Using a project start time of 0 (or May 15) and a required project completion time of 180 days (or November 15), calculate the ES, EF, LS, and LF times and total slack for each activity. If your calculations result in a project schedule with total negative slack. 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. Also, determine the critical path and identify the activities that make up the critical path.
