LEARNING OBJECTIVE
- Calculate critical path, project float, early start dates, and late start dates.
The critical path is the path through the network that results in the latest completion date of the project.
If any activity on the critical path is delayed, the completion of the project will be delayed by an equal amount. It is the path with the greatest total duration. To determine the critical path, add the amount of time estimated for the duration of each activity to the previous activity to determine which path through the network has the longest total duration, as shown in Figure 8.12. Durations are indicated in days. The critical path through these tasks takes at least eight days. Activities on the critical path are shaded.
