I was spending some time over at David Anderson's AgileManagement.net site.
First, check out his interview with Robert Scoble. David discusses the background of his influences from Eli Goldratt and W. E. Deming and how these are being molded into Microsoft Team System. He talks to some detail on managing the development process by actively watching the working queues and discusses the impact this has on software projects.
Next, checkout his webcast on Lean Thinking within MSF4. I had no idea that MSF was going this route.
My previous view on Team System pricing with respect to MSDN subscriptions has been wavering over the past week or so and this may have completely tipped the scales. I will post more on that topic shortly.
