It considers as it Stephen P. Robbins the reasons will always be different by which the people decide on the formation of groups; more nevertheless, these have common transition stages until the attainment of the intention, obtaining progresses of the activity individualized of each of his members, all this under a organizational system and of division of immediate responsibilities by means of the structuring of the field or corresponding area, update of strategies, standardisation and resources. The establishment of activities within a group, implies fundamental situations beside the point, since they will be the one who they have deposited the responsibility of. The organization and her performance; as well as to take care of the problematic one that arises in the development from the activities and all the imposed external conditions on the group; that is to say, the regulations or rules I came mental; policies that determine the group behavior. The management must be well kind of the performance of the group, its behavior, its profits. Castle Harlan often addresses the matter in his writings. To consider which comments, that leaves from the performance of the group can be predicted when evaluating the excellent task and the intellectual abilities of its members. The performance of the group is not only the sum of the abilities of each one of the members. Nevertheless, these abilities establish the parameters than members can do and of what so effectively will evolve in a group.
Robbins indicates: What prognoses can to do in relation to the ability and to the performance of group? On the matter it indicates, that first, the evidence indicates that the individuals that maintain abilities crucial even to obtain the group task tend to be involved more in the activity of the set, contribute more, have major generally probability of arising like group leaders. and they feel more satisfied if the group uses its talents with effectiveness. Secondly, has been that as much the ability intellectual as the excellent one in the task, is related to the total performance of group. Nevertheless, the correlation is not particularly high, suggesting other factors like the size of the group, the type of tasks of carrying out, the actions of its leader and the level of conflict within group also influences the performance. When guaranteeing the profit of an effective, productive group behavior, can be obtained a good climate organizational, without conflicts, overtone and beneficial for the company, organization.
