Hi,

 

Please can can anybody provide me with the actual calculations IFS uses behind the Project Spread Profile > S-curve Definition? See below screenshot.

 

Thanks in advance.

Stephen

 

Stephen,

The s-curve uses the Gradient field to determine the steepness of the S-Curve, and in the Mid-Point field, the point at which half of the cost should have been distributed.

So in your example 50% of the costs are used at the 6th interval.

Regards,

Antony


Thanks for your reply Antony.

 

Please could you provide the actual formula that is used in the S-curve?

 

There are several potential ways of calculating an S-curve and our client would like to know what we have in IFS so they can compare it against their current formula.

 

Thanks

Stephen


Stephen,

I haven’t go the actual formula, but attached is document which details it a bit more so hope that it helps.

Regards,

Antony
