Six main domains plus strategic alignment as a cross-cutting element. Each domain has a national reference model and DGA guidance.
The development cycle begins with Business Architecture as the primary entry point and flows through the domains, while Security Architecture acts as a cross-cutting domain that covers all components.
Strategic alignment is a cross-cutting element in the general component model. It links entity objectives, digital transformation strategy, and EA outputs across all six domains.
The national methodology applies each domain's requirements independently within an integrated development cycle. Each domain has its own national reference model.
