Develop an estimated duration for each activity.
2. Using a project start time of 0 (or January 1) and a required project com-pletion time of 180 days (or June 30), calculate the ES, EF, LS, and LF times and TS for each activity. If your calculations result in a project schedule with negative TS, revise the project scope, activity estimated durations, and/or sequence or dependent relationships among activities to arrive at an accept-able baseline schedule for completing the project within 180 days (or by June 30). Describe the revisions you made.

3. Determine the critical path, and identify the activities that make up the crit-ical path.

4. Produce a bar chart (Gantt chart) based on the ES and EF times from the schedule in item 2
