Graphical modeling techniques and usefulness in the Model Driven Arcitechture: which are the criteria for a "good" Computer independent model?

The Object Management Group (OMG) has presented a framework for model driven development: Model Driven Architecture (MDA). The departure point of this paper is an interest in process oriented modeling techniques relevant for a computer independent model in the MDA. We searched for the answer on the question what constitutes a "good" computer independent model (CIM). To get an answer we were using OMG:s demands of the modeling techniques that should be used when developing CIMs and found four process oriented modeling techniques which could serve as candidates. These four process oriented modeling techniques is analyzed based by Moody"s quality criterions. The findings indicates that there are only one candidate, BPMN, that meets some of Moody"s quality criterions, but there also drawbacks in BPMN, such as the criterions; expressiveness and emphasis.
