For over a decade, IT-business alignment has been ranked as a top-priority management concern, but there is little research on practical ways to achieve the alignment. EA development is a continuous iterative process, which implicitly ensures the achievement of a specific IT-business alignment level. Therefore, it is necessary to formalize the requirements for architecture and be able to automatically verify them. The authors propose a new methodology for detecting logical contradictions in enterprise architecture models based on a model checking approach adopted in the context of business modeling. In such a methodology, they use ArchiMate standard for a conceptual enterprise architecture description language which is fully aligned with TOGAF. The authors also offer several important verification queries and demonstrate practical applicability of their approach using a software prototype of the modeling tool which exploits MIT Alloy Analyzer model checking framework integrated with AchiMate Archi workbench.
