As a prerequisite to the development of every enterprise architecture, each Agency should establish the need to develop an EA and formulate a strategy that includes the definition of a vision, objectives, and principles. The figure shows a representation of the EA process. Executive buy-in and support should be established and an architectural team created within the organization. The team defines an approach and process tailored to Agency needs. The architecture team implements the process to build both the baseline and target EAs. The architecture team also generates a sequencing plan for the transition of systems, applications, and associated business practices predicated upon a detailed gap analysis. The architecture is employed in the CPIC and the enterprise engineering and program management processes via prioritized, incremental projects and the insertion of emerging new technologies. Lastly, the architectures are maintained through a continuous modification to reflect the Agency's current baseline and target business practices, organizational goals, visions, technology, and infrastructure.[
