Subsequently managers have adopted a variety of means to influence the activities of groups so as to harness them in support of managerial goals. One such measure is basing pay or bonuses on group output, so as to provide a stimulus to group members to work effectively together and to pressurize recalcitrant members into following group policy. Similarly, the creation of ‘semiautonomous work groups’ (see JOB DESIGN AND REDESIGN) with the power to allocate group members' tasks is designed to heighten both group cohesion and commitment to effective task performance. However, a question that still nevertheless vexes managers is why some groups are effective whilst others are not. For this reason substantial research has been conducted into group development and dynamics (i.e. the stages of growth that they go through and the patterns of interaction within them). One approach has suggested that groups go through four stages of development:
Whilst team working is generally thought to be a useful approach to achieving organizational goals, it can have negative effects. The most damaging of these is groupthink, where pressures towards group conformity stifle creativity. See TEAM BREIFING.
