Enterprise Architecture delivers overview of the current state of IT,
establishes vision for a future state, and finally generates strategy to move from the current state to the desired state.

- Are we doing the right things?
- Are we doing them the right way?
- Are we getting them done well?
- Do we expected benefits?
Basically Enterprise Architecture delivers information on how an enterprise achieves its strategy.
