Extending Enterprise Architecture Modeling Languages: Application to Requirements of Information Systems Urbanization

Abstract

The Information System (IS) is currently the main part of the business strategic dimension. The urbanization of information systems is necessary for a global vision of the IS architecture over space and duration for any computerization project. It proposes defining a coherent development plan in phase with the strategy, trades, and the processes. Many frameworks, methods and software tools of Enterprise Architecture (EA) are available on the market and have integrated the concepts of urbanization which are inspired by cities' urbanization. In addition, these methods may be provided in a different way from a tool to another. Some of these tools include the urbanization concepts; however other tools are lacking these concepts but allow the possibility of extension. It is in this context that the subject of this paper that allows customizing a modeling tool in order to take into accounts some concepts and specific urbanization's rules. Such customization is based on the previous work on the urbanization of enterprise's information systems and applied on a well defined tool that is Archi which is based on the Archimate framework after a study of the tools available on the market. In addition, this article shows how we can customize Archi tool for the needs of the urbanization of the information system.  urbanization that are mentioned above. Our problem is then to understand how to add this extension with a conceptual and technical standpoint.

Examination of explicit definitions of enterprise architecture

“…“ Indeed, the Anglo-Saxon world has proposed the enterprise architecture as an efficient solution in terms of modeling business, organizations and enterprise processes. ” 54…”

“…"Indeed, the Anglo-Saxon world has proposed the enterprise architecture as an efficient solution in terms of modeling business, organizations and enterprise processes." 54 Why. "An EA is a governance instrument intended to facilitate the translation from corporate strategy to daily operations."…”

An exploration of the many ways to approach the discipline of enterprise architecture

“…185 Yet another indicates 'a lack of theoretical foundation, definition, or common understanding' among researchers who have published in EA. 270 Still others address this issue by questioning the differences between the approaches of enterprise architects. For example, 99 explains how there are an increasing number of enterprise architects, 'but there is no universally accepted baseline of standards and knowledge to ensure consistent service'.…”
