Cost Formula Difference
Submitted by mickcalcara on Tue, 05/18/2010 - 17:45
Hi, I notice Estimate at Completion formula difference.
In Rita Mulcahy book ( pg 242 ) a variation of EAC is listed as:
‘AC+[(BAC-EV)/(Cumulative CPI + Cumulative SPI)]
In PMBOK (Pg. 185 ) this is listed as:
‘AC+[(BAC-EV)/(Cumulative CPI * Cumulative SPI)]
I assume the PMBOK formula is the most accurate. Can someone verify this?
Thanks

AC+[(BAC-EV)/(Cumulative CPI
AC+[(BAC-EV)/(Cumulative CPI * Cumulative SPI)] is the correct formula
