Enterprise Architecture Good Practice Guide First International Open Standard in EA
January 2009
The purpose of this First International adapted is to provide guidance to organization's in initiating, developing, using, and maintaining their enterprise architecture (EA) practice. This Open Standard guide offers a set of Enterprise Architecture Good Practices that have proven their benefits to organizations and that addresses an end-to-end process to initiate, implement, and sustain an EA program, and describes the necessary roles and associated responsibilities for a successful EA program.
Enterprise Architecture is a complete expression of the enterprise; a master plan which “acts as a collaboration force” between aspects of business planning such as goals, visions, strategies and governance principles; aspects of business operations such as business terms, organization structures, processes and data; aspects of automation such as information systems and databases; and the enabling technological infrastructure of the business such as computers, operating systems and networks.
While EA frameworks and models provide valuable guidance on the content of enterprise architectures, there is literally no guidance how to successfully manage the process of creating, changing, and using Enterprise Architecture.
