Yes, i would like to agree with what you are saying.
Actually, i'd much prefer to calibrate an instrument based on stability study. And since calibraton involves some adjustments to the instrument, i thought r&r is in order.
I have come across customers who insist on submitting r&r results with each consignment.
I am not sure if 'Audit Cycles' would be acceptable to them.
So, the original question remains:
- At what frequency should the MSA be repeated?
Are there any definitive guidelines? At least any thumb rules?
