This is question no.63 in Lehmann

Question : You are performing earned value technique on your project.After budget approval, an additional and unexpected cost item has been identified, which made the project more expensive some weeks ago. The item has meanwhile been paid by the project team, and it is expected that for the remaining duration of the project, costs will be as budgeted.

In this case, which is the best formula to calculate EaC (Estimate at Completion)?

Choice :

A.EaC = BaC - CV
B.EaC = BaC / CPI
D.You can not compute the EaC

Guys need you to clarify me .. and Give me suggestion( in layman technique) that how shall i identify the EAC and ETC related formulas.

Variances are atypical, so you should use formula:

EAC = AC + BAC - EV

you can also write this formula in following way:

EAC = BAC - (EV - AC)

Cost Variance formula is CV = EV - AC

Therefore

EAC = BAC - CV

Answe A is the right one

Good luck.
