Principles are high level statements of the fundamental values that guide business and technology decision-making and activities and are the foundation for architecture, standards, and policy development.
They are stable enough to withstand technological and process changes but timely enough to maintain a clear relevancy with markets, policy, program, and management changes.
Principles consist of the principle statement, rationale, and implications. Though the wording for principles should remain consistent, the rational and implications will evolve over time, as an organization responds to factors such as the current IT environment, internal initiatives, external forces and markets, and changes in mission, vision, and strategic plan.
Below are two example principles:
Optimum Enterprise Benefit
Architectural decisions will maximize the overall benefit by balancing the following criteria: accessibility, consistency, cost, diversity of business needs, flexibility, functionality, manageability, precision, risk, scalability, security, supportability and value.
Reusability of Components
The enterprise will be built on loosely-coupled, reusable modular components that implement services.
