TOPIC: Earned Value and Estimate to Complete in Months.

Ref. to this article (which was referenced in one of the emails from PM PrepCast):

www.projectsmart.co.uk/earned-value-management-explained.html

I learned that:

SP = EV - PV

will give the unit result in Months, but I am not convinced. See the Problem and solution mentioned in the article.

Also, I learned that to calculate the Estimate Months to Completes I use this formula:

Estimate Months to Complete = (BAC - EV) / SPI

Or,

Total Months taking the variance into consideration

New Estimate Total in Months = Original Planned Months / SPI

There is no much reference to such formula anywhere in the net nor in the Formula Study Guide.

I hope my understanding is correct.

In case you have any comment, I appreciate you feedback.
