Cohesiveness
refers to the extent to which members of a group are motivated to remain together. A group where members enjoy working together and eagerly pull together and are contented with being members is highly cohesive.
A group with low cohesiveness is one where members do not like to be together and are eager to leave the group. High cohesiveness may result from small size, clear goals and constant interaction. The results are that group members are highly motivated and there is goal attainment.
Low cohesiveness may be due to large size, ambiguous goals and roles and little interaction and the result may be low goal attainment, low morale and death of the group.
