  • insight 7 Essential Elements of EA Follow this roadmap to engage your business, manage complexity, and govern the implementation of your architecture by David C. Baker and Michael Janiszewski Enterprise Architecture (EA) can be either a cohesive force that binds technology and business operations in support of strategic goals or a misunderstood initiative that undermines the credibility of the entire IT organization. The difference comes in successfully applying the seven essential elements of enterprise architecture—proven principles that should be a part of any EA undertaking.

However, business stakeholders to develop a set of unlike civil architecture, EA does not have guiding principles, our first element. a rigorous blueprinting methodology.
