Define EA principles to guide target enterprise architecture definition, solution development, acquisition, and operation.
EA principles are rules that inform and restrict architecture and solution design. EA principles are developed with the intent of being long lasting and rarely modified.
EA principles are informed and constrained by enterprise principles. Enterprise principles provide a basis for harmonizing decision-making across an organization and are a key element of enterprise governance.
Hold working sessions with the EA capability optimization project team and relevant EA capability stakeholders to define and document EA principles with the following attributes:
- Name. Represents the essence of the rule and is easy to remember.
- Statement. Communicates the rule succinctly and unambiguously.
- Rationale. Describes the business benefits and reasoning for establishing the principle.
- Implications. Should highlight both business and IT requirements necessary to carry out the principle.
Group EA principles by relevant EA domains: e.g. Business, Information, Application, and Technology.
