Enterprise architecture modifiability analysis

Abstract

As changes to organisations and the systems supporting them are getting ever more rapid, the modifiability of evaluation architecture is becoming ever more important. This paper presents a proposal of a scenario-based method for evaluating the modifiability of enterprise architectures. The method has been developed as an adaptation of the Software Architecture Analysis Method (SAAM) onto the field of enterprise architecture. It assumes that such architecture should be represented as a set of models in the ArchiMate language. The proposed method delivers an architecture assessment process together with techniques supporting the architecture assessment, such as representing requirements as scenarios of probable changes, analysing the impact of the changes represented by scenarios on enterprise architecture. The method has been validated on a real world example of an Enterprise Architecture of a Social Policy Support Entity of a certain municipality.
