The project network is shown below:

The project completion path is along A-C-E or B-D-E
Duration along path A-C-E = 2 + 1 + 3 = 6
Duration along B-D-E = 4 + 6 + 3 = 13
Since, longer time is along B-D-E,
The critical path for the network activities is along B-D-E with duration 13.

A simple CPM network has three activities, A, B, and C. A is an immediate predecessor of B and of C. B is an immediate predecessor of C. The activity durations are A=4, B=3, C=5. The network has no critical path. The critical path cannot be determined without knowing PERT expected activity times. The critical path is A-C, duration 10.5. The critical path is A-B-C, duration 9. The critical path is A-B-C, duration 12.
