Using a project start time of O and a required project completion time equals project deadline minus current date (for example the project is due by August 31, 2020; and today is July 01, 2020; the required project completion time is 61 days). Calculate the ES, EF, LS, LF time, and slack time for each activity. If your calculations result in a project schedule with negative slack time, revise the project scope, activity estimated duration, and/or sequence or dependent relationships among activities to arrive at an acceptable baseline schedule for completing the project within the completion time.
