While abstract, IT enterprise architecture has shaped, is shaping, and will continue to shape information technology. For the emerging Service-Oriented Architecture (SOA), Enterprise architecture is one of at least two types of IT architectures, the other being a supply chain supporting architecture (which is known as Internet architecture, SOA 2.0, etc.). Enterprise architecture is directly controlled by a single organization, while supply chain architecture enables and supports multiple independent organizations allied for a common goal, like the production of a new aircraft, a movie, or support of the business traveler. This paper is in four parts and focuses on constructing agile enterprise architecture to align IT with organizational process goals and strategies, helping to ensure the organization’s success in a constantly changing economic and political environment.
