Developing Complex Systems With Object-Process Methodology Using Opcat

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.
