Finding your inner Zachman

The last couple of weeks I have been working on applying the Zachman's framework for enterprise architecture to two projects. I have been struggling through the first row and then skipped around a bit. I think I have found the part of the project (any project) I am most passionate about.... Working with Human Interface Architecture and explaining it as a designer to the builder of the Presentation Architecture. In my mind this level needs to be closely related to the Business Process Model and to the List of Business Goals/Strategies.

Where do I see myself most helpful in the large project...
