4.1 Introduction to the Survey

Before introducing the areas, a few considerations are required both with respect to the limitations of the assessments and the criteria for inclusion in the survey. An outline of the presentation is also provided.

4.1.1 Limitations of the assessments

Describing and discussing comprehensive fields like software engineering in just one page of text necessarily have to be superficial and involve massive simplifications. Hence, the presentation must be based on what is perceived to be typical.

Moreover, surveying several areas of research and practice in detail requires extensive resources (at least more than have been available in this research project). Hence, the investigations are based on literature that are perceived to be mainstream. "Exhaustive" reviews have not been attempted.

A timely question concerns the value of conducting the survey at all when the limitations are as severe as indicated above. The answer to this is that the main intention is to convince the reader that although enterprise modeling is an issue in many communities of research, the challenges and opportunities in those areas may differ substantially. Comparison of two approaches to enterprise modeling without taking notice of their background may result in evaluation on wrong grounds. Hence, the survey is an attempt at making the strategies chosen by enterprise modeling approaches presented later more sensible.

4.1.2 Criteria for being included in the survey

A central criterion for including areas in the survey is the explicit use of the term enterprise modeling. In addition, the survey includes a few areas that fit the purpose stated in the main research question, or the practice exposed in the three initial empirical studies. The following areas are included: The work reported in this chapter is founded on a similar survey reported in (Totland and Conradi, 1995), but then with the perspective of discussing areas related to software process modeling.

4.1.3 Presentation of the areas

To discuss the areas, the taxonomies developed in sections 3.5 and 3.6 are applied: To summarize the assessment of the role of enterprise modeling within an area, the symbol of is employed. Each rectangle is marked according to the assessments (i.e., a rather coarse binary system).

If an area is assessed as advocating enterprise modeling for computer-assisted analysis and the type of work that is modeled is dominated by replication risk and matter, the assessment rectangle would be marked as follows:  

In addition, the relevance of the area to enterprise modeling and any particularities are discussed.
