Critical Path and Scope

Expected Critical Path

The expected critical path is the path with the longest expected length.

highlighted = computed this step

Longer path

A-B-D has expected length 7, which is longer than the other path's 19/3.

Expected critical path

The expected critical path is A-B-D.

Critical note

Critical here means longest expected path in this small model.
