In managementmodels of the learning curve effect and the closely related experience curve effect express the relationship between equation [ clarification needed ] and efficiency or between efficiency gains and investment in the effort. Experience shows that the more times a task has been performed, the less time is required on each subsequent iteration. This relationship was probably first quantified in by an engineer at Curtiss-Wright in the United States where it was determined that every time total aircraft production doubled, the required labour time decreased by 20 percent.
Learning curves are steep in history and have several alternate names such as improvement curves, progress curves, startup functions, and efficiency curves. Its use was amplified by experience in connection with aircraft production in WWII. Initially, it was thought to be solely due to the learning of the workers as they repeated their tasks.
The learning curve relates to the observed tendency that workers become adept at a task, the more often they perform it. Hence the task will take less and less time the more often it is performed. This is quite a simplistic way to look at the learning curve but there are many factors to consider when applying the learning curve and ultimately, understanding when and how to use it.

Learning Curve Theory is concerned with the idea that when a new job, process or activity commences for the first time, it is likely that the workforce involved will not achieve maximum efficiency immediately. Repetition of the task is likely to make the people more confident and knowledgeable and will eventually result in a more efficient and rapid operation. As a consequence the time to complete a task will initially decline and then stabilise once efficient working is achieved.
The purpose of this article is twofold: first, it is to summarise the history of the learning curve effect and help candidates understand why it is important. Second, it is to look at what past learning curve questions have required of candidates and to clarify how future questions may go beyond this. In practice, it is often found that the resources required to make a product decrease as production volumes increase.
Provided by James R. Martin, Ph. The theory of the learning curve or experience 1 curve is based on the simple idea that the time required to perform a task decreases as a worker gains experience.
The learning curve concept was formally introduced by T. Wright Wright, through his pioneering empirical study on the productivity trends of the production of aircraft. Since that time, and especially following World War II, the learning curve concept has been extensively researched and applied in numerous settings. While the most publicized applications are related to the production of aircraft and defense products, other products have also experienced similar learning trends.
