Standards
IS 14258: Industrial Automation Systems - Concepts and Rules for Enterprise Models, ISO TC 184/SC5/WG1, 1998
The standard defines 'the elements to use when producing an enterprise model, concepts for life-cycle phases and how these models describe hierarchy, structure and behaviour', together with guidelines and constraints for relating the real-world to enterprise models through views - this latter concept is equivalent to the views of ENV 40003.
Intended audience: primarily enterprise model designers and standards-makers.
