I have worked with Jim on and off over the past year and he is one one of those people you do not forget working with. Enough said about that.
Early on he had a lot of questions related to ROI Calculations and Business Alignment. Over time he brought me closer to his view of Business Alignment and I convinced him that ROI Calculations were at best lies codified by rigorous technique. It is always a pleasure when you learn from someone you are coaching.
I think he is Agile for life...Time will tell.
