You are the project manager of the HQQ Project. Your project is running late by ten percent of
where you should be at this time. Management is concerned and they’d like to know what is your
schedule performance index. Considering that the project has a BAC of $567,899, you are thirty
percent complete, and you have spent $179,450, what is the SPI for this project?

A.
$227,140

B.
0.75

C.
0.95

D.
-$56,789

Explanation:
The schedule performance index is found by dividing the earned value by the planned value. In
this instance, the planned value is ten percent more than where the project is forty percent of the
budget at completion. Schedule performance index (SPI) is the measure of schedule efficiency on
a project. It is used in trend analysis to predict future performance. SPI is the ratio of earned value
to planned value. The SPI is calculated based on the following formula: SPI = Earned Value (EV) /
Planned Value (PV) If the SPI value is greater than 1, it indicates better than expected
performance, whereas if the value is less than 1, it shows poor performance. The SPI value of 1
indicates that the project is right on target.
Answer option C is incorrect. 0.95 is the project’s cost performance index.
Answer options A and D are incorrect. An index is a decimal value.
