Final answer:
To find the earned value of a project with an SPI of 0.8 and a planned value of $125,000, multiply the SPI by the planned value, resulting in an earned value of $100,000.
Step-by-step explanation:
If the SPI (Schedule Performance Index) of your project is 0.8 and your planned value is $125,000, then to calculate the earned value (EV), you simply multiply the planned value by the SPI. Therefore, the earned value would be:
EV = SPI × PV = 0.8 × $125,000 = $100,000
This means you have earned $100,000 in value on your project based on the SPI provided.
