PMI-SP Exam - Topic 9 Question 2 Discussion

Actual exam question for PMI's PMI-SP exam

Question #: 2
Topic #: 9

You are the project manager of the NHA Project. This project is expected to last one year with quarterly milestones throughout the year. Your project is supposed to be at the third milestone today but you're likely only 60 percent complete. Your project has a BAC of $745,000 and you've spent $440,000 of the budget-to-date. What is your schedule performance index for this project?

A80

B1.02

C102

D0.80

Show Suggested Answer

Suggested Answer: D

The schedule performance index can be found by dividing the earned value by the planned value. In this project, it's $447,000 divided by the $558,750 for a value of 0.80. 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 A is incorrect. "80" is not the same value as ".80". Answer option B is incorrect. 1.02 is the cost performance index. Answer option C is incorrect. 102 is not a valid calculation for this question.

Totally agree, looks like we're behind schedule.

Wait, is it really only 60% done? That's rough.

I think it's definitely lower than 1.

The SPI is calculated as EV/PV.

I feel like I might be overthinking this. If we're only 60% complete, does that mean the SPI is less than 1? I need to double-check my calculations.

I think the formula is SPI = EV / PV, but I’m confused about how to find the earned value (EV) and planned value (PV) in this scenario.

I remember something about calculating the SPI using EV and PV, but I'm not entirely sure how to apply it here.

I practiced a similar question where we had to determine the SPI, and I think I got it right by using the budget and completion percentage.

I'm pretty confident the answer is D. C2C makes the most sense since eBay is enabling transactions between regular consumers, not businesses.

Hmm, this looks like a tricky one. I'll need to think through the requirements carefully to determine the right objects to create.

Okay, let me see. I remember MoV is all about maximizing value, so I'm guessing it wouldn't be useful when the asset is already decommissioned or in the operational phase. I'll go with B or C.
