It is critical that organizations align strategic and business goals with IT to simultaneously create internal and external services that reflect what customers really want and need. In addition, decision makers must clearly understand how to manage and predict the effect of change on the organization - an important ability in a business climate with quickly changing business requirements. Enterprise Architecture, with its roadmap showing relationships among the organization processes, data and IT infrastructures, provides a platform for implementing Service-Oriented Architecture, with the ability to embrace change and incorporate new technologies efficiently.
