a. Develop an estimated duration for each activity.
b. Using a project start time of 0 and a required project completion time of 180 days (or June 30), calculate the ES, EF, LS, and LF times and total slack for each activity.
If your calculations result in a project schedule with negative total slack, revise the project scope, activity estimated durations, and/or sequence or dependent relationships among activities to arrive at an acceptable baseline schedule for completing the project within 180 days (or by June 30). Describe the revisions you made.
c. Determine the critical path and identify the activities that make up the critical path.
d. Produce a bar chart (Gantt Chart) based on the ES and EF times from the schedule in item 2.
