The latest information from the Big 3 is that you will have a choice between QS9K and ISO16949. You (ie, your organization) will have to determine which standard makes the best business sense for you to follow. I think there are still some questions about the registration scheme and about the Customer-specific requirements at the moment (for ISO16949), but that should clear up soon. ISO16949 is based on ISO9000:1994 (for now) and is meant to be an automotive "appendix" to ISO9000. So when ISO9000:1994 changes to ISO9000:2000, so will ISO16949 change to conform with ISO9000:2000 version. By the way, you can get a copy of ISO16949 from ASQ or AIAG. (The last that I heard, though, is that still comes without any customer-specific requirements.)
