CST Schedule Compression & Acceleration Techniques

Question 1

What is 'crashing' in the context of schedule compression?

Accepted Answer

Reducing activity durations by adding resources

Answer

Removing non-critical activities from the schedule

Answer

Overlapping sequential activities to save time

Answer

Eliminating float from the critical path

Question 2

Which schedule compression technique involves overlapping activities that would normally be performed sequentially?

Accepted Answer

Fast-tracking

Answer

Crashing

Answer

Resource leveling

Answer

Schedule baselining

Question 3

What is the primary trade-off when using the crashing technique?

Accepted Answer

Increased cost vs. reduced duration

Answer

Increased scope vs. reduced duration

Answer

Increased risk vs. reduced resources

Answer

Increased float vs. reduced milestones

Question 4

When applying fast-tracking, which type of dependency is most commonly modified?

Accepted Answer

Discretionary finish-to-start dependencies

Answer

Mandatory finish-to-start dependencies

Answer

External finish-to-start dependencies

Answer

Mandatory start-to-start dependencies

Question 5

In schedule crashing analysis, the 'crash cost slope' is calculated as:

Accepted Answer

(Crash Cost - Normal Cost) / (Normal Duration - Crash Duration)

Answer

(Normal Cost - Crash Cost) / (Crash Duration - Normal Duration)

Answer

(Crash Duration - Normal Duration) / (Crash Cost - Normal Cost)

Answer

(Normal Duration + Crash Duration) / (Normal Cost + Crash Cost)

Question 6

Which of the following is a primary risk associated with fast-tracking?

Accepted Answer

Increased rework if errors in overlapped activities propagate downstream

Answer

Increased project cost due to overtime pay

Answer

Reduced resource availability on critical activities

Answer

Extended baseline duration beyond contract requirements

Question 7

Schedule recovery plans are most commonly triggered when:

Accepted Answer

The Schedule Performance Index (SPI) falls below an acceptable threshold

Answer

Total float exceeds 10 days on all paths

Answer

Resources are over-allocated by more than 50%

Answer

The project achieves milestone completion ahead of schedule
