Goals are guidelines for actions. It is through group goals that the efforts of group members are planned and coordinated. Conflicts among group members are resolved on the basis of what assists the groups in achieving its goals. Setting goals gives you an opportunity to review and evaluate what's been done and to discuss problems. Goals provide a measuring stick against which progress can be directed.
Goals are the motivating force in the behavior of group members.
Without motivation the group takes no action to achieve it's goals. Achievable goals are perceived as realistic, plausible and possible. Review goals periodically at meetings and check them off when you have accomplished them. Make your goals known to those you work with. Commit yourself publicly.
