Doug,
We have some experience in this area with a number of clients who distribute
auto parts, as well as our own consulting and training company which
distributes (third party produced) educational materials.
Our only verification of product in these situations is based on:
1. Verification of part number as labeled to the part number ordered (for
incoming receipt) or per customer shipper (for final inspection of orders.)
2. Visual inspection of the package for handling damage; if found, we
would either open the package to visually inspect the part, or file
a damage claim with the shipper.
This has been fully acceptable to many ISO auditors.
Meanwhile, I can't think of a reference that's specific to distributors, but
I would recommend the book ISO 9000 Implementation for Small Business
by James Lamprecht. This book does a nice job of showing how to
interpret the standard in different small business environments, including
service businesses. His primary case study is a dry cleaning business.
Alas, the edition I have is based on I9000:1994. Don't know if it's been
updated. ASQ publishes it.
Regards,
Brad
