Question 1:

A description of 14 typical information processing routines is given here, along with 10 numbered segments from systems flowcharts (Figure 4.14).

Match the flowcharting segments with the descriptions to which they correspond. Four descriptions will be left blank.

a. Two documents are sent to an external entity.
b. Data on source documents are keyed to an offline disk.
c. Programmed edits are performed on key input, the data entry clerk investigates exceptions and keys in corrections, and then data on the disk are updated.
d. Inputs stored on two magnetic disks are merged.
e. The computer prepares a report that is sent to an external entity.
f. Output is provided to a display device at a remote location.
g. A batch total of input documents is compared to the total reflected on an error and summary report produced after the documents were recorded.
h. Data are keyed from a remote location.
i. Data on a magnetic tape are printed during an offline operation.
j. Data stored on a disk are sorted and placed on another disk.
k. A report is printed from the contents of a disk.
l. Documents are manually posted to a paper ledger.
m. Magnetic tape input is used to update master data kept on a disk.
n. A printed output document is filed.

Question 2:

Prepare a narrative to describe the system depicted in the flowchart in Figure 4.17 (pg. 141).

These Narratives are to be used in Problems 4-4 through 44 as assigned by your instructor. If you want to test your documentation skills beyond these problems, there are narratives at the end of Chapters 10 through 14.

Narrative 1: Good Buy, Inc (good-buy.com)

Good Buy, Inc. (a fictitious company) sells a variety of consumer products through its Web site, good-buy. Good Buy's IT infrastructure consists of a front-end Web server that interacts with customers and a back-end ERP system that manages the inventory and performs other typical ERP functions. The sales order process begins when a customer logs on to the good-buy.com Web site. The customer requests the company catalog and the Web server obtains the current Good Buy online catalog from the ERP system, which sends the catalog to the Web server, and the server displays it to the customer. The customer selects the items and quantities that he or she wants to purchase; the Web server edits the customer input for accuracy (e.g., ensures that all required fields have been selected or filled in) and sends this list on to the ERP system, where the requested quantities of inventory are allocated for the sale. The ERP sends back to the Web server the quantities that have been allocated, and the Web server displays this information on the customer's screen. The customer verifies that the order is correct and completes the sale by entering his or her shipping and credit card information. The Web server edits this data for accuracy (e.g., ensures that all required fields have been selected or filled in and that the length of the entered credit card number is correct) and sends the credit card information and amount of the sale on to the credit card company. The credit card company sends back a verification number, and the Web server notifies the customer that the sale has been completed by displaying a confirmation number on the customer's screen. The Web server also notifies the ERP system that the sale has been completed, and the ERP system changes the status of the inventory from allocated to sold, prints a picking ticket or packing slip in the warehouse, and records (on the enterprise database) a sale and an account receivable from the credit card company

Question 3: The following narrative describes the processing of customer mail orders at Eye-Dee-A-Pet, Inc.:

Eye-Dee-A-Pet, Inc. is a small manufacturing operation engaged in the selling of digital identification chips that can be implanted into house-hold pets, such as cats and dogs. Customers (e.g., veterinary clinics, animal hospitals) send orders by mail to the sales order department, where sales order clerks open the orders and review them for accuracy. For each order, the clerks enter the customer number, and the computer displays the customer record. The clerk matches the customer information on the screen with the customer order. Assuming that they match, the clerk enters the items and quantities being ordered. The computer edits the order by comparing the input data to customer and inventory master data. Assuming that the order passes the edits, the computer records the order on the sales event data and the sales order master data and then updates the inventory to allocate the ordered inventory. As the order is recorded, it is printed on a printer in the warehouse (the picking ticket).
A copy of the sales order is also printed in the sales order department and is sent to the customer (a customer acknowledgement).
