Estimation of costs can be done with the help of two systems known as Traditional costing and Activity based costing. Traditional cost system was developed by the organization, General Motors. The organization used this system to calculate the total manufacturing cost that is sum of all the costs related to individual operations. However, the cost that matters the most to organization is profitability, which is required for improving the competitiveness. This cost estimation is done by activity based costing. The basic preface of activity based cost system is that the organization is an integrated process and operates when there is proper supply of parts and raw materials at respective plants. It continues until the final good reaches the customer (Drury, 2008). The traditional cost accounting system is based on the factors such as Wages and salaries, employee benefits, supplies, traveling allowances, depreciations and other fixed charges, operating expenses and miscellaneous (Dury, 2008). Activity bases accounting system is based on evaluation of suppliers, purchase order, expedite deliveries and supplies, purchase orders, expenditure on internal process, maintaining check of item quality and deliveries, resolving the problems and internal administration.

The main problems related to use of traditional costing system is limited economic focus. The benefits offered are intangible and remain unmeasured. These all the factors that might prove to be bottleneck for the company can be cleared by the help of activity management cost (Thomsett, 2002).

Activity based costing system follows the mentioned principles •It measures the actual performance of the organization, taking into consideration every cost associated with activities. •With the help of this system the managers there is proper relation of consumption and expenses is maintained. •In activity based costing cost of activities are calculated based on resources that are consumed. •This method helps the managers to draw proper insight of sources of cost and the impact that might happen on and due to decisions taken. •Activity based costing system enables manager to realize the performance...
