Hi guys! I'd like to know from other auditors' point of view, how can you say that you've covered / sampled out every process? This is the case, we have about 500 operators working on a 3 shift schedule. How many operators should I audit for compliance on the process? My Boss says to use the MIL-STD-105-E as a basis for the number of operators to be sampled out for a particular shift. Under the MIL-STD-105-E, he particualrly mentioned to use the special inspection sample sizes (S3). Is this valid? Thanks and more power.

I know there is at least one thread here where sampling in auditing is discussed. Basically, you are not going to be able to use something as 'scientific' as a sampling table because, amongst other things, you will not always easily know the population size (how many design records do we have?).

If I can find that thread later I'll link it up. In the meantime (unless someone else knows the thread off hand) maybe some others will comment on sample size during audits.

Thread I found:

and

thanks guys for the help!
