Constructing the Critical Path

1. LO 9.5 Construct the critical path for a project schedule network using forward and backward passes, determine project slack, and calculate the probability of finishing on time.

The next step is to link activity duration estimates and begin construction of the critical path. Critical path calculations link activity durations to the preconstructed project activity network. This point is important: the project network is first developed using activity precedence logic, then, following task duration estimates, these values are applied in a structured process to each activity to determine overall project length. In addition to allowing us to determine how long the project is going to take, applying time estimates ...
