how to make a forecast curve?

Hi,

How can I adjust my forecast curve. if you have any exmaple to please provide 

Thanks

hi jeff reyes,



You know,arnold and anoon are right with regards to that reporting in comparing the current schedule vs planned scheduled which includes the earned cost and the manhours and the real billing...i guess we have the same procedure in reporting the forecasts im also new with this works...but mine project activities are more on electro-mechanical for 4 star hotel with a 34 floors.



with this,its a big help when we help each other...thank you and more power guys...

i believe another problem you’ll be having is during the reporting, how to explain it to the audience, remember not all of them are planners, just make sure you got all the back-ups (and you can handle stress).



no, i’m somewhere around, been there also (ingat lang).

Jeff,



Try to check and compare your Target (Planned - Original Schedule), which has the original forecast (early curve as you said), but remember you also have your late curve on the same schedule which can originally be used as forecast as well.



Now you have your Current/Updated Schedule, (Arnold is right), forget about all the original forecasts that you had derived from your Baseline or Target Plan (just keep the records). Your new forecasts now are to be reckoned from your Current/Updated Schedule, which can either be late or early.



From there, you can now establish the comparisons (Planned vs.Actual Forecasts), just make sure you labeled your curves correctly (you can do this in excel).



By the way you guys have plenty of time PP..ing while working?

Hello Jeff,



Yap, I’ve been working for 7 years in Saudi Arabia before I transfer to Abu-Dhabi. I worked for SAUDI ARAMCO Project for 5 years & 2 years in RC Jubail Project. If you don’t mind, can you send me your Files both Excel & Primavera, I can help you on this. I know the format of RC Project that they are using. If it is okey for you, I know you’re Filipino, me too.



My email is p3-fer@sixco.ae

Yes, you are right Anoon. I’m just trying to explain to Jeff why his forecast went under the early curve.

Arnold,



I agree with what you said (but not only in P6), Forecast can be early and late as well. Forecast of the remaining works from your current/updated schedule (which has early and late curves also).

Hi Jeff,



In your Progress Curve there should be Four Curves:



1. Early Curve

2. Actual Curve

3. Late Curve

4. Forecast Curve



These Four curves above came from your Primavera Files. The Early Curve is your Target/Baseline Curve. Actual is the current/update schedule. Late Curve is your late Planned & Forecast is your Planned for the next update of remaining activities.



Now, to get your forecast it depends on your lookahead schedule. In P6 this is your Remaining Early Curve based on current schedule & not based in your baseline schedule.



Now, if you are using P3x you can export this data from P3 to excel by using Tools --> Tabular Reports --> Resource --> Tabular, depending in your resources.



If you have your forecast curve went under your early curve, I assumed that is not forecast, that is late curve. However, if that value is correct then you might have to double check with your CM.



Forecast curve always starts from your data date because this is the starting point for schedule calculation of remaining activities.



Jeff, are you working with Jubail Royal Commission Project & the PM Consultant is BECHTEL?



HTH.

Hi Jeff,



In addition to what Mr. Anoon’s post, you can export all the datas & values from your P3, P5 or P6 to Excel. Based on that Planned Values (Early or Late) you have consider in your schedule. By adding these Planned Values you can now produce & create the forecast curve to your Progress Report.

a forecast curve is a planned curve, create your curve using planned data.
