My company as you know is presently ISO 9001:2008. I was in the process of transitioning to ISO 9001 2015. My company decided to change over to TS 16949-2016 instead. At this time I am having to start over. My question to you is, can I use any of the templates that I purchased from you? Or would I have to purchase new templates for TS?
IATF 16949 is practically ISO 9001:2015 plus requirements for automotive industry. If you take a look at the text of IATF 16949, you can see that it refers to requirements of ISO 9001 but due to copyrights it doesn't quote the ISO 9001.
Also, some of requirements of IATF 16949 are completely the same as in ISO 9001 and in these cases you can use the documentation of ISO 9001 Documentation Toolkit as is (for example context of the organization), in other cases you only need to amend the documentation to meet additional requirements of IAT F 16949.
