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.
The Business Strategy is a key business planning deliverable that defines what an organisation plans to do in order to obtain a competitive advantage in its chosen markets (check my article entitled "Business Strategy" for further details : http://bit.ly/23Uw7EM)
The IT Strategy is a key IT planning deliverable that defines how the IT department in an organisation will operate in order to deliver the required services to the rest of the organisation.

- Is about consequences → A strategy has major consequences. When is a decision strategic ? When it is irreversible ?

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.
