Imp Variance

Important of variance

Costs of production are effected by internal factors over which management has a large degree of control. An important job of executive management is to help the members of various management levels understand that all of them are part of the management team. Standard costs and their variances are an aid to keeping management informed of the effectiveness of production effort as well as that of the supervisory personnel. Supervisors who often handle two thirds of three fourth of the ringgit cost of the product are made directly responsible for the variance which, show up as materials variances (price, quantity, mix, and yield) or as direct labor variances (rate and efficiency). Materials and labor variances can be computed for each materials item, for each labor operation, and for each worker. Factory overhead variances (spending, controllable, idle capacity, volume, and efficiency) indicate the failure or success of the control of variable and fixed overhead expenses in each department.

Variances are not ends by themselves but springboards for further analysis, investigation, and action. Variances also permit the supervisory personnel to defend themselves and their employees against failures that were not their fault. A variance provides the yardstick to measure the fairness of the standard, allowing management to redirect its effort and to make reasonable adjustments. Action to eliminate the causes of undesirable variances and to encourage and reward desired performance lies in the field of management, but supervisory and operating personnel rely on the accounting information system for facts which facilitate intelligent action toward the control of costs.
