When a project team is assembled in preparation for a large scale project to get underway, what is absolutely essential up front is to establish and determine the person who will be responsible for managing the project team, as it is essential to have a single voice to speak for and represent the team’s ideas, and also control and harness the activities of the team, which improves productivity and cohesion of the team process. Specifically, the concept of manage project team refers to the project management process that involves the actual tracking of the performance of each individual team member, providing any necessary feedback in regards to that performance, resolving any issues that may have arisen in the process to date, as well as coordinating and implementing any changes that may need to take place for the sake of enhancing the performance of the project team from the current point forward.
