What is the purpose of having ISO 9001 and ISO 9004 as a “consistent pair” of standards?
The idea of a “consistent pair” of standards is central to ISO 9001:2000 and ISO 9004:2000. The aligned structures of ISO 9001 and ISO 9004 have been designed to encourage organizations to look at their activities from a process standpoint, and also to look beyond the achievement of registration/certification to ISO 9001, to the implementation of a quality management system that will be truly beneficial in improving operational performance.
