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 the critical path should also be determined. Here are the activity times: Activity Time (weeks) Immediate Predecessor(s)
A 4 -
B 5 -
C 6 A, B
D 4 B
E 10 C
F 8 C, D

Assume the project completion time is 19 weeks. Please find out ES, EF, LF, LS and total slack time for each activity. Please also identify the critical path.

(Note: you can create a table in the excel as below. Once you are done, copy the table to the space provided here).
