Overview of ISO 19450

Abstract

This book contains a comprehensive coverage of OPM that is compatible with ISO 19450 Publically Available Specification (PAS) titled ``Automation systems and integration---Object-Process Methodology'', and in French: ``Systèmes d'automatisation et intégration---Méthodologie du processus-objet''. The ISO 19450 PAS has been adopted by the International Organization for Standardization (ISO) in December 2015 through the work of ISO Technical Committee 184/ Sub-committee 5 (TC184/SC5) after a six-year effort, mainly by Richard Martin, David Shorter, Alex Blekhman, and this author. This book was prepared in parallel with the ISO 19450 PAS standard, so the two are almost completely aligned with each other. Since the standard (formally PAS) must conform to the rules of ISO for standard authoring, it is structured differently and is not as elaborate as the book. Rather, it is an orderly exposition of OPM that enables tool developers to use it, along with this book, as a solid basis for developing an ISO 19450-complaint software tool to support OPM-based conceptual modeling. ISO standards like ISO 19450 PAS contain normative parts and often also one or more informative parts. To be compliant with the standard, a normative part must be strictly followed, while an informative part is not mandatory. This book is a superset of ISO 19450 PAS. About 90% of the material in this book is aligned with ISO 19450. The rest can be considered as the equivalent of an addition to the informative part of the standard---it should be followed, but ISO 19450 in its current initial form does not mandate it. This closing chapter describes briefly the content of the ISO 19450 PAS, where each section is devoted to a summary of one or more sections of ISO 19450.
