the definition the same in all five frameworks?

Q1)  What is architecture governance in TOGAF, DoDAF, FEAF, Zachman, and EA3  Cube? Is the definition the same in all five frameworks? Why, in your  opinion, is architecture governance important (or not) to an EA program  and EA initiatives?

Q2)  Based on your readings this week, along with any experience you may have  or extra research you may have done, how would one best use TOGAF or  DoDAF, or FEAF, or Zachman, or EA3 Cube and either COBIT or ITIL for a  well-rounded, sustainable architecture governance framework?
