Another viewpoint to look at EA arena is to understand it as a natural progression from Technical Architecture to Solution Arch and then Enterprise. Its the rising scope of strategic context which differentiate EA from the rest. The deliverables for EA must include business scenarios and solutions should follow general principles based on standards and not on specific set of technologies. In other words EA is about driving all business and associated technology as a set of collective, coherent and interrelated set of activities to generate operational efficiencies and strategic competitiveness.
