Thanks for those inputs. Just correct me if I've missed anything.. ISO 19011 is used as a reference document for auditing any management system standards.
This new revision ISO 19011:2017 is expected to be released mid 2018. Is this right?
ISO 19011 was originally developed and maintained by the TC 176 as, in it's inception, provided guidance on auditing of quality management systems. With the relative "success" of ISO 14001, the 19011 document was expanded to include also guidance of auditing of environmental management systems.
As the number of ISO Management System Standards grew drastically in the last decade, ISO 19011 is now being revised to provide generic guidance on auditing of management system standards, without limitation on specific disciplines.
To be honest, I did not watch the video clip I provided in my last post, so I am not sure when the next revision is expected to be released, but it could be 2018.
Good luck.
