Abstract: Enterprise Architecture is an instrument that focuses on coherence between business processes, information distribution and technology infrastructure of an organization. In practice, the interrelationship between architectural aspects is not always dealt with in an integrated fashion. Enterprise Architecture frameworks are mostly informal by nature and there is a lack of knowledge and tools to support architects to check alignment in a formal manner. Due to volume and complexity of holistic enterprise spanning architecture, it is increasingly challenging for organizations to maintain overview and coherence of architectural elements. This research enables automated rule-based monitoring consistency and coherence between elements within an EA. It does so by creating an artifact that provides architects with the capability of monitoring validity within ArchiMate EA models. The models are validated against formalized rules that are specified in Relation Algebra with which coherence can be mathematically proven. The set of applied rules is plotted onto a quality framework that calculates overall alignment of an EA model. Overall alignment calculation of the researched cases show an overall alignment score varying from 47,53% to 77,27%. Every single rule violation that influences the score is identified specifically. Monitoring EA quality using formalized rules enables organizations to manage and control the process of EA change and thus contributes to Business/IT-alignment.
