There is considerable value in constant membership in the group. New members being added or old ones dropping out affect the group's psychological and sociological structure. Members get to know each other, develop positive attitudes, and build a trust relationship that affects the group's communication and productivity. Stages of becoming a group Time and active participation are essentials for group development. Such group development can be observed by behavioral changes in the group.
Most new groups are very dependent on a leader.
The leader may be assigned by the appointing body or elected by the group. Such a leader may gain control of the group, direct its activities and assume much of the responsibility. If a controlled type of leadership continues, the group's productivity will be limited to the leader's skills. Group maintenance and participation may be a problem. Inexperienced members may be reluctant to accept responsibility.
