EAC = BAC/CPI vs ac + bac - ev

Postby staneja Mon Apr 07, 2014 5:32 pm

EAC = BAC/CPI ..to be used when variance are seen in the work and will continue provided that CPI remains same

ac + bac - ev to be used when variance is seen only one time and then project continues at the budgeted rate.


Which formula do we use if variance type x is seen then variance type y is seen.I mean to say the variances are not following any trend in the project but they continue.

Please do guide me

Thanks

I would recommend to use the formula - EAC = AC + Bottom-up ETC

Its better to re-estimate if PM can foresee so much of variances with the planned values.

What about EAC =AC+[(BAC-EV)/(CPI*SPI)] ?
Is it possible to use this formula in this case ?

Ranjit,

To use formula EAC =AC+[(BAC-EV)/(CPI*SPI)], we need to see the following three points:

point #1 typical variation in cost so CPI is required
Point#2 variations in schedule
Point #3 firm date ask by sponsor

If the scenario fulfills all 3 points, then only we can use above said formula.

Let me know if u have any followup query :)

We can add additional resources to the schedule with the amount of worth of VAC (Eac-BAC).
Then the project will complete on time.
