Analyst(s): Mike Rollings


Although some organizations still struggle with Enterprise Architecture (EA) fundamentals, others have reached a point of diminishing returns as they apply more time and effort to improving EA value. At this crossroads, it is essential to improve the organization's understanding of process, information, and the application portfolio to assure that EA is focused on business outcomes. In this Perspective document, Research Director Michael Rollings discusses the anatomy of an effective EA program and provides recommendations to improve the value from EA.
