Activity Preceding Time A -- 8 B -- 4 C A, B 7 D A, B 3 E C, D 5 F C, D 6 G E, F 4   Draw the project network diagram. Calculate each activity's ES, EF, LS, LF, and Slack using the project activity nodes on the project network diagram. What is the project completion time? Identify the critical path
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.
