Q No.80 of Mock Test ETC

Postby JOYDIP DEY Sun Apr 23, 2017 6:19 pm

Dear All,

To me this Question and its answer given in the Izenbridge. com is not clear. I have picked up this Q from Mock Test(Q No.80).
80. Question
You are managing a project which is estimated to cost $ 300,000 with a timeline of 10 months. Due to some reasons schedule was slightly delayed and the net result was that there was some additional cost in the project. At the end of the third month, you review the project and find that the project is 30% complete and Actual Costs are $ 50,000. The Estimate to complete (ETC) for the project would now be:
• $200,000
• $210,000
• $230,000
• $220,000

Answer – B
Now my Question is why i should not calculate EAC in this case and then calculate ETC. In that case answer becomes different than the answer given above. Can anybody explain me the same. Looking forward Joydip

I am not an expert but I think that ETC is Work remaining (i.e Total work minus work completed) . Total work is BAC( Budget at Completion) minus Work completed (i.e Earned Value) . The cost increase has nothing to do with ETC and i think its just to misguide.
Therefore :

Work remaining=ETC=BAC-EV
Work remaining=ETC= 300000-(0.30 *300000)=210,000

If we had known by how much amount cost has increased then may be we would have found EAC since BAC would be changed . But yes question takes us there and then leaves by just asking us amount remaining work which Estimate to Complete.

This is just my understanding. Experts please correct if wrong.

Project is slightly deviated but rest of the work will be in planned way as not directly mentioned.
ETC = EAC -AC = BAC + AC -EV -AC = BAC -EV =300- .3 x 300000 =210,000
Best Regards.
