So, other existing models for process analysis containing convenient solutions and indicators...
While several role-related concepts play an important role in business modeling, their definitions, relations, and use differ greatly between languages, papers, and reports. Due to this, the knowledge captured by models is not transferred correctly, and models are incomparable. In this paper, we provide a meta-model and definitions for several role-related concepts based on the practice of existing...

This paper suggests a method for constructing an enterprise architecture...
