If ISO is taken properly as a base for quality improvement, then, yeah, I would buy from an ISO registered company. But it is also true that a company could produce a high level of scrap and as long as they handled the scrap properly, ISO 9000 would bless their system. Hmmmm, I am glad they are rewriting ISO 9000. It needs to have the customer more in mind. Unfortunately, too many companies still just want that piece of "registration" paper to hang on the wall without including some TQM thinking.
