A work package has earned value of $240,000 and planned value of $300,000. What is the SPI?
Correct Answer
C) 0.80
SPI is EV / PV = $240,000 / $300,000 = 0.80.
Why This Is the Correct Answer
SPI is EV / PV = $240,000 / $300,000 = 0.80.
Why the Other Options Are Wrong
Option A: 1.25
earned value spi, choice a: 1.25 equals $300,000 / $240,000. That divides those two listed numbers.
Option B: 0.60
earned value spi, choice b: 0.60 backs into 0.75 when divided by 240000 / 300000; the accepted setup gives 1 on that same base.
Option D: 1.08
earned value spi, choice d: 1.08 backs into 1.35 when divided by 240000 / 300000; the accepted setup gives 1 on that same base.
Memory Technique
Say the earned value SPI rule aloud as a chain; the chain ends at 0.80, not an intermediate stop.
Reference Hint
Open Construction Jobsite Management, 5th Ed. (2024); use by topic index - duration / float / baseline / updating / variance to confirm that SPI is EV / PV = $240,000 / $300,000 = 0.80.
