Enterprise Architecture (EA) is more than the collection of the constituent architectures (Business, Application, Technology, and Information). It is a conceptual tool that assists organizations with the understanding of their own structure and the way they work. It provides a map of the enterprise and is a route planner for business and technology change. EA is intended to address important Enterprise-wide concerns, such as:

• Meeting stakeholder and customer needs
• Aligning IT with the business
• Seamless integration and data sharing
• Data integrity and consistency
• Reducing duplication
• Utilizing EA as a tool for strategic, acquisition, and capital investment planning
