We're so small, EVERYONE of the office personnel (including the owner/president) is expected to be an internal auditor.
That's only 6 people.
We've had production personnel in the program before, and we will again shortly. The first time they "joined" they volunteered. We're not sure YET how they will be "picked" this summer. We're currently very light on people...
But since we're more focused on OUR needs and less on the ISO elements, its not as HARD as when we were auditing to 1994 with our last Quality manager.
(Will be upgraded to iso9k2k shortly).
