A) The critical path is the shortest of all paths through the network.
B) The critical path is that set of activities that has positive slack.

E) The critical path is that set of activities that has negative slack.

Question

Quizplus · Accepted Answer

The critical path in CPM (Critical Path Method) is defined as the longest path through the network, which determines the shortest possible duration to complete the project. Activities on this path have zero slack, meaning any delay in these activities will delay the project. The statement that all activities on the critical path have their Late Start (LS) equal to the maximum Earliest Finish (EF) of all immediate predecessors is true because it ensures that these activities start as late as possible without delaying the project, which is a characteristic of activities on the critical path.
