a. Develop an estimated duration for each activity. b. Using a required project completion time of 180 days 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 . 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.
