The finished scheme is not an architecture; its a tool helping manage and organize one. [] The elapsed time required to produce the architecture makes it close to obsolete before completion. The people responsible for this seamless transition are enterprise architects.

In light of the abundant previous negative research findings regarding formal architecture methodologies13, 14, 15, the failure of FEAF can be viewed as a natural, perfectly predictable and even the only possible outcome. The Zachman Framework is a product of John Zachman who has been championing this cause for at least 15 years, first with IBM and then on his own.
