Turns out a former co-worker of mine was a contributor on the TFS Guidebook I recently blogged about. Jason Taylor and I worked together back in my Windows days on a virtual team looking for ways the various test orgs around the Desktop Client division could work together, share tools, and generally be more effective. He was also a huge proponent of model-based testing and contributed significantly to the tools we use inside Microsoft for MBT. Unfortunately for Microsoft, Jason left about 4 years ago to work with Security Innovations. Check out his blog, "The Good Life" for some great thoughts on effectiveness, Team System, and Team Foundation Server.
