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).
The learning curve on the left is shallow. That means that for every unit of time you put into it, you get less back in terms of ability. The learning curve on the right is steep. That means that for every unit of time you put into it, you get more back in terms of ability.
