Thank you.

Which one to use, if the CPI or SPI kept changing at random till now? Is BAC/CPI the most commonly used?

EAC = BAC / CPI
Use this when you have a trend on your project you expect to continue, and does not pose issue to the project.

EAC = AC + (BAC - EV)
Use this if you had a deviation on your project, but going forward you expect the project to be brought back in alignment with plan.

EAC = AC + ((BAC - EV) / (CPI x SPI))
Use this if schedule performance must be considered (e.g. if project is behind schedule).

I have seen the following equations for EAC

EAC = BAC / CPI

EAC = AC + (BAC - EV)

EAC = AC + ((BAC - EV) / (CPI x SPI))

Can you please clarify the criterion by which one of these can be used? Like, at which situation, should we use one particular formula from these?
