This position comes directly under the CIO. The CIO is responsible to "ensure alignment of IT with "current and/or future structure and behavior of organization’s processes, information systems, personnel and organizational sub-units, aligned with the organization’s core goals and strategic direction" but it’s the “Architect” who’s responsible to blueprint and develop the vision that mates IT & business into a cohesive, functioning and productive unit, the EA is a living, breathing document that looks out into the future but also takes the present into account, or it should.

AND, there is also the opportunity for Enterprise Security Architects (my next position) who does more or less the same thing with blueprinting security into systems and business processes.
