- 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.

- A well known trade-off effect with modelling is that when it is user friendly it becomes ambiguous and when it has a formal notation, that makes it unambiguous, it becomes less user friendly. A well known solution to this dilemma is to use models on various levels of formalism where the least formalized models are known to be more user friendly and the most formalized models are well suited for being directly translated to program code. This article investigates how the user friendliness at an informal level can be combined with the accuracy needed at a more formal level of modeling. It aims at combining an informal user friendly perspective with a formal developer perspective in order to minimize the time spent on transformation mapping between user friendly models and developer models. Theoretical data and empirical data indicates possibilities of minimizing the work with transformations between models. The results show that a number of developed criteria can be used to secure the user friendliness of models that are used in communications between the designer and the end user.
