The correct answer is C. 0.92. The Schedule Performance Index (SPI) equals Earned Value divided by Planned Value, which calculates to approximately 0.92 for this project.
Question
You are the project manager of the NNH Project. In this project you have created a contingency response that the schedule performance index should be less than 0.93. The NHH Project has a budget at completion of $945,000 and is 45 percent complete though the project should be 49 percent complete. The project has spent $455,897 to reach the 45 percent complete milestone. What is the project's schedule performance index?

Why each option
The Schedule Performance Index (SPI) equals Earned Value divided by Planned Value, which calculates to approximately 0.92 for this project.
-$37,800 appears to be an arithmetic difference between two monetary values and is not a valid SPI, which is always expressed as a dimensionless ratio.
0.93 is the contingency threshold established in the project risk response plan, not the SPI calculated from the actual earned and planned values.
EV = 45% x $945,000 = $425,250 and PV = 49% x $945,000 = $463,050. SPI = EV / PV = $425,250 / $463,050 = 0.9183, which rounds to 0.92. This value is below 1.0, confirming the project is behind schedule, and it also falls below the contingency threshold of 0.93 defined in the project's risk response plan.
1.06 would indicate the project is ahead of schedule, which contradicts the data showing actual progress (45%) is behind planned progress (49%).
