It determines the earliest time each activity can start and finish and determines the total duration of the project.

It determines the latest time each activity can start and finish without delaying completion of project. It also helps determine the activities that can be delayed or not.

What is CPM?

Critical path in network gives ___ to complete the project.

In Critical Path Method, the project completion period is the EF of last activities.

Changing the duration of a critical activity will not affect the overall completion time.

The starting activities that have no predecessor cannot be carried out in parallel.

Changing the duration of a non-critical activity will not affect the overall completion time, provided the revised float is positive.

The backward pass calculation cannot proceed if the forward pass had not completed.

The critical path activities can be identified only after all the floats were determined.

To start the backward pass computation, the LF is equal to EF for the last activity.

In Critical Path Method, the project completion period is the sum of all of all activities duration.
