Evaluate the plan. A leader influences the performance of the group and individual members through his or her actions. A group needs control as an engine needs a throttle-to keep it from running itself into the ground. A group works together best when everybody is headed in the same direction. If a plan is to e properly carried out, someone must lead the effort.
Control is a function that the group assigns to the leader to get the job done.
Control happens as a result of recognizing the difference between where the group is and where the group is going. The leader is responsible for developing a plan to help the group get to its goal. Setting the example is the most effective way of controlling the group. Know what is happening and the attitude of the group. Make your instructions clear and pertinent.
