It requires leadership and managerial qualities to control a team, which are gained both by study and experience. It is important to have a clear vision of goal of your team and an effective plan and resources to complete it. The responsibility to execute the plan lies with team leader but it is his ability to transfer or share it with all the team members and develop the same sense in them. In a team performance all the members need to perform their assigned role to achieve the target. After completing any task, a review needs to be done with all the team members in order to know their strength and shortcomings.
It is important to have an effective communication between the team members and it is the responsibility of team leader to clearly assign responsibilities to the other members. It is important to lead by example for the team leader. Team leader acts as a shock absorbent for the team members taking the pressure from top management to himself and preserving his team members from it. He also should have the morality to give credits for achievements to his team members in order to motivate them.
