CST Schedule Variance & Delay Analysis 2

Question 1

A project reports SV = -$15,000 and SPI = 0.82. What do these metrics collectively indicate?

Accepted Answer

The project is behind schedule and completing less work than planned per dollar spent

Answer

A negative SV and SPI below 1.0 both confirm the project is behind schedule, completing only 82 cents of planned work per dollar of time elapsed.

Question 2

Which delay analysis technique overlays the as-planned schedule against the as-built schedule to identify where delays originated?

Accepted Answer

As-Planned vs. As-Built comparison

Answer

The As-Planned vs. As-Built comparison graphically overlays both schedules to identify divergence points and delay sources.

Question 3

During a delay claim, the opposing party argues that your critical path delay was concurrent with their excusable delay. The most likely result is:

Accepted Answer

Time extension may be granted but no additional compensation for the overlapping period

Answer

Concurrent delays typically result in a time extension for the overlapping period, but additional costs are generally not awarded to either party during that window.

Question 4

A schedule shows Total Float = 0 and Free Float = 0 for Activity X. If Activity X is delayed by 5 days, what is the most likely impact?

Accepted Answer

The project finish date is delayed by 5 days

Answer

Zero total float means the activity is on the critical path, so any delay directly extends the project finish date by the same duration.

Question 5

The Earned Schedule (ES) method improves upon traditional EVM schedule metrics by:

Accepted Answer

Converting SV from dollars to days, providing a time-based schedule variance

Answer

Earned Schedule converts the schedule variance from a cost-unit measure to actual time units (days/weeks), making schedule slippage directly interpretable.
