S-Curve
Graphic display of cumulative costs, labor hours, percentage or work, or other quantities, plotted against time. Used to depict planned value, earned value, and actual cost of project work. The name derives form the S-like shape of the curve (flatter at the beginning and end, steeper in the middle) produced on a project that starts slowly, accelerates, and then tails off. Also a term used to express the cumulative likelihood distribution that is a result of a simulation, a tool of quantitative risk analysis.
