5. Contemporary Approaches to Enterprise Modeling

Chapter 4 provided a broad overview of a number of areas of research and practice that actively employ enterprise modeling. However, the discussion was too coarse to be of much help in understanding state-of-the-art in enterprise modeling, and was intended more as a background for making sense of the concrete approaches presented in the current chapter.

Chapter 5 presents in more detail nine enterprise modeling approaches that all claim to support modeling for the purpose of improving people's understanding of the Universe of Discourse. In order for an approach to be taken into consideration, an extensive treatment of enterprise modeling is required. In addition, a few general-purpose modeling approaches are also considered, as they possess particularly desirable features. A brief comparison and evaluation of the approaches is also provided.

The main outcome of the chapter is an overview of how existing frameworks suggest that enterprise modeling is to be conducted and how they fit the perspective on enterprise modeling outlined in section 3.4.1.
