Beyond SPI & CPI
OK, so you routinely calculate and report SPI and CPI for your projects, but what other information does the EVM chart tell us? Let’s take a detailed look at the information provided by our Earned Value calculations and chart, what the chart shows (and what it doesn’t). Are you really measuring the right things? Are there elements of your project schedule or cost/spending plan that skew the data?

How much is it really going to cost?
CV = EV – AC; CPI = EV/AC CV = -$75,000; CPI = 0.98
EAC = AC+(BAC-EV)
$6,825,000

Can we recover?
TCPI = 1.03 Is that good or bad?
Be careful – if you use the EAC: TCPI = (BAC-EV)/(EAC-AC) TCPI = 1.00 You’ve changed the target!
