Activity on Node Network Start A B C F E 0 12 D 42 0 End Critical activities are activities that cannot run late. For critical activities: Earliest start time + length of activity = Latest finish time

Activity on Node Network Start A B C F E 0 12 D 42 0 End The green arrows mark the critical activities, which form the critical path. The critical path(s) must form a continuous route from the start node to the end node.
