WHAT IS ENTERPRISE ARCHITECTURE?
• Enterprise architecture (EA) is a conceptual blueprint that defines the structure and
operation of an organization. It is a comprehensive framework used to manage and align an
organization's Information Technology (IT) assets, people, operations, and projects with its
overall business goals. The main purpose of enterprise architecture is to create a holistic view
of an entire enterprise from the abstraction of its complex structures and processes.
• EA involves the analysis, design, planning, and implementation of analysis based on an
integrated and cohesive approach to the strategic direction of the business. It helps
organizations to rationalize their IT investments and to reduce redundancy, improve efficiency,
maintain compliance with standards and regulations, and respond more quickly to changing
business environments.

   WHAT IS ENTERPRISE ARCHITECTURE?
   • Enterprise architects, the professionals who perform EA, typically use various frameworks to
   guide the process. Some of the most common EA frameworks include The Open Group
   Architecture Framework (TOGAF), the Zachman Framework for Enterprise Architectures,
   and the Federal Enterprise Architecture (FEA) for use in the U.S. federal government.
   • Effective enterprise architecture provides a long-term view of an organization's processes,
   systems, and technologies so that individual projects can build capabilities—not just for the
   present, but also for the future. This means that changes in business strategy can be reflected
   and supported by the underlying business processes and IT systems.
