7: Maintenance
Maintain the Enterprise Architecture Other Information:
The EA is, by definition, a set of models that collectively describe the enterprise and its future. Its value to the business
operations is more than just IT investment decision management. The EA is the primary tool to reduce the response time for
impact assessment, tradeoff analysis, strategic plan redirection, and tactical reaction. Consequently, the EA must remain
current and reflect the reality of the organization's enterprise. In turn, the EA needs regular upkeep and maintenance --
a process as important as its original development. Maintaining the EA should be accomplished within the enforcement structure
and configuration control mechanisms of the organization. EA maintenance is the responsibility of the CIO, Chief Architect,
and the EAPMO. Using a system of oversight processes and independent verification, the architecture core team periodically
assesses and aligns the EA to the ever-changing business practices, funding profiles, and technology insertion. The EA should
remain aligned to the organization's modernization projects and vice versa. The management controls to accomplish EA maintenance
are the same ones established to initiate the program and to develop the EA.
