You are the program manager of the HNG Program. This program has a budget at completion of $2,345,900 and is expected to last two years. The program is currently 30 percent complete and you have spent

The correct answer is B. .86. The Schedule Performance Index (SPI) equals Earned Value divided by Planned Value, and yields 0.86 for this program, confirming it is behind schedule.

Program Schedule Management

Question

You are the program manager of the HNG Program. This program has a budget at completion of $2,345,900 and is expected to last two years. The program is currently 30 percent complete and you have spent $789,000. The program is supposed to be 35 percent complete but do to some delays you're slightly behind schedule. Based on this information, what is the schedule performance index (SPI) for this program?

Options

  • A$821,065
  • B.86
  • C1.05
  • D.89

Why each option

The Schedule Performance Index (SPI) equals Earned Value divided by Planned Value, and yields 0.86 for this program, confirming it is behind schedule.

A$821,065

$821,065 is the Planned Value (PV), which is an input to the SPI formula - it is a dollar amount, not a dimensionless performance index.

B.86Correct

EV = BAC x actual % complete = $2,345,900 x 0.30 = $703,770. PV = BAC x planned % complete = $2,345,900 x 0.35 = $821,065. SPI = EV / PV = $703,770 / $821,065 = 0.857, which rounds to 0.86. An SPI below 1.0 confirms the program is behind schedule, which is consistent with the stated delays in the scenario.

C1.05

1.05 would indicate the program is ahead of schedule (SPI greater than 1.0), which directly contradicts the stated schedule delays.

D.89

0.89 does not result from correctly applying EV and PV derived from the given BAC and percentage values, and is not supported by the data provided.
