    Thank you for your replies !

    @cseider I’m trying to do this because when I do a test on a component, sometimes it can last 5 min, some other times 2 hours. So if I do a full Gage R&R study, with 3 operators, 10 parts and 3 tries, it will take too much time.
    Yeah I’m aware for the impact on the variation, but I wanted to be sure if this impact isn’t significant.

    @rbutler yeah the less you have repeated measures the less precision you have on the value of the standard deviation of the GRR, but is there a certain number of try from which the difference between a GRR found with 10 tries and a GRR found with less tries is insignificant ?

    Hello,

    I’m the poster.
    Thank you for your response !
    Indeed, in my case the impact of the difference between operators isn’t felt. So I will substitute the operators by the the gages.
