Document Summary
The time to manufacture a product drops as more units are produced to a point then the curve levels off. Wright in 1936; he created a learning curve math model. Used to estimate aircraft production labor in ww ii, and since then to estimate many kinds of repeated activities. As people repeat a task again and again, the time it takes to do the task gradually. Rate of learning is greatest at first when ignorance is greatest; rate of learning decreases due to learning decreases as ignorance decreases. At first, learning was attributed to increased motor skills in the workers as they repeated. Later it was realized that management also could contribute to learning with better. This led to new names being applied to the curves, e. g. , improvement, progress, tools and processes startup, efficiency, etc. The learning effect can lead to very large reductions in cost as production progresses.
