In most manufacturing businesses, production costs are accounted for using one of two types of cost accumulation system: a job order cost system, which was discussed in Chapter 5, or a process cost system, which is discussed in this chapter. This chapter begins with a discussion of the process cost accumulation concept and the environment in which a process cost system is appropriate. In the next section, the process cost accumulation concepts are illustrated by examples of cost of production reports along with the general journal entries required to record the charges to producing departments for costs incurred during the period and for transfers of products from one department to another and finally to Finished Goods Inventory.
