Foundations of EA

Author: Saurabh Mittal, PhD

Enterprise Architecture has its roots in the 1960s. It came about to analyze areas of common activity within or between other resources that are exchanged to guide the future state of the organization or the enterprise, from an integrated viewpoint of strategy, business and technology.
