In this module, the discussion focuses on the similarities and differences among costing systems. You should be able to describe the systems and also identify which system would be most appropriate for a company and why that would be the case. Describe the differences between job order costing, process costing, and Activity Based Costing (ABC). What are the advantages and disadvantages of each system? Imagine a company that you might be a manager for. Describe that company and what their major product or service would be. Then, tell which cost system would be best suited to that firm and why.
