IA documents, research and process diagram

I like Peter Van Dijk's diagram on his blog titled Research, deliverables, process and the team (updated by Dan Wendling). In it, Peter diagrams how IA research and deliverables relate to the development cycle and the team members involved in the process. It's shows how elements of a development process relate organically to one another, where the dependencies are, and who is involved as the project moves from top to bottom in space/time. And he avoids the venn diagram doing it.
