UML-compatible processes

Current object-oriented methodologies are process focused. Two prominent examples are RUP (Rational Unified Process) and OPEN (Object-oriented Process, Environment and Notation). Both are compatible with the use of UML. Following a brief overview of both processes and a summary comparison, we than go on primarily to evaluate the RUP terminology and constructs against OPEN as a reference model in the sense that OPEN provides a metamodel and terminology well aligned with the ANSI standard defined by the Project Management Body of Knowledge (PMBOK).
