# TOPIC: Question: "Variance will probably remain same" vs "Variance will not occur again" ETC/EAC

## Question: "Variance will probably remain same" vs "Variance will not occur again" ETC/EAC 7 years 9 months ago #8800

 Kelly Coughlin Topic Author Offline Junior Boarder Posts: 24 Karma: 1 Thank you received: 6 Ok, I am quite confused by the wording for EAC & ETC formulas, particularly: EAC = BAC / CPI Assumption: use formula if current variances will probably remain the same through the end of the project. vs EAC = AC + (BAC - EV) Assumption: use formula if current variances will probably not occur again through the end of the project, which means the original budget is more reliable Doesn't "variance will remain the same" equate to "Variance will not occur again"? How do you know which formula to use if the wording is not precise in the question? Your e-mail address will never be displayed on the site. Check this box to be notified of replies to this topic.

 Cornelius Fichtner Away Administrator President, OSP International LLC Posts: 1983 Karma: 120 Thank you received: 609 Kelly, Here is the explanation: "variances will probably remain the same" means that we currently have a variance of X and that this variance will remain until the end of the project. "variances will probably not occur again" means that we currently have a variance of X but this variance will go away and the project will be back on track until the end. Note that it says "variances will probably NOT occur again". If the exam question does not use the exact wording then simply ask yourself this: Will the variance stay the same or will it got away? The answer to that question will tell you which formula to you. Until Next Time, Cornelius Fichtner, PMP, CSM President, OSP International LLC Your e-mail address will never be displayed on the site.
