THE S-CURVE Introduction The first time most project managers become aware of the existence of S Curves is when they are requested by the client or senior management to include one in their next progress report. The following explains what the mysterious S Curve is‚ why it is an important project management tool‚ and how to generate one. What is a S Curve? A S Curve is defined as "a display of cumulative costs‚ labour hours or other quantities plotted against time. The name derives from

The Laffer curve‚ named after the economist Arthur Laffer‚ is a curve that demonstrates the trade-off between tax-rates and tax-revenues (Wanniski 1978). It is used to illustrate the concept of taxable income elasticity‚ the idea that a government can maximise the revenue by setting the tax rates at an optimum point. This curve can be traced back as far as 1844 to a French economist Jules Dupit who in 1844 found similar effects as Laffer did (Laffer 2004). Dupit also saw tax revenues rising from

Learning curve in psychology and economics The first person to describe the learning curve was Hermann Ebbinghaus in 1885. He found that the time required to memorize a nonsense word increased sharply as the number of syllables increased.[1] Psychologist‚ Arthur Bills gave a more detailed description of learning curves in 1934. He also discussed the properties of different types of learning curves‚ such as negative acceleration‚ positive acceleration‚ plateaus‚ and ogive curves.[2] In 1936‚ Theodore

Learning Curve Primer The concept of a Learning Curve is motivated by the observation (in many diverse production environments) that‚ each time the cumulative production doubles‚ the hours required to produce the most recent unit decreases by approximately the same percentage. For example‚ for an 80% learning curve: If cumulative production doubles from 50 to 100‚ then the hours required to produce the 100th unit is 80% of that for the 50th unit. The learning curve formula can be expressed

Whether it is by making mistakes‚ by observing others‚ or repeating a process over again‚ it is human nature to learn. In their book The Bell Curve‚ Richard Herrnstein and Charles Murray disagree and hold the position that human intelligence is inborn and measurable by IQ‚ which In turn shows how much success a single individual will have in life. The Bell Curve supports a class system‚ arguing that the intelligent are likely to become ever more dominant and prosperous‚ while the unintelligent are falling
