Slack = LS-LF=EF-ES
Critical path is the longest path which is A-C-F-G-H with duration of 51 days
It will take 51 days to complete the project
Activity E has slack of 9 days so E can be delayed by maximum 9
days without delaying the completion of the project

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.

Which one is not correct about the critical path method (CPM) in project management? Duration of a project is equal to the duration of its critical path. There could be more than one critical paths. Crashing a project is shortening the duration of the critical activities. The tasks on the critical path can be delayed without delaying the project duration. Slack times of activities on a critical path are zero.
