Teamwork requires collaboration, open-mindedness, shared leadership, focus, respect, persuasion, cooperation, and effective communication from all members. For a group to be considered a true team, members must have individual and mutual accountability, focus on team goals rather than individual goals, and shape their purpose, goals, and approach together rather than relying solely on a manager. Key differences between work groups and teams are that teams have stronger collective focus, mutual accountability, and shape their work jointly to achieve shared goals.
