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:

A - 5 weeks, no immediate predecessor

B - 7 weeks, no immediate predecessor

C - 3 weeks, A immediate predecessor

D - 1 week, A immediate predecessor

E - 5 weeks, B immediate predecessor

F - 5 weeks, B immediate predecessor

G - 9 weeks, C,E immediate predecessor

H - 7 weeks, D, F immediate predecessor

What are Dave's earliest start and earliest finish for each Activity A-H

What are Dave's late start and latest finish for each activity A-H?

What are the slack times for each activity A-H?

The activities on the critical path are?

The total project completion time for Dave is how many weeks?
