We are currently working on how to best manage our projects in TFS 2012. We are planning to create multiple team in order to manage concurrent iteration on the same project for distinct feature not released at the same time so we did two team (Project 1, Project 2).
The problem we currently have is how can I manage team member capacity when assigning a member to multiple Team. Is ther a way to view Capacity assign to a member for all current iteration of every team without navigating between multiple sprint?
What you want is not supported with the current tools, nor have we plans as for now to support this in the near future.
Feel free to add your suggestion to User Voice. We use that list to help prioritize our work.
