With the PMP exam, I practiced making a brain dump several times, so that the first thing I did when I sat down to take the exam was to brain dump my formula on to a sheet of paper. This way, I could quickly reference the formula with ease. I followed the same pattern for the Risk Management Exam.
Risk = Probability * Impact
Probability = Chance / Likelihood
Mean = Average
Std Dev = SqRoot(Sum of data – Mean / No)sqd
Earned Value Management = x% change of y profit eg: 0.35 * 1000 = EVM
3 point estimate = (Best + 4 Likely + Worst) / 6
CV = Cost Variance = EV - AC
SV = Schedule Variance = EV - PV
CPI = Cost Performance Ind = EV / AC .... >1 spending less <1 overspend
SPI – Schedule Performance Ind = EV / PV .... >1 good <1 bad
EAC = Estimate at Completion = BAC / CPI
Note: There are three calculations for this - But this is the simple one.
ETC = Estimate to Completion = EAC - AC
BAC = Budget at Completion
Paerto = 80 /20 -> 80% occurrences from 20% of causes
These are the only formula I required for the Risk Management Exam.
