CST Project Management & Planning 2

Question 1

Which scheduling technique uses probabilistic time estimates (optimistic, most likely, pessimistic) to calculate expected activity durations?

Accepted Answer

PERT

Answer

PERT (Program Evaluation and Review Technique) uses three-point estimates to account for uncertainty in activity durations.

Question 2

In project scheduling, what does 'total float' represent?

Accepted Answer

The amount of time an activity can be delayed without delaying the project finish

Answer

Total float is the amount of time an activity can be delayed from its early start without delaying the project completion date.

Question 3

A project manager needs to compress the schedule by overlapping activities that were originally planned sequentially. This technique is called:

Accepted Answer

Fast tracking

Answer

Fast tracking involves performing activities in parallel that would normally be done sequentially, accepting increased risk.

Question 4

Which WBS element represents the lowest level of the Work Breakdown Structure where cost and schedule can be monitored?

Accepted Answer

Work package

Answer

A work package is the lowest WBS level at which cost and schedule are tracked and managed.

Question 5

When a project schedule shows a Scheduled Performance Index (SPI) of 0.85, this means the project is:

Accepted Answer

Behind schedule, accomplishing only 85 cents of work for every dollar planned

Answer

An SPI below 1.0 indicates the project is behind schedule; 0.85 means only 85% of planned work has been accomplished.
