Hot off the presses... one of the most common requests we get from customers adopting Visual Studio Team System is for more guidance. The patterns & practices team has delivered once again. From J.D.'s blog post:

Today we release the final version of our patterns & practices: Team Development with Visual Studio Team Foundation Server.  It's our Microsoft playbook for Team Foundation Server.  It shows you how to make the most of the Team Foundation Server.  It's a compendium of proven practices, product team recommendations, and insights from the field.

It's nearly 500 pages long so think twice before you send it to the printer, but there's a lot of really great guidance in here which I think will address the vast majority of questions I get every day from customers.
