A simple project listing of five activities and their respective time estimates are presented below:
Using CPM, which activities make up the critical path?
There are two paths: A, B, D, E and A, C, D, E. ABDE will take 8 days while ACDE will take 7 days. ABDE, therefore, is the critical path for this project. Activity C is off the critical path because there is one day of slack in that activity.
