Raymond - typically, a process audit is considered a "horizontal" audit - since the process flow is across the facility. Maybe it's your terminology which is throwing us off? Anything we could give you would be so generic as to be useless, so (as with most audits) your own preparation is going to be important. If you are simply looking for one to see what it's like, check out the post attachments list (hot linked above in green). You might find something there.
