Enterprise Architect - definition
The definition of an Enterprise Architect does not align with what I've encountered for the role. I certainly wouldn't associate them with the phrase "highly technical masters of electronic wizardry". Wikipedia also suggests a less technical slant to such a role (accepted it's not the most reliable source, but it indicates some measure of opinion).
Those I've encountered with such a title are more concerned with processes and high level interaction between components rather than technical details like authentication systems and group policy. I fully accept I may well be wrong, but it would be interesting to know where this definition that is being worked to came from.
