Consensus. Great teams understand the danger of seeking consensus, and find ways to achieve buy-in even when complete agreement is impossible. They understand that reasonable human beings do not need to get their way in order to support a decision, but only need to know that their opinions have been heard and considered. Great teams ensure that everyone's ideas are genuinely considered, which then creates a willingness to rally around whatever decision is ultimately made by the group. And when that is not possible due to an impasse, the leader of the team is allowed to make the call.
