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: Immediate Predecessor(s) Time Activity (weeks) A 7 B 6 Time Activity (weeks) E 5 F 5 G 11 Immediate Predecessor(s) B B C, E DF 2 A D 3 A H 7 Dave's earliest start (ES) and earliest finish (EF) are: ES EF Activity A 7 OO B C 9 D 7 E 11 F 6 I G 22 H 18 Dave's earliest start (ES) and earliest finish (EF) are: Activity ES EF 7 A B 0 C 9 D 7 E 1 11 F 6 G 22 H 16 Dave's latest start (LS) and latest finish (LF) are: LF Activity H LS 15 G 11 F 10 E 6 D 12 C 9 B 0 A 2 I The slack times are: Slack Activity . B IT m The activities on the critical path are B-F-H The total project completion time for Dave = 22 weeks
