Earned Value Management (EVM) Example – Predicting Cost/Finish Date
By Umesh Dwivedi
The best way to understand an EVM example is to solve it.
A project is budgeted for $10M and scheduled for 10 months. It is assumed that the total budget will be spent evenly every month for 10 months. After 2 months the Project Manager finds that only 5% work was finished and a total of $1M was spent. What is the total cost of this project and how much time will it take to be finished?
PV = $2M
EV = $10M * 0.05 = $0.5M
AV = $1M
CV = EV-AC = 0.5-1 = -0.5M
CV% = 100 * (CV/EV) = 100*(-0.5/0.5) = -100% overrun
SV = EV-PV = 0.5-2 = -1.5 M
SV% = 100 * (SV/PV) = 100*(-1.5/2) = -75% behind
CPI = EV/AC = 0.5/1 = 0.5
SPI = EV/PV = 0.5/2 = 0.25
EAC = BAC/CPI = 10/0.5 = $20M
ETC = (BAC-EV) / CPI = (10-0.5)/0.5 = $19 M
Time to complete = (10-0.5)/0.25 = 38 Months
This project will take total of $20M (19+1) and 40 (38+2) months to complete.
