Change analysis of enterprise architectures is usually done by observing differences between two enterprise architectures, As-Is and To-Be. If the As-Is and To-Be have a lot of differences, it is problematic to manually create a correct view on changes. This paper proposes a revision of a definition of the Gap of Changes and defines it as a languag...

... Some authors [5] propose to see any model change as a trigger for model evaluation and simulation. Another suggestion is to extract a gap-of-changes view from the as-is and to-be Enterprise architectures [2,4] and present this to decision makers for comparison with respect to the goal of changes. However, there is no support for decision making through comparison in the case where a completely new business process or system structure is proposed. ...
The cognitive basis of any decision making process is a comparison. This paper presents evidence from two distinct cases showing that decision making is facilitated by selecting specific sets of business concepts for comparison. The first case illustrates modelling of a new business process that does not exist yet. In this case, the concept for comparison is found outside the modelled business system. The second case presents an improvement of an existing business process, where the concepts for comparison are found inside the model of the existing system and compared with the concepts used in the model of the modified system. These cases identify two ways of selecting concepts for comparison that help to make the key decision to implement or not implement a proposed system model.
