LEARNING CURVES FOR ESTIMATING
A learning curve is a line that shows the relationship that exists between the direct labour hours per unit with that of cumulative quantity of a product produced or service offered. T.P. Wright was the man known behind introduction of learning curve concepts to the aircraft industry(Jaber, 2011). The theory describes the rise in the number of products produced and the number of corresponding resources required for one unit of production. This theory is provided some attributes that human being having the ability to learn from their past experiences. The learning process starts from the human being repeating the same tasks and acquiring skills from their experience. The skills gained are used to increase the knowledge of the task being done, to improve work performance, to become a familiarity with the tasks, for better and effective methods and tools and better coordination. This theory applies to the projects that are repetitive, continuous and identical. The task should be repeated during the same operation. Learning curve theory states that if the production of a a good increases by a double unit, then the average costs i.e. direct labour hour decreases by a certain percentage of the previous average rate or last unit(Daugaard, Mutti, Wright, Brown & Componation, 2015). Learning rate is the percentage rate that shows the learning achieved in the process.
The application of the learning curve to the project management is accompanied by some few concerns. In project management, some tasks usually take place at unique and different sites conditions. Some tasks are also varied and not repetitive. Some projects have low productivity compared to others. Despite that, the application of learning curve theory has successfully predicted the performance of the projects and has used the linear model in planning methodologies of similar tasks. I have also concluded that there is a high significant positive relationship between the project productivity and the learning opportunity. The straight line curve model is used in many practical applications, and we used this in construction of a concrete building(Jarkas& Horner, 2011).
