Learning curves
Introduction: Wright’s Law
In some industries, there is a tendency for labour time per unit to reduce
in time. As more of the units are produced, workers become more
familiar with the task.
Average time per unit for
all units produced to date Total time Total time
Total number of units Output
produced
The learning curve is the mathematical expression of the commonly
observed effect that, as complex and labour intensive procedures are
repeated, unit labour times tend to decrease.
