Do check out Amy the Architect. Its an interesting view on what an architect's role might be. Just to borrow their gist:
Suddenly, it struck Amy: she wanted to be the meaningful link between project decision makers and the technical people on the project.

Conversely, she wanted the decision makers to feel confident that they had access to all the information they needed in a form they understood and believed to be what their technical staff really wanted to say.
