1. Using a project start time of 0 (or January 1) 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.
Responses could be presented in a network diagram or in the schedule table format. The project should finish in 180 days. If the original plan is not completed by 180 days, the responses should describe what tasks were revised to meet the required completion date.
2. Determine the critical path and identify the activities that make up the critical path.
Responses can be presented in a list of activity names, highlighted in the network diagram, or highlighted in the schedule table.
