Enterprise Architecture Tool Selection Guide


An enterprise architecture (EA) establishes the organization-wide roadmap to achieve an organization‘s mission through optimal performance of its core business processes within an efficient information technology (IT) environment. Simply stated, enterprise architectures are ―blueprints‖ for systematically and completely defining an organization‘s current (baseline) or desired (target) environment. Enterprise architectures are essential for evolving information systems and developing new systems that optimize their mission value. This is accomplished in logical or business terms (e.g., mission, business functions, information flows, and systems environments) and technical terms (e.g., software, hardware, communications), and includes a transition plan for transitioning from the baseline environment to the target environment. If defined, maintained, and implemented effectively, these blueprints assist in optimizing the interdependencies and interrelationships among the business operations of the enterprise and the underlying IT that support these operations. It has shown that without a complete and enforced EA (Strategic) Business Units of the enterprise run the risk of buying and building systems that are duplicative, incompatible, and unnecessarily costly to maintain and interface. For EAs to be useful and provide business value, their development, maintenance, and implementation should be managed effectively and supported by tools. This step-bystep process guide is intended to assist in defining, maintaining, and implementing EAs by providing a disciplined and rigorous approach to EA life cycle management. It describes major EA program management areas, beginning with: 1. suggested organizational structure and management controls 2. a process for development of a baseline and target architecture, 3. development of a transition plan. The guide is especially focusing on EA tool selection requirements, as well as showing an oversight over existing products today on the market
