Hi All,


Q: You know that BAC = 375, PV = 300, AC = 200, and cumulative EV = 250. Variances that have occurred on the project to date are not expected to continue. What is the ETC?


A.    75


B.    50


C.    125



 


 



        D.    150


Kim has given : The correct formula for ETC for this question is as follows: BAC - cumulative EV.


I have ever seen only one formula for ETC = EAC – AC.  Please clarify.

Hi Mani,


ETC = EAC - AC is correct. What do you substitue for EAC. ?


EAC =  BAC/CPI if the same performance continues. But questions mentions same performance is not expected to continue. So you should consider atypical formula for EAC calculation


EAC = AC+ BAC-EV. Substitue this for EAC in your ETC formula


Therefore ETC = (AC +BAC - EV) - AC. That means ETC =  BAC - EV.


Hope this helps.
