Great to share your insights Carl, especially the openness about what caused things to work less well :) Kotter has been my best (virtual) mentor for years too. Also like your comment from Dean... 'Why do we have Project Managers? to push/pull value across silos' :)
The initial organization chart presented during the video has nothing to do with but with operational areas of hierarchy and responsibility. They are not developed to address processes (now Value streams and added values)
