Определение Enterprise Architecture от NASA CIO

"...a simple definition for Enterprise Architecture that is not spoken in the dribble of IT jargon.

• In simplest terms, it is a planning framework that describes how the technology assets of an organization connect and operate.
  
  
• It also describes what the organization needs from the technology.
  
  
• And finally, it describes the set of activities required to meet the organizational needs.

Oh, and I should also say it operates in a context of a process for setting priorities, making decisions, informing those decisions, and delivering results called - IT Governance. "
