[Verse 1]
When your project's underway and you need to track the flow
Earned Value Management helps you see just where you go
Planned Value is your baseline, what you thought you'd spend today
Earned Value shows the work done, Actual Cost is what you pay
[Chorus]
Schedule Variance, EV minus PV
Cost Variance, EV minus AC
SPI divides EV by PV
CPI divides EV by AC
These are the keys to EVM success
Measuring performance, nothing less
[Verse 2]
When your SPI is greater than one, you're ahead of time
When your CPI exceeds one, your budget's looking fine
But if these indices fall below, you've got some work to do
Schedule or cost performance needs attention from your crew
[Chorus]
Schedule Variance, EV minus PV
Cost Variance, EV minus AC
SPI divides EV by PV
CPI divides EV by AC
These are the keys to EVM success
Measuring performance, nothing less
[Bridge]
Estimate at Completion has three ways to calculate
BAC divided by CPI when performance stays on rate
AC plus BAC minus EV when it's atypical
AC plus that same difference divided by both indices critical
[Verse 3]
ETC is your Estimate to Complete what remains
EAC minus AC will ease your calculation pains
VAC shows Variance at Completion, BAC minus your EAC
TCPI tells you the performance index that you need to see
[Chorus]
Schedule Variance, EV minus PV
Cost Variance, EV minus AC
SPI divides EV by PV
CPI divides EV by AC
These are the keys to EVM success
Measuring performance, nothing less
[Outro]
TCPI equals BAC minus EV
Over BAC minus AC, you see
With these formulas in your mind
Project success you're sure to find
