T1 = Hours to produce the first unit. b = (Log of the learning rate/Log 2) = Slope of the learning curve. If the learning rate for a given operation is 80%, and the first produced unit took 1.000 hours, the hours needed for the thirteenth unit can be calculated as follows: TN = T1(Nb).
Learning curve for a single subject, showing how learning improves with experience. A learning curve averaged over many trials is smooth, and can be expressed as a mathematical function.
