Gents,
Could you kindly provide me an idea about S Curve Vs Project schedule Summary.

The S-Curve is a graphic display of cumulative costs, labor hours, or other quantities, plotted against time (source: the Project Management Dictionary http://www.pmhut.com/pmo-and-project-management-dictionary ), the project schedule summary, afaik, is not usually graphical, and may contain more data.

Congratulations. You are entering the world of earned value analysis: the only project management tool that can status the project triumvirate of schedule, cost and scope in real time.

An EVA project's graphical representation usually follows an S curve: slow start, ramp up, ramp down.

People get hung up on the whole 'S curve' thing and then get upsett when your actual costing against their SOW doesn't fit the curve.

Months, maybe years of misary with BAE Systems on that one, if the work/schedule required by the SOW isn't "S" shaped then nor will our billing be.

The curve should be according to your time phased effort or cost. For a long enough and complicated enough program, the shape could be quite complex.

I'm not sure why your customer would have a different curve that you, since they can only generate that curve from the submitted cost proposal, which should match your execution curve.

They 'wanted' a typical S curve. However, with the SOW they gave us, and the way they wanted invoices against deliverables, and when the listed 'deliverables' occured in the project time-line it wasn't an S curve.

Their finance guy just would not let it go. He couldn't accept that their own SOW didn't support an S curve. Did nothing to improve my opinion of bean counters.

Hey, watch that! Our GM is/was a bean counter, and is one of the 3 best GMs I've had in 31 yrs of working.

While it's PC to dump on bean counters, there are similar types in engineering...

There's an exception to every rule right IRstuff

.

I too have met a few obtuse engineers, and didn't mean to imply otherwise. I haven't yet met a Bean counter that I have warm fuzzies for, at least not one I've worked closely enought with to know the difference.
