For EA to support an enterprise holistically, it must link strategy, business and technology. EA is most effective when it simultaneously supports top-down executive planning and decision-making across the enterprise and bottom-up management planning and decision-making within each LOB. In this way, EA helps to ensure that strategy drives business and technology planning. From a business perspective EA provides the context and purpose of business activities by ensuring technology is implemented only after business requirements are identified. From a technology perspective, EA provides the strategy and business context for resource planning. This can be critical when working with multiple organizations to create common resources (i.e., supply chains) or in merging / acquiring organizations into one enterprise.
