Enterprise Architecture (EA)
Federal agencies are required by the Clinger-Cohen Act to develop an Enterprise Architecture (EA). An EA
is a logical structure for classifying and organizing complex information. Section 5125 of the Clinger-Cohen
Act requires agencies to develop sound and integrated information technology architectures. Furthermore, the
OMB budget process requires agencies to indicate the degree to which their IT initiatives comply with the OMB's
Exhibit 300B budget request forms.
From a more practical perspective, a robust EA will enable agencies to align their IT goals and objectives
with the mission, goals, and objectives of the business. Obtaining business/IT alignment however, requires
more than just capturing what technology an agency currently uses to support their mission and envisioning what
will be needed in the future. Achieving alignment requires the full involvement of business process owners
across the organization in collaboration with IT decision makers, as well as the integration of the EA program into the
normal operations of the organization. An effective EA requires governance, the enforcement of architecture
policies and principles, and the procedures that integrate the EA process with the Capital Planning and
Investment Control (CPIC) process. An efficient and effective EA provides the common ground where business
and IT people can collaborate, make decisions, and set the direction of the organization.
