I work in procurement quality in aerospace, a fairly long way from QS9000. Many of my suppliers are small jobs shops, 10-25 employees.
However, when working with the quality managers, I haul out the QS manuals on
FMEA and
APQP and touch on some of the concepts.
The manuals present logical and structured approach to providing quality product that, in the long run, is cheaper for the supplier and my company.
By no means do I expect them to do full blown FMEAs, control plans, etc.;I may order 250 separate parts a year from a shop in small lots of 6 - 12 pieces.
But manuals do get the management of these small shops thinking about quality from a systems/process approach. And that can hurt either of us.
