An Enterprise Architecture Alignment Measure for Telecom Service Development

The increasing complexity of modern Information Services (IS) makes necessary to carry on review activities. For many companies, these reviews take place within the framework of the Enterprise Architecture, which aims at sharing components among applications within the IS. These reviews can for instance help the architects in detecting alignment problems between an analysis model and a design model constrained by the enterprise data model. We propose an automatic approach, relying on Model Driven Engineering (MDE), to measure such an alignment. We propose a set of measures which are formally defined using a classical axiomatization approach. We describe how these measures can be implemented with MDE techniques. We finally illustrate their use for the France-Telecom IS of telecom services.
