I have with and for companies that got the SO 9000/9001 accreditation, and then went back to what they were doing before. They just wanted the accreditation for the bragging rights.
... and those bagging rights can be quite valuable when bidding on contracts. ISO 9000 accreditation is very impressive to most source selection teams. The challenge can be when the contract is executed -- when the rubber meets the road. If the company is really committed to the quality process then all goes well; if not or if those processes aren't fully integrated in all divisions, then it might not go well.
