David Chesnut, a fellow writer on the Team System content team, has posted an early draft of the Process Planning Guide. See his post for the details:
Hi, my name is David and I'm a programmer/writer on the Visual Studio Team Foundation team. I was recently asked to write a guide for administrators that would help them take into consideration the role of process when planning a new Team Foundation server, or when creating a new team project. Each team project can use a different process, and which process you choose determines the reports, queries, areas, iterations, and other settings for a team project.
