Many companies use both the job order and the process cost methods. For example a company manufacturing a railway car to the customer's specifications uses job order costing to accumulate the cost per railway car. However, the multiple small metal stamping required for the job are manufactured in a department that uses fast and repetitive stamping machines. The cost of these is stamping is accumulated by process costing. Although the company is using both job order and process costing in this example, there is no real blending of the two methods because they are employed in separate operations other systems exist in which a real blending of job order and process costing does occur.
