Analytic Pattern and Tool for Analysis of a Gap of Changes in Enterprise Architectures

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 language independent analytic pattern suitable for using in tools. The paper describes a tool built on the basis of this definition. The change analysis without the tool and with the tool output has been tested in a workshop. The added value of the tool was acknowledged by the workshop participants.
