Develop an estimated duration for each activity. Using a project start time at 0 (or Jan. 1) and a required project completion time of 180 days (or Jun 30), calculate the ES, FS, and LF times and TS for each activity. If your calculations result in a project schedule with negative TS, revise the project scope, activity 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 Jun 30). Describe the revisions you made. Determine the critical path, and identify the activities that make up the critical path. Produce a bar chart (Gantt Chart) based on the ES and EF times from the schedule in item 2.
