A Rough Primer on Enterprise Architecture - I produced this page after fielding a question for a succinct definition, in three pages or less, describing what Enterprise Architecture is, and how it is valuable.  Unfortunately, I don’t have time at the moment to pull all the various strands of information together as a nifty three page document.  What I can do, at this time, is provide a series of links to prior articles that can help to describe and define Enterprise Architecture from my point of view.  First off, let me say that Microsoft does not favor, endorse, or promote any particular EA framework.  We have had experience with numerous approaches and frameworks, have developed our own metamodel and framework for internal use that guides our strategic planning.  Our consulting organization, Microsoft Consulting Services has many Enterprise Architects among the ranks.
