There exist some fields in which the learning curves can be applied; they have a much wider applications including manufacturing and marketing strategy. However, they underlay the concept of continuous improvement, pricing decisions, work scheduling, standard setting, direct labour budget etc. Learning curve states that decreasing man hours are required to accomplish any repetitive task as the operation is continued; then knowledge of learning curve can be useful both in planning and control. Estimates of learning curves are used in many applications in organizations and they can be effective with the job which is repetitive in nature particulars with same machinery and tools; thus this study aims at improving the application of the learning curve which describes how knowledge is acquired and retained when people repeat a process. The overall purpose of this report is to determine whether or not the learning curve theory can be replicated. Data will be gathered based on the England flyer folding instructions; thereafter we will be plotting the learning curve by calculating the cumulative average, estimating the table of unit improvement curves and determining the learning rate.
When a new product or process is started, performance of worker is not at its best and learning phenomenon takes place. As the experience is gained, the performance of worker improves, time taken per unit reduces; and then his productivity goes up. Thus, people who learn always increase their experience, they gain skill and ability from their own experience and the results throughout processes are improved. The usual use of learning curves is to estimate the labor hours and thereby much of the cost, of a manufactured good that is built in significant quantities.

Excerpt from the Book
1.1 Background and motivation
When a new product or process is started, performance of worker is not at its best and learning phenomenon takes place. As the experience is gained, the performance of worker improves, time taken per unit reduces; and then his productivity goes up. Thus, people who learn always increase their experience, they gain skill and ability from their own experience and the results throughout processes are improved. The usual use of learning curves is to estimate the labor hours and thereby much of the cost, of a manufactured good that is built in significant quantities.It can be applied to the individuals or organisations based on several assumptions:
• Standardised product: the product isn’t changing; then every time the product changes, the learning effect will stop and start again.
• Little or no breaks in production & little or no labour turnover.
• The unit time will decrease at a decreasing rate.
• Complex operation: simple operation doesn’t require learning.
• The reduction in time will follow a predictable pattern.
• The process is labour intensive: the labour determines the speed of the process.
The learning curve is a line displaying the relationship between unit production time and the cumulative number of units produced. Learning curves have been applied to creation of documents, boring of tunnels, drilling of wells, upgrades of previously manufactured products, and many other repetitive activities This time around, two learning curve models are in widespread use: the “unit” (U) model, due to Crawford, and the “cumulative average” (CA) model, due to Wright. Some manufacturing companies also apply “learning” to the purchase of raw materials and also to the purchase of manufactured components from other companies (Evin Stump P.E). Then, an organization also acquires knowledge in its technology, its structure, documents that it retains, and standard operating procedures [1].
