A real team, in my view, is something very specific. It differs from the more common “single-leader unit” in three important ways. First, all members of a real team have an equal level of emotional commitment to the team’s purpose and goals. Second, the leadership role shifts easily among the members based on the skills and experience they have and the challenges of the moment, rather than on any hierarchical positions. Third, the team members hold one another accountable for the quality of their collective work. Members of real teams subordinate their formal affiliations, personal prejudices, and loyalties to the team’s purpose and goals.
