten up specs or do they maintain the same spec always? Has the su

Reproducibility ) result acceptable?36Implement X-bar and R variable data control charts on the critical parameters. Has the supplier evaluated the Beta error based on the subgroup siz

5、e? Does the supplier have the documented process on X-bar and R charts, business owner, and action steps for correcting out-of-control points? Does the supplier show the evidence of aggressive corrective actions on out-of-control points? Has the supplier shown the evidence of process stability (base

6、d on 25 consecutive points within the control limits)?37Calculate CP and CPK. Has the normality of the data been tested? The data should be Stable and Normal. 38If Cp is not same as CPK, plan the actions to make CP=CPK. If CPK is below 1.33, plan the actions to raise CPK to 1.33. Show the action pla
