In the following table the activities with their precedence sequence and expected time (weeks) are listed for Lillian Fok's construction project and on the right the precedence network is shown: Activity J KLMNOP The project length is Nodes 1-2 1-3 2-4 2-3 3-4 4-5 3-5 weeks. Time (weeks) 12 2863277

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: Time Activity (weeks) 6 7 ABCO 3 2 Immediate Predecessor(s) A A D Dave's earliest start (ES) and earliest finish (EF) are: Time Activity (weeks) 4 EFGHI 6 10 7 Immediate Predecessor(s) B B C, E D,F

Shown below is the project network diagram for a small office renovation project.  The numbers in the nodes are the activity times. What is the slack time for activity A? 7 5 3 0
