Textbook Problem

Study Figure 15.8, showing the level 0 DFD of the cost accounting system. Note that the raw materials and finished goods inventory processes are outside the context of the system shown (i.e., the DFD covers work-in-process inventory only).

1. a. Draw a context diagram for the system as it currently exists.
2. b. Assume that both the raw materials and finished goods inventories are within the system context. Prepare a context diagram for the revised system, and redraw Figure 15.8 to reflect the revised system. Ignore the ordering of raw materials from vendors; start the raw materials process with the receipt of goods. Also ignore the issue of finished goods. Keep the assumption that the company uses standard costing for all inventories.
