Correct me if I am wrong, but typically the procedure has been written by the department who performs the day to day functions. We then take the procedure and make a checklist based on the written procedure, and take questions from the procedure. Is this not auditing the process? Hope this makes sense.
Basically, Ron. As Dave says there's a lot more to it than that, if you are to determine if the process is effective. For example, if we take Purchasing, I always audited to see how many purchase reqs sat on the buyers desk because they weren't filled out with the correct minimum information, causing delays in placing the PO etc while the buyer had to 'sort them out' (not their job, obviously).
If the process was effective, the buyer should be able to pick up the req and place an order (well, pretty much). Instead, the percentage of 'right first time buys' is often low, although they do 'follow the process', they also cause problems. This is often because the people who write the purchase reqs don't know how much info is needed, because the procedure etc doesn't tell them (the standard says 'criteria' - under 4.1 c)
