The VSTS team are working on some test planning for the next release of Team Foundation Server. One area they’re focused on is testing various possible configurations of TFS.
MS is trying to get a picture of the variety of ways that people have their TFS installations configured. Read Chris's blog post on what they are doing and why. There is a short survey (10 questions) with no need to provide any sensitive data. Fill it out and help them to make sure that the configurations they test map to ones actually deployed ‘in the wild’. If you own or manage multiple TFS deployments, you can fill out the survey once for each.
So go and fill out the 10-question survey here for each deployment you have.
