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:
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:
Activity Time (weeks) Immediate Predecessor(s) Activity Time (weeks) Immediate Predecessor(s)
A 6 - E 5 B
B 8 - F 6 B
C 2 A G 9 C, E
D 3 A H 7 D , F
Dave's earilest start (ES) and earliest finish (EF) are:
Activity ES EF
A 0 6
B 0 ?

A network diagram shows the sequence of the task that is done to complete a project. It usually shows the link of each task with the duration taken by each activity with respect to the completion of the project. Each task is shown with the nodes that are connected with each other with the help of arrows. There are 2 types of network diagrams:- CPM and PERT.
