Enterprise Architecture (EA) provides a road map that identifies the relationships among the processes, data and IT infrastructure found in an organization's IT environment, which typically includes diverse platforms from a variety of suppliers. EA looks beyond engineering to examine issues like business and technical needs, application delivery concerns and requirements for the analysis and distribution of business and technology information.

This paper explores the evolution of Enterprise Architecture and its support for successful Enterprise Planning. It also examines how Telelogic® System Architect® addresses the current and future requirements of EA activities.
