===ISO and OPM===

In June 2008, Richard Martin approached [[Dov Dori]] after his presentation at the [[International Council on Systems Engineering|INCOSE]] International Symposium in Utrecht, the Netherlands, to inquire about the possibility of creating an International Standard for OPM.{{Citation<ref needed|datename=May":0" 2017}}/>. Martin, convener of ISO TC184/SC5/WG1 for automation systems interoperability architecture and modelling, had for some time been searching for methodologies offering more than static information and process modeling.{{Citation needed|date=May 2017}} He provided Dori with a simple example to model that could demonstrate both the modelling capability of OPM and its dynamic simulation opportunity.{{Citation needed|date=May 2017}}

In May 2010, Dori presented a brief overview of OPM and his demonstration model at the ISO Technical Committee 184/Sub-Committee 5 (TC184/SC5) plenary meeting, which then adopted a resolution to create an OPM Study Group for the purpose of examining the potential for OPM to enhance the standards created by SC5.<ref>{{cite web |last1=Dori |first1=Dov |last2=Howes |first2=David |last3=Blekhman |first3=Alex |last4=Martin |first4=Richard |title=OPM as a Basis for Model - Based Enterprise Standards, Report of the ISO TC184/SC5 OPM Working Group to the Plenary ISO TC184/SC5Meeting, Tokyo 26, 2010 |url=http://esml.iem.technion.ac.il/wp-content/uploads/2011/05/OPM_WG_Report_to_TC184-SC5_Tokyo_March_26_2010.pdf |access-date=18 November 2018}}</ref>

The OPM Study Group began its work in October 2010 and issued an interim report for the 2011 SC5 Plenary.<ref name=":0">{{cite web |last1=Blekhman |first1=Alex |last2=Dori |first2=Dov |last3=Martin |first3=Richard |title=Model-Based Standards Authoring |url=http://esml.iem.technion.ac.il/wp-content/uploads/2011/07/Model-Based-Standards-Authoring-March-2011.pdf |access-date=18 November 2018}}</ref> The report included several uses of OPM to model existing SC5 standards and led to an initial motivation for the standardization of OPM with the realization that being text-based, ISO standards are prone to suffer from inconsistencies and incomplete information. This deficiency could be significantly reduced if the standards were model-based rather than text-based, and OPM offered a useful underlying modeling paradigm for this purpose.

A final OPM Study Group Report and a draft for a metamodel for model-based standards authoring document were delivered at the 2012 SC5 Plenary.<ref>{{cite web |last1=SC 5 PLENARY MEETING |title=Meeting Report |url=http://esml.iem.technion.ac.il/wp-content/uploads/2011/05/ISO-TC184-SC5_N1185_2012_SC5_Plenary_Meeting_Report_-_Haifa_.pdf |access-date=18 November 2018}}</ref> As the OPM Study Group effort progressed, it became obvious that OPM could also serve as a solid and comprehensive basis for model-based systems engineering (MBSE) and for modeling both natural and man-made systems.{{Citation needed|date=May 2017}}
