2. (2 points total, 70% content, 30% communication quality). Using the data in the table below: a. Create the precedence diagram for the project b. Develop a project schedule (as represented in a Gantt chart) assuming all activities must begin as early as possible. c. The department manager does not like pulling her employees on and off projects. Instead, she wishes to assign eight people full-time to the project starting at the beginning of the project. However, once team members are no longer needed for the remainder of the project, they may be reassigned. In effect, employees may initially be paid even though they are idle, but once project labor requirements fall permanently below eight persons, employees may be removed from the project. If project labor requirements exceed the number of available personnel (i.e., eight persons) in any given week, overtime will be used. Determine total project labor cost for the project schedule (Gantt chart) in part b, assuming each employee is paid $1500 per week and overtime is paid at time and a half. d. Consider activity slack to develop a new project schedule (Gantt chart) with lower labor cost, without affecting overall project duration. Attempt to find the minimum cost schedule (Gantt chart).
