A: to manage projects involves heavy workload and requires much of the company’s energy and human resource. However by using teamwork we can make this complicated work become simple and easy. First when we set up a project-oriented teamwork all members of the projects are united and work in a teamwork spirit. That means they work more systemically and coordinate more with each other. As leaders we won’t worry about the time we will have to waste on the coordinating procedures anymore. Second by using teamwork we can create a sound and effective communication with the project and monitor the communication between members as well as the communication between boss and subordinates. Third in a team everyone tries to help others in their work and a lot of problems can be solved quickly after they occur. The managers can thus save the energy and time for trouble-shooting.
