CV (Cost Variance) ✔Correct Answer-EV - AC (earned value - actual cost)
SV (Schedule Variance) ✔Correct Answer-EV - PV (earned value - planned value)
CPI (Cost Performance Index) ✔Correct Answer-EV / AC (earned value divided by actual cost)
EAC (Estimate at Completion) ✔Correct Answer-BAC / CPI (budget at completion divided by cost
performance index)
ETC (Estimate to Complete) ✔Correct Answer-EAC - AC (Estimate at Completion - Actual Cost)
VAC (Variance at Completion) ✔Correct Answer-BAC - EAC (Budget at Completion - Estimate at
Completion)
PERT ✔Correct Answer-(P + 4M + O) / 6
Standard Deviation of Activity ✔Correct Answer-(P - O) / 6
Variance of an Activity ✔Correct Answer- [ (P - O) / 6] squared (standard deviation squared)
Total float ✔Correct Answer-LS - ES or LF - EF
EAC (Estimate at Completion -2) ✔Correct Answer-AC + ETC (actual cost plus estimate to complete)
EAC (Estimate at Complete - typical variance) ✔Correct Answer-AC + (BAC - EV) (actual cost plus the
total of budget at completion minus earned value)
EAC (Estimate at Completion 4) ✔Correct Answer-AC +((BAC-EV)/CPI)
Cumulative CPI ✔Correct Answer-EV (cume) - AC (cume)
Present Value (PV) ✔Correct Answer-FV / (1 + r) to the n-th power
Communication Channels ✔Correct Answer-[N * (N-1) ] / 2
