This book does an OK job at explaining what it needs to do. Unfortunately, it does not go terribly in depth into many topics. I bought it mainly to learn about editing the work items, processes, and so on, and it did not give me the information that I needed. It also does not seem to be very clear about what stuff applies to TFS 2008 and what applies to TFS 2005. Like far too many Microsoft Press books, it just feels like it is aimed at an architect or business analyst, but not at someone looking to accomplish real work.
