Enterprise Architecture (EA) provides the analysis and documentation of an enterprise in its current and future states from a strategy, business, and technology perspective. EA is a management instrument/program that is part of the overall governance process.
EA helps a company to innovate and change. Insights provided by EA are needed on the one hand to determine the needs and priorities for change from a business perspective, and on the other hand in assessing how the company may benefit from technological and business innovations.
