Each project is cutted into a set of tasks. A task may be decomposed into many other sub-tasks. A task is assigned to only one employee. However, an employee may perform many tasks. Some employees are assigned the responsibility to supervise other employees. For each project, there is only one employee nominated as "Project Manager" (PM).
