Document Summary
Learning curves: the time required to perform a task decreases with increasing repetitions. Human performance of activities generally improves when the activities are done on a repetitive basis i. e. the time required to perform a given task decreases with increasing repetitions. Number of tasks needed to realize the major portion of the improvement is: A function of the task being done. If the task is: short and somewhat routine. Only a modest amount of improvement is likely to occur and generally occurs during the first few repetitions. If the task is: fairly complex and of longer duration. Learning factors have little relevance for planning and scheduling routine activities. They do have relevance for complex repetitive activities. Fig 7s1 on page 313 shows a typical learning curve. Note: the unit time will never be zero! 1936 thomas wright of curtiss-wright aircraft company: Described how the direct labour cost of producing a certain airframe decreased with experience.
