Seven integrated stages that run from scoping the development cycle through to managing enterprise architecture requirements, supported by the EA principles, the national reference models, the EA content metamodel, and EA governance.
Where this page sits in NORA: Section II — National Enterprise Architecture Methodology.
Each stage builds on the one before it and applies across all six domains. The methodology is a continuous practice that does not stop when the roadmap is delivered.
Managing EA requirements is the continuous thread that ties the methodology stages together, and the main enabler for governing and tracking how EA domains are documented and developed. Publishing and delivering the roadmap does not mark the end of the methodology. It is a continuous practice that keeps pace with the entity needs as they evolve.
The methodology rests on four supporting elements: EA principles, the national reference models for EA, the EA content metamodel, and EA governance. All four are set out in the Guideline for Implementing the National Enterprise Architecture Methodology issued by the Digital Government Authority (document number DGA-1-2-5-230).
