The impact of enterprise architecture´s absence in e-Government development: The Greek case

Enterprise Architecture (EA) is a dynamically evolved area, suggesting frameworks and methods to handle complexity and change in an enterprise or in a public agency. Major international e-Strategies follow EA frameworks, which oblige distributed authorities to design and implement their e-Government projects under specific standards and directions. In Europe, European States implement their e-Strategies usually according to European political objectives, directives and frameworks, but not under a common EA. Some European countries have developed their own EAs, while others limited their efforts in aligning their strategies to the European one. In this paper we present the EAs followed by major e-Strategies, together with their recent outcomes. On the contrary, we present e-Government implementation in Greece, where no EA was followed. We use some tenders´ data in order to present the impact of EA´s absence in project design, implementation and sustainability.
