EVM Webinar : SPI near 1
EVM Webinar : SPI near 1
You are in the last month of your project, this project lasted for 24 months , you look at CPI and SPI and found CPI is .7 and SPI is .95 , does this mean that project was more or less on schedule but costed more than planned?
Re: EVM Webinar : SPI near 1
project was more or less on schedule; project is over-budget
For every dollar we spent - we got only 0.7$ value back so far. Money was spent inefficiently on the project
SPI = EV/PV (if PV was 100$; then EV = 95)
CPI = EV/AC
then AC ~ 135$
CV= EV - AC = 95 - 135 = -40$ (over budget)

Re: EVM Webinar : SPI near 1
The project has neither ever been on schedule nor been on budget throughout the course of 24 months
Let's assume that this project whose duration is 24 months has a planned value of 1 in each month.
At the end of 24 months the PV=24
Now we have CPI= 0.7 and SPI= 0.95
SPI=EV/PV
0.95= EV/24
EV= 0.95*24= 22.8
Now use this EV to calulate AC from the CPI formula- CPI= EV/AC
AC= 22.8/0.7= 32.57
Now CV and SV will be negative here for during the 24th month
If we quickly do these calculations for 12th month and 6th month, we continue to get negative CV and SV values. This shows that budget and time have always been a problem on this project.
Suggestions/Thoughts are welcome.
