Critical Path Method (CPM)

What is critical path method (CPM)

• a step-by-step project management technique for process planning that defines critical and non-critical tasks
• a graphical display of project activities that helps the users understand the relationships among the activities.
• a project management tool to illustrate how the project will run.
• A graphical colourful displayed graph

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

• Forward Pass

• Backward Pass

• Side Pass

• Critical Path

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.

• Forward Pass

• Backward Pass

• Side Pass

• Critical Path

What is CPM?

• critical process method

• critical path activity

• Critical path method

• critical process activity

Critical path in network gives ___ to complete the project.

• Critical time

• Longest time

• Shortest time

• Production time

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

• True

• False

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

• True

• False

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

• True

• False

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

• True

• False

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

• True

• False
