Most VLEs do not understand Agile. Without a Centre of Excellence, Agile-Scrum is doomed to be corrupted, interpreted differently and not able to scale across VLE’s distributed delivery environments. It is worth emphasising that the more distributed your team, the less chance of success you will have with Agile. Co-Location is almost a necessity if you really want to deploy Agile on complex, or medium-sized and above projects.
