What is the S-Curve, and how do calculate the work progress..

Expert Project Management - The Mysterious S-curve

OOPS - Seems like the author forgot about early and late S-curves, it is an abysmal omission!

On the other hand the following author did not forgot late curves for Current Schedule while for Baseline he forgot also Baselines have late S curves.

Hi all,

I'w working on a shutdown schedule and want to generate S curve by WBS level. I created a layout for each WBS level and generate my curve. But the problem here is : I have 16 WBS levels and it will cost me a lot of time to print one by one.

Is there a solution to print all the curves in one shot ? one file ?

Thanks for your feedback.

Morne Beeslaar warning on productivity rates being at best a guess cannot be overlooked.  No way can you overlook the reliability of the source data you uses when creating the S-curves.

·       You need to track production rates.

·       Easier to track if using Unit Costing capable financial/accounting software.  The mere tracking of budgeted amounts is not good enough.

·       https://www.foundationsoft.com/unit-cost-production-reporting/

·       Easier to model if using scheduling software that correctly model production rates in easy to understand implementation instead of missing this important value .

There are a variety of S-curves that are applicable to project management applications, including: Man Hours versus Time S-curve, Costs versus Time S-curve, Baseline S-curve, Actual S-curve, Target S-curve, Value and Percentage S-curves.

·       Some important S-curves any scheduler shall understand are missing:

·       The Probabilities of Success curve.

·       http://www.goodplan.ca/2011/02/s-curve-of-success.html

·       EVM S-curves.

Also is missing the misconceptions and pitfalls of some S-curves that shall be included in any reference to S-curves for it to be complete.

·       Earned Value Management as a tool for Project Control

·       The Great Divorce: Cost Loaded Schedule Updating

Good information and theoretically sound.

Problem in South Africa is that contractors are notoriously poor at just producing a level 3 schedule never mind getting cost or resource loading done to produce manhour schedules. Productivity rates are at best a guess.

Thanks for a great article though.

Hi,

where I can get pictures , that would be easier to understand

It is a good article, but unfortunately, the picture in it can not display normally.
