You are halfway through your project and your sponsor would like to know how much the project is expected to cost when it is completed. What earned value metric should you use?

A. CV
B. AC
C. EAC
D. ETC

Answer: C. EAC
EAC (Estimate at Completion) tells you that the project is expected to cost x dollars. This is derived from how much you thought it would cost from the beginning (BAC) and what the rate of spending is (CPI).

As the project manager with a time conscience sponsor, you have been monitoring earned value throughout the year long project. At the halfway point, you report that the SPI is 0.8. This means that the project is:

A. Ahead of schedule
B. Under budget
C. Behind schedule
D. Over budget

Answer: C. Behind schedule
The Schedule Performance Index (SPI) determines how much ahead or behind schedule you are. An SPI of 1.0 means you are on target. Therefore, an SPI of 1.5 means that you are progressing at 150% of the baseline, which is a good thing. Conversely, an SPI of 0.8 represents only moving at 80% of the baseline, not so good. In short, over 1.0 is good, under 1.0 is bad.

At your upcoming status meeting with your project sponsor, rather than just using a table, you want to graphically show earned value. Which of the following charts will you use?

A. Trend analysis
B. Control chart
C. S-curve
D. Pareto diagram

Answer: C. S-curve
An S-curve graph typically displays earned value (EV), planned value (PV) and actual cost (AC). PV is charted first and will look like an S. As time progresses, the EV and AC will extend allowing you to compare them against the PV.

If a project has a Cost Variance (CV) of 1000 and a Schedule Variance (SV) of -1000, what does it mean?

A. The project is under budget and behind schedule.
B. The project is over budget and ahead of schedule.
C. It is impossible to have a negative SV.
D. The Overall Variance (OV) is 0.

Answer: A. The project is under budget and behind schedule.
For both Cost Variance (CV) and Schedule Variance (SV), if the number is positive, then it is good. Conversely, if the number is negative, then it is bad. So CV of 1000 is good (under budget), while SV of -1000 is bad (behind schedule). There is no such thing as Overall Variance (OV).
