To a large extent, the leader determines group structure and the success of the team. The leadership style is different in groups and teams, as team leaders share the responsibility as they empower the team members. The quality of team leadership, whether from the formal leaders or other team members (like you), is becoming increasingly important as it affects team performance.

Here are the benefits of setting objectives; they apply to both individuals and groups, and teams set their own objectives. In groups, however, the objective is commonly very broad—usually to fulfill the mission. Part of a leader’s responsibility is to be sure the size and composition of a group or team is appropriate for the situation. Realize that in both formal and informal groups and teams, there are official and unofficial leaders. Group structure dimensions include type, size, leadership, and objectives.
