you ask who is successfully implementing the whole framework, the answer is nobody that we know of yet" There are no detailed examples demonstrating the successful practical application of the framework EA practitioner Stanley Gaver argues that "the analogy to classical architecture first made by John Zachman is faulty and incomplete" Jason Bloomberg argues that "enterprise isn't an ordinary system like a machine or a building, and can't be architected or engineered as such" A detailed scrutiny demonstrates that the Zachman Framework is actually based only on purely speculative arguments, promoted with fictional promises, has no practical use cases and, from the historical perspective, didn't introduce any innovative ideas missing before This criticism suggests that the Zachman Framework can hardly reflect actual best practice in EA.
