I have ten iso9001:2008 internal auditors in my company. Is it feasible for me to train them with the iso9001:2015 standard instead of taking traing courses from service provider ? My boss think that there is no change in iso19011, so he asks me to train them about the difference and highlights of new version. I am wondering my competency on training them and their recognition as i am just irca iso9001:2015 lead auditors. Thanks.
