Project Management Flashcards

In a Critical Path Method (CPM) schedule, which statement best describes the critical path?

Answer: The longest path through the network, usually with zero total float

The critical path is the longest-duration sequence and sets the project finish date, so its activities typically have zero float.

Total float for an activity is best defined as:

Answer: The time the activity can be delayed without delaying project completion

Total float is how long an activity can slip without moving the project's finish date.

A project manager overlaps ductwork installation with the final phase of structural steel to recover schedule. What is this technique called?

Answer: Fast-tracking

Fast-tracking runs activities in parallel that would normally be sequential, which raises the risk of rework.

Adding a second shift of pipefitters at extra cost to shorten a critical activity is an example of:

Answer: Crashing

Crashing shortens duration by adding resources, usually at extra cost.

In a finish-to-start (FS) relationship, what must happen before the successor activity can begin?

Answer: The predecessor must finish

Finish-to-start, the most common dependency, requires the predecessor to finish before the successor starts.

What duration does a schedule milestone such as 'Substantial Completion' typically have?

Answer: Zero duration

Milestones mark significant points in time and have zero duration.

Which scheduling technique adjusts start dates to smooth out peaks in crew demand, possibly extending the schedule?

Answer: Resource leveling

Resource leveling reschedules activities to resolve over-allocation and can lengthen the critical path.
