EVM Formulas

1. EV = PV to date * RP
2. CV = EV - AC
3. SV = EV - PV
4. CPI = EV/AC
5. SPI = EV/PV
6. EAC = BAC/CPI
7. ETC= OTE/SPI

EV - Earned Value

PV - Planned Value

RP - Rate of Performance

CV- Cost Variance

AC- Actual cost

SV- Schedule Variance

CPI- Cost Performance Index

SPI- Schedule Performance Index

EAC- Estimate at Completion

BAC-Budget at Completion

ETC-Estimated Time to Complete

OTE-Original Time Estimate

Analyzing

Important factors in project are cost and time

• CV represents the cost performance
• SV represents the time performance
• If they are positive, they are ahead of schedule/under budget if negative they are behind schedule/ over budget
• CPI represents the cost performance as an index/performance. It verifies the CV
• SPI represents the time performance as an index/performance. It verifies the SV
• Over 100% is good ( they are ahead of schedule/under budget ) 100% is neutral and below 100% is bad (behind schedule/ over budget)
• If EAC is higher than BAC then the project is performing worse than planned because the new estimate to complete the project is x more than planned.
• You get OTE from the question, where they mention how long the project was intended to take
• If ETC is higher than OTE then the project is performing worse than planned because the project is projected to take x months longer than planned.

GOOOOOOOOOOOOOOOD LUCK!!
