Project Management Learning Objectives: in this assignment the student will demonstrate: Knowledge of project scheduling techniques Ability to find expected times, early start and finish time, slack and critical path for a project. Ability to draw PERT and Gantt charts. Assignment: The following exercises are to be done manually (i.e., without the use of project management software). 1. Given the following task information for a project: Task Optimistic Time Most Likely Time Pessimistic Time Expected Time 3 7 11 B 5 9 13 1 2 9 D 2 3 16 E 2 4 18 F 3 4 11 1 4 7 H 3 4 5 E G Calculate the expected time for each of the tasks and enter into the table above. (taken fromVGH ex. 2.6) 2. Given the following task information for a project: Task Predecessor(s) Expected Duration Early Finish Late Finish Slack Critical Path? 5 B A 3 A 4 D 6 E B, C 4 F D 1 G D, E, F 5 a. Draw the the Pert Chart (network precedence diagram) for this project. b. Find the Early Finish, Late Finish, and Slack for each of the tasks, and identify which tasks are on the critical path (complete the above table). c. Using the earliest start and finish times, draw the Gantt chart for this project
