MSF Agile Frame (Workstreams and Key Activities)

When I review an approach, I find it helpful to distill it to a simple frame so I can get a bird's-eye view.  For MSF Agile, I found the most useful frame to be the workstreams and key activities.  According to MSF, workstreams are simply groups of activities that flow logically together and are usually associated with a particular role.  I couldn't find this view in MSF Agile, so I created one:
