Dave Fletcher was able to determine the activity times for constructing his laser scanning machine Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined Here are the activity times. Activity Time (weeks) Immediate Predecessor(s) Activity Time (weeks) Immediate Predecessor(s) A E B F G D H Dave's earliest start (ES) and earliest finish (EF) are: Dave's latest start (LS) and latest finish (LF) are 5 7 4 1 A A Activity A u G I UDEF I F B Activity H G H ES 0 0 5 7 21345 LS EF 5 9 12 22 20 LF 5 6 10 7 B B S C, E D, F k

Thank you for your help, it is much apprecaited.

Dave's latest stant (LS) and latest tinish (L.F) are The slack times ate The activities on the critical path are The total project completion time for Dave = weeks
