Peopleware: Gelled teams have a common goal
Prior to a team’s jelling, the individuals on the team might have had a diversity of goals. But as part of the jelling process, they have all bought into the common goal. (DeMarco and Lister 2013, chap. 21)
The purpose of a team is not goal attainment but goal alignment. (DeMarco and Lister 2013, chap. 21)
