Quantitative analysis





                           Learning curves





                             It has been observed in some industries that 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 and get
                             quicker per unit declines.

               Wright's Law


               Wright's Law states that as cumulative output doubles, the cumulative average
               time per unit falls to a fixed percentage (the 'learning rate') of the previous average
               time.

               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'.
