The primary purpose of an Enterprise Architecture (EA) is to inform, guide, and constrain the decisions for the enterprise, especially those related to IT investments.
The true challenge of enterprise engineering is to maintain the architecture as a primary authoritative resource for enterprise IT planning. This goal is not met via enforced policy, but by the value and utility of the information provided by the EA.
In general, the essential reasons for developing an EA include:
• Alignment—ensuring the reality of the implemented enterprise is aligned with management’s intent
• Integration—realizing that the business rules are consistent across the organization, that the data and its use are immutable, interfaces and information flow are standardized, and the connectivity and interoperability are managed across the enterprise
• Change—facilitating and managing change to any aspect of the enterprise
• Time-to-market—reducing systems development, applications generation, modernization time frames, and resource requirements
• Convergence—striving toward a standard IT product portfolio as contained in the Technical Reference Model (TRM).
Selling EA vs. Building Support
The single most difficult task in delivering and developing and Enterprise Architecture program is gaining support from the enterprise itself. This is why I was so passionate about writing this report. There are many bumps and detours along the way, and if we all can avoid and maneuver them, EA will advance as a whole and become more accepted and understand.
There is little reason to start an EA program itself unless it is supported by the business and treated as a business initiative. It will require executive level commitment and persistence. The IT department should not have to continually go to the well in various user organizations to get their support if there is a good plan and strategy in the beginning.
