As usual, Dustin Boscher, our visualization king, takes things to the next level when defining how to use visualization tools in a formal project setting. He has a post over on our BPM blog about where and how visualization fits. Check out the link for the text around it. My only comment is that I believe his approach works in a SCRUM type setting.
My only comment to Dustin is that he should come post for the portal and social guys, we are much more fun than those process guys………………..
