Cumulative S-curves:

You replied - Thanks Rafael - we don't have these report generators..... are they options in P6 or an external package ?

• These are options on other software, among them old P3 software, I expect similar options to be available in P6 as these reports have been required for decades.

If your software cannot generate with ease such S-Curves as it should you might try external packages sych as Project Tracker.  Based on what their brochure says I would expect Current and Baseline Early and Late S curves be available.

• Project Tracker S-Curve Software
•  

filter for what you want then selecy select view show on bottom then select activity usage profile

then right click on the lower right graph area and select activity usage profile options

from here you can select either costs or units to be diaplayed as well as the baseline and or the current schedule

This is how ancient P3 would give you the Early and Late Cumulative "S" Curves for current plus two target/baselines.

This is how Spider Project would give you the S Early and Late Curves for current plus two baselines named baseline and compared schedules.

I do not use P6 but it shall be as easy as 1,2,3, so easy, no big deal.

do you use store period performance ? if not you should 

As soon as there is progress and the DD is moved then for current updated schedule actual Early and actual Late S Curves will overlap to the left of DD giving you the impression it is a single line. Then after the current DD they will separate showing current plan early and late cumulative S Curves.  Try setting your diagram to show both Early and Late cumulative S Curves and nothing else.  

If you select to display remaining S Curves, only remaining values at DD will be considered and it will be 0 at DD.  It will not accumulate whatever is at the left of the DD.  Try setting your diagram to show both Early Remaining and Late Remaining cumulative S Curves and nothing else.

You can add to the diagram the original plan Early and Late S curves.

Now try showing all at the same time.

Good Luck

To obtain the required curve, Actual Values shall equate with Earned Values and the Remaining Values shall be the difference between At Completion and Actual Values.

Early Remaining or Late Remaining Curves shall originate from the End of the Actual Values at Data Date. The Curve shall be Continues until At Completion Values.

progress based on what dollars, manhours or units ? What is your measuing stick ?
