Sample on Introduction To Management

The term team development states that it is essential for individual to learn through understanding the team roles and thus through examining the patterns of change and continuity in groups over time. Thus, in order to effectively understand the process of team development, individual should undergo various stages of team development through referring to the Tuckman's team development theory that helps in overcoming the conflicts during the process (Gallagher, 2013).
