PMP Exam: Earned Value Management - Part 3, Forecasting Completion

[TheJimbaHut]

Thanks, but I think this video was a bit too much. Too many acrynoms and more examples required. Other than that, excellent video series.

[2106harish]

Excellent three videos! Best I have seen on the subject. You explain v well and your voice is inviting...to keep watching the video. I'm an instructor and will use these videos in my training programme tomorrow! Thanks again.

Best regards,

thanks a alot

Hi SirGanttalot,

i am a little confused by both the PMBOK & your Scenario 2 given in this video.

The explanation in PMBOK for bottom-up ETC is it is a manual process performed by PM and project team. So it isn't a formula as such. It then decides to give a formula in addition (although does not recommend to use this method), which is clear to me. Equation: EAC = AC + bottom-up ETC

Your scenario 2 states Equation: EAC = AC + new ETC, seems to be the same, but isn't explained well. Is it?

[jasonvincent027]

any chance you could explain cumulative please. You lost me there.

[SirGanttalot]

It means the total figures from the start of the project until now. So the Cumulative CPI would be the Cumulative Earned Value so far (the budgeted cost of all the work that has been done so far) divided by Cumulative Actual Cost (all the money actually spent so far). CPI(cum) = EV(cum) / AC(cum). It is important to use these cumulative numbers when you do FORECASTING, because your projection forward is going to be more accurate if you use the biggest historical sample possible.

I am following you with Project 2003. What Project is your videos based on? Project 2003 does not seem to be able to give you the 'S' curve shown in your video. Which Project, if any will give you a baseline S curve?

[stefanicai]

First 2 videos in the series were absolutely great. This one was just good as there were no actual examples of calculating based on actual data. Would have been great to see such as well.

Anyway, great work, thanks!

FYI.i just learned what is earned value management in my Bachelor programe.. really confused me & i never know whats it all about. pls help me more on this. thanks. regards.steward Pelok...from Malaysia.

Outstanding, I love your series on PMP! Well explained, informative and easy to understand and learn.

[SirGanttalot]

Many thanks for the fedback. I'm very pleased to know the videos are helpful. Best of luck with your studies.

[Ikepike66]

Vid 1 and 2 were great however vid 3 just chalked all the formulas on the board w/out explaining more how they help. Also real world calculations as you did in 1 and 2 would solidify the content. Maybe a Vid 4 explaining more BAC, TCPI, EAC and vid 5 with could run through calculations... Love your help on 1 and 2

[tmjromao]

Thank you. Very useful

[ramsrambo]

Thank you Great videos

[srini15574]

Thanks for the video...

According to the PMBOK4, EAC in Scenario3 is AC+ [(BAC-EV)/CPIxSPI)].

Is there a reason why you omitted the product of CPI and SPI in your video?

Just want to know why it is not used, or how it can be used.

cheers

[SirGanttalot]

Hello Srini. The various versions of the PMBOK over the years have always just shown a selection of all the possible formulas that are actually used by EV practitioners in the real world. That formula you mentioned is perfectly valid, and for the Exam I would recommend that you learn it, as the PMBOK mentions it. This particular formula is used in circumstances where there has been a LOT of variability in performance, and you need to take account of both schedule and cost performance so far.

[srini15574]

Perfect!! Thanks for the explanation and taking time out to answer this. Its been a great help in me understanding these formulae.

[keeno514]

no comments, well done videos, you are an expert of communication, you make it easy, thank you

[dshahpatel]

Thanks You Sir Ganttalot, videos have been really helpful.

[SirGanttalot]

You are welcome. I'm glad they have been of use to you.

[Nolanobombarlo]

Thanks so much for posting these, they are very helpful.

Can I just ask though:

How do you 'project forward your earned value or actual costs'?

Is there a way of accurately forecasting this curve at specific points in the future or is it a case of finding the EAC and then roughly drawing in an S type curve which links up to it?

Many thanks in advance

[SirGanttalot]

The simplest thing to to is take the PV at the point you want to forecast for, and use that value in place of BAC in the various formulas. If you think it through, PV of the entire project is the same as BAC, so PV at a particular point is like the "Budget At" that same point. Hope this helps.

[Nolanobombarlo]

OK, brilliant, i'll try it out, thanks again for your help and very useful information

[spectator2000]

Thanks sir .. You are awesome.

[Seek284]

Your latest posting is a great boom to me as I a getting ready to take my PMP exam.

Thanks again!
