The EA Board (EAB) consists of business and technical members. The EAB conducts technical reviews and answer the following types of questions in support of IT governance:
- How does the proposed system align with mission, vision, strategy, and goals (for example, how does the proposed change fit within the strategic, tactical, and operational plans of the organization)?
- How will information be shared across the enterprise and with its partners (for example through use of metadata and repositories)?
- How will the system be interoperable (for example, through open standards and modular components); also, are there any existing systems in the organization that can meet the needs of the user?
- How will technology standardization and simplification be met (for example, through use of approved enterprise products and standards)?
- How will performance be measured (for example, what indicators will be used and what represents success)?
- How will information be secured (for example, does the system have authority to connect and authority to operate)?
- How is compliance being met for such things as the Privacy Act, Federal Records Management Act, Section 508 of the Rehabilitation Act, and Federal Information Systems Management Act, and so on?
The EAB provides its finding and recommendations to the IT Investment Review Board (IRB), which has decision authority for all phases of capital planning and investment control (CPIC)—select, control, and evaluate. The IRB is responsible for evaluating, authorizing, prioritizing, and authorizing funding for IT investments and then for the ongoing oversight of cost, schedule, and performance of the investment. The IRB manages its investments as a portfolio (i.e. portfolio management) and ensures that the mix of investments meets business objectives and optimizes value (value, risk, and cost) for the enterprise. The IRB cannot do its job without input from EAB (in a sense, the EAB is the technical, working arm of the IRB).
EA has a critical role in IT governance. EA ensures that IT projects, products, and standards align to and comply with the architecture requirements and planning goals of the organization.
