An increasing number of business organizations are supporting business-driven Enterprise Architecture (EA) efforts but most of these projects mix multiple EA frameworks leading to in-house developments. It seems that, based on Gartner survey, the upcoming EA frameworks will take advantage of the already existing different sets of reference frameworks and methodologies to develop pragmatic and g...

Today’s enterprise environment is more sophisticated than ever and being able to manage this complexity is not possible without having a planned approach. Enterprise architecture (EA) has emerge as a planned approach to mitigate the organizational complexities and control the constant environmental changes.

The enterprise architecture (EA) is defined as a coherent and consistent set of principles and rules that guide system design. In the EA modelling methods, an enterprise is identified with institution, business or administrative unit. The EA development methods mostly focus on the EA internal problem visualization, as well as on the procedural and different viewpoint approaches. However, in thi...

Inspired by the city planning metaphor, enterprise architecture (EA) has gained considerable attention from academia and industry for systematically an IT landscape.

In earlier work we introduced an approach that aims in the understanding of the reasoning that lies behind Enterprise Architecture (EA) designs. This EA rationalization approach helps uncover design constraints, follow good practices while avoid bad ones, and more. However, up to now, our assumptions regarding the usefulness of our approach were largely theory based. In this paper, we use a rea...
