Developing Complex Systems with Object-Process Methodology Using OPCAT Dov Dori, Iris Reinhartz-Berger, and Arnon Sturm   View Paper (PDF)   Return to Industrial Session II Abstract OPCAT – Object-Process CASE Tool – is an integrated systems engineering environment. It supports system lifecycle evolution using Object-Process Methodology (OPM). OPM integrates the object-oriented (structure) and process-oriented (behavior) paradigms into a single frame of reference through a combination of graphics and equivalent natural language. This short paper briefly describes OPM and demonstrates highlights of OPCAT and some of its capabilities. ©2005 Association for Computing Machinery
