Manufacturing: The Importance Of Variance Analysis In Manufacturing

870 Words2 Pages

Variances are the differences the standard (expected) and actual results, and the process with which those differences, between actual and expected figures, are found is called variance analysis. Variance can be favorable and un-favorable, under costs variance if actual figures exceeds the standard figures it is called un-favorable variance, while if actual figures become smaller than standard it is called favorable variance. In the case of revenues if the actual surpasses the standard, it becomes favorable in the event where actual numbers are smaller than standard those are called un-favorable variance.

Constant stage is defined as, in the manufacturing process the period in which the output of labor time per hour stabilizes is known as constant stage. In order to give brief explanation of constant stage we have to understand the learning curve and predecessor activities of constant stage, in an organization when new product or a new manufacturing process is introduced, the direct labor hours required to produce one unit would decrease as laborers become more familiar with the process. It is a established fact that the average time required to complete one unit will decrease at constant rate from initial unit produced until the complete learning has been achieved. Such effect of learning process on laborers is called learning curve. The learning curve is computed on statistical determinations that as aggregate number of units produced doubles the average direct labor time required per unit will decrease at constant percentage which is called cost reduction percentage. The time period to which the product output per hour increase is known as learning stage. A certain stage comes in the production process whereby any further improvements in output per hour can only be achieved by changing the nature of the production process itself or by changing or improving the equipment being used for production, the period in which the output per hour stabilizes is known as constant stage. Once constant stage is achieved and long time has been passed there exists a possibility that the productivity may start to decline because the excitement, challenges of learning a new production are
