Revamping Business Processes
The following is the sales order business process for MusicMan. Draw the As-Is process model based on the following narrative:
1. A customer submits an order for goods to MusicMan, a music retailer, through an online mechanism such as a browser-based order form. The customer supplies his or her name, the appropriate email address, the state to which the order will be shipped, the desired items (IDs and names), and the requested quantities.
2. The order is received by a processing system, which reads the data and appends an ID number to the order.
3. The order is forwarded to a customer service representative, who checks the customer's credit information.
4. If the credit check fails, the customer service representative is assigned the task of notifying the customer to obtain correct credit information, and the process becomes manual from this point on.
5. If the credit check passes, the system checks a database for the current inventory of the ordered item, according to the item ID, and it compares the quantity of items available with the quantity requested.
6. If the amount of stock is not suffi cient to accommodate the order, the order is placed on hold until new inventory arrives. When the system receives notice of new incoming inventory, it repeats step 5 until it can verify that the inventory is suffi cient to process the order.
7. If the inventory is suffi cient, the order is forwarded simultaneously to a shipping agent who arranges shipment and an accounting agent who instructs the system to generate an invoice for the order.
8. If the system encounters an error in processing the input necessary to calculate the total price for the invoice, including state sales tax, the accounting agent who initiated the billing process is notifi ed and prompted to provide the correct information.
9. The system calculates the total price of the order.
10. The system confi rms that the order has been shipped and notifi es the customer via email.
11. At any point in the transaction before shipping, the order can be canceled by notifi cation from the customer.
