I am QM at a facility that is ISO 9001:2015 certified. Our customers are mandating ISO IATF. Here is my question...my management wants me to go from ISO 9001:2015...to ISO TS16949:2016....to ISO IATF. Does that sound like best approach? I noticed that ISO 9001:2015 is "set up" like ISO IATF. Is the planned route the best? Thank you.
