The following narrative describes the processing of customer mail orders

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 household 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). (Complete only those requirements specified by your instructor. Also, as directed by your instructor, complete P 9- 2b, c, e and/ or f using Micro-soft Visio or similar diagramming software.)

a. Prepare a table of entities and activities.

b. Draw a context diagram.

c. Draw a physical data flow diagram (DFD).

d. Prepare an annotated table of entities and activities. Indicate on the table the groupings, bubble numbers, and bubble titles to be used in preparing a level 0 logical DFD.

e. Draw a level 0 logical DFD.

f. Draw a systems flowchart.

g. Prepare a control matrix, including explanations of how each recommended existing control plan helps to accomplish—or would accomplish in the case of missing plans—each related control goal. Your choice of recommended control plans may come from Figure / Exhibit or Figure / Exhibit, as appropriate. Be sure to tailor the matrix columns to conform to the specifics of the Eye-Dee-A-Pet, Inc. system. In doing so, assume the following two operations process goals only:

  • To provide timely acknowledgement of customer orders
  • To provide timely shipment of goods to customers

h. Annotate the systems flowchart prepared in requirement (f) to show the location of each control plan listed in the control matrix.
