ISO 9000?
Once put to me as "It ensures you can produce anything including a total load of crap as long as you can consistantly make the same total load of crap every day".
It doesn't mean your product is any good, just consistant!
"And so speaks the old guard"
so obviously your customer is consistently wide of the mark as they pay you $$$$$$$$$$ bucks for your consistently poor product that complies with their consistently poor performance markers...idiot!
