1. Group Size and Roles managers need to take group size, group tasks, and group roles into account as they create and maintain high-performing groups and teams.
GROUP SIZE number of members in a group can be an important determinant of members’ motivation and commitment and group performance. Advantage of small groups with 2-9 members: interact more with each other and find it easier to coordinate their efforts, be more motivated, satisfied, and committed, find it easier to share information, and be better able to see the importance of their personal contributions for group success. Disadvantage members of small groups have fewer resources available to accomplish their goals.
Advantage of large groups with 10 or more members: they have more resources at their disposal to achieve group goals than small groups do. also let managers obtain the advantages stemming from the division of labor. Disadvantage the problems of communication and coordination and the lower levels of motivation, satisfaction, and commitment that members of large groups sometimes experience
GROUP ROLES a group role is a set of behaviors and tasks that a member of a group is expected to perform because of his or her position in the group. in forming groups and teams, managers need to clearly communicate to group members the expectations for their roles in the group, what is required of them, and how the different roles in the group fit together to accomplish group goals. Managers also need to realize that group roles often change and evolve as a group’s tasks and goals change and as group members gain experience and knowledge. Managers should encourage group members to take the initiative to assume additional responsibilities as they see fit and modify their assigned roles, this process called ROLE MAKING.
