Earn Value Management: cumulative values

fti · 06-07-2011 3:55pm #1

Hi everyone

I am working on my PMP certification and there's a point I still have trouble to understand.
I think I have pretty much understood what are EV, AC, PV, CPI, SPI and variances.

I don't think I could explain really what are cumulative values (CPV, CEV, CCPI, CSPI,...) are. For example a question states:
EV=670, AC=695 (not good, CPI < 1

) and CEV=675 ( in other words EV+5) and CAC=700 (again AC+5).

Where does that difference of 5 between AC/EV and CAC/CEV comes from?

Does it mean that we're considering two periods ?:
period# EV AC
1 5 5
2 670 695

Thanks for any advice on the question.

MMmm - I passed my PMP exam and don't remember this coming up at all! cumulative values - the questions on the exam are a little easier then this.
