ISO 9000 is a normative standard called for in 9001. As for the definition of quality and thousands of other terms, ISO offers www.iso.org/obp where anyone can find the definitions of terms used in all of their standards for free.Then she asks us what "qualify" means, and tells us to get ISO 9001:2015 Quality Management Systems - Fundamentals & vocabulary book to find the definition of "qualify" which we paid $250 only to find that definition of "qualify" wasn't even listed on the book, so she was telling us a flat out lie.
