Hi Mark
What other people do is a big "it depends"...  (cheque is in the mail Doug)

I've only seen one site where they used a PnP that would do part 
verification, they used it to check the first couple of parts placed per 
job.  More commonly what I have seen and what we do here is a second 
person verification of the parts loaded on the machine against the setup 
for the machine.  It assumes that the right part is on the reel, which 
is usually (99.999%) true.  We have had occasion where we have received 
incorrect parts on the reel, but that is very rare.

We are very high mix here, there is no way we can leave the line 
permanently set up - we typically do 1 - 2 setups per day.  You have to 
be running serious volume to be able to leave the parts setup all the 
time.  The best I've managed was at a previous employer, we were running 
a family of parts that had a fair bit of commonality and I was able to 
leave the common parts on the machine most of the time.  Usually though 
that takes too many feeder slots, and too many feeders - one never has 
enough feeders...
