Once upon a time I coached one of the most amazing agile scrum teams. They were able to deliver things that their management found quite unbelievable so much so that they conveyed a meeting to find answers to why this particular group of people were able to so greatly outperform others in the organization. As an aside I was not originally invited to the meeting but the team lobbies for me to be there as they considered me one of the team and, as a team member, partially responsible for their success.
