Question: Analyze the PERT Chart and discuss, along with reasons, whether it was designed correctly or not.
The above PERT chart is not correct.

2nd reason is that, if it said that activity A & B will complete, than C will be started, so C & D should remain the same to complete that process parallel, but in this chart D is taking much time to complete that tast
