Assume that GBI is currently working with a manual system. The company uses the following 26 steps when they sell standard goods to the customers:

1. A customer sends a purchase order for off-road bicycles to a GBI employee.
2. A GBI employee compares the customers purchase order to determine if the customers master data is in the system and is correct.
3. If the customer master data is not in the system or is incorrect, then the master sales and distribution data (such as company address, contact person, phone numbers, etc.) for the customer is entered by a GBI employee.
4. If the customer master data is not in the system or is incorrect, then the financial data (such as banking information and GBI reconciliation account number) for the customer is entered by a GBI employee.
5. If the customer master data is not in the system or if the customer would like to change credit terms or limits, then a GBI employee checks the credit rating of the customer and assigns a credit limit and credit terms.
6. A GBI employee checks inventory availability.
7. If the customer can be extended credit and inventory is available, a GBI employee creates a sales order.
8. A GBI employee creates an order acknowledgement and sends it to the customer.
9. A GBI employee records the sales order.
10. A GBI employee creates a picking ticket to fill the customers order.
11. A GBI employee picks the goods (the bicycles) from the picking ticket.
12. A GBI employee creates a packing slip and a mailing label.
13. A GBI employee puts the packing slip into a reinforced packing container with the goods, seals the container and adheres the mailing label to the container.
14. A GBI employee moves the goods from the inventory control area to the shipping dock.
15. A GBI employee creates a shipping manifest.
16. A GBI employee places the goods to be shipped on the truck.
17. A GBI employee gives the shipping manifest to the truck driver.
18. A GBI employee creates a shipping document to show that the goods have been shipped.
19. A GBI employee records that the goods have been shipped.
20. A GBI employee creates an invoice with a remittance advice and sends it to the customer.
21. A GBI employee receives the payment from the customer with the returned remittance advice.
22. A GBI employee records the payment from the customer.
23. A GBI employee takes all of the payments for that day and makes up a deposit slip for the bank.
24. A GBI employee deposits the cash in the bank.
25. A GBI employee records the bank deposit.
26. A GBI employee reconciles bank deposits with the cash receipts on a daily basis.
