Explanation

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. You can find the planned value by multiplying where Billy should be in the project, 100 percent, by the project's budget. In this instance the planned value is $655,000 because she is to be 100 percent complete. Answer option B is incorrect. The SPI simply reports a value not an explanation. Answer option A is incorrect. 1.23 is the cost performance index for the project. Answer option D is incorrect. $524,000 is the earned value for the project.
