Agile teams are like football teams working towards a commonly understood goal. I have been part of agile teams for some years and the key is effective and efficient communication across all stake holders. Managers/Scrum masters are mere facilitators of the team and traditional management/micro management will kill the team's spirit.

In the teams I have worked, we are encourage to play team games after work hours to improve the camaraderie within the members. I have collected those thoughts here.
