The Enterprise Architecture Strategy provides the principles, standards that drive the content of the EA Architecture.
These are approved by the Architecture Review Board and are used to guide and support the development and use of all the EA Architecture deliverables.

The prescriptive elements in the EA Strategy describe the principles, goals, objectives, standards and guidelines that enforce the enterprise architecture governance and compliance processes.

The remaining elements in the EA Strategy describe the enterprise architecture reference models (blueprint) that can be used by stakeholders such as the development and delivery projects and IT operations.

EA Decisions and Initiatives

The IT Strategy is not explicitely written as a single document but is instead realised by the content of the future state Enteprise Architecture.
In this way the future state Enterprise Architecture acts as a bridge between the systems developed, acquired products that are integrated and the implicit IT Strategy.

See the Strategy Matrix for a mapping of the strategic decisions, activities and changes, against the six architecture domain models.

See the list of Architecture Initiatives that will implement the strategic architecture decisions.
See the Architecture Roadmap with details of the architecture initiatives that will evolve the current state Enterprise Architecture towards the target state Enterprise Architecture.
