EVM Certification EVM Certification Schedule Management & Performance

Question 1

What does the Schedule Variance (SV) measure in Earned Value Management?

Accepted Answer

The difference between Earned Value and Planned Value in cost terms

Answer

SV = EV – PV and expresses schedule performance in dollar terms, with positive values indicating ahead of schedule.

Question 2

A project has an SPI of 1.15. What does this mean?

Accepted Answer

The project is ahead of schedule, earning $1.15 of planned value for every $1.00 scheduled

Answer

SPI > 1.0 indicates the project is ahead of schedule, accomplishing more work than was planned for this period.

Question 3

Which EVM metric is calculated as the ratio of Earned Value to Planned Value?

Accepted Answer

Schedule Performance Index (SPI)

Answer

SPI = EV / PV and measures schedule efficiency by comparing the value of work done to the value planned.

Question 4

One known limitation of the traditional SPI metric is that:

Accepted Answer

SPI converges to 1.0 at project end regardless of actual schedule performance

Answer

Because EV always equals BAC at project completion, SPI mathematically approaches 1.0 at the end, masking late-project delays.

Question 5

What is Earned Schedule (ES) designed to address compared to traditional SV and SPI?

Accepted Answer

It measures schedule performance in time units rather than cost units to avoid the convergence problem

Answer

Earned Schedule converts EV-based schedule metrics into time units, providing more accurate indicators late in the project.
