Is GRR included for all new or modified gauges, measurement and test equipment?
For gauges shared with other programs, is GRR valid (i.e. less than a year old and done on tolerance band equal or tighter than the tolerance on drawing dimension)?
Is GR&R acceptance criteria followed?: GR&R < 10 is Acceptable, GR&R from 10 to 30 is questionable and requires action plan for improvement, GR&R > 30 will be Rejectable
Is corrective action plan submitted for all rejectable items at the time of submission (action, responsible, due date)?
Are number of Distinct Categories (ndc) index equal or higher than 5 on GR&R studies?
Is Variable GR&R performed preferably with three operators, ten parts, three repetitions?
Is Attribute Studies performed preferably with 20 parts (10 good and 10 bad), with 2 operators and 2 trials?
If there is a dedicated fixture/gauge, is there a layout verified by approved third-party inspection facility?
Are work instructions included for use of dedicated fixture/gauge?
Do measurement devices used have higher resolution than print (e.g., print X.XX and measurement device is X.XXX)?
