I came across the information from the latest MSDN Flash.  The information contained is awesome.  Finally you have a guide to show you how to implement TFS into an organization.  I believe the MSDN Flash states it perfectly

“It’s a collaborative effort between patterns & practices, Team System team members, and industry experts that shows you how to incrementally adopt TFS for your organization. “

There is also a related Visual Studio Team System Guidance Project
