PROJECT: ORDER PROCESSING SYSTEM
Updated Homework 2
SUMMARY:
The Sales Team receives an order from the Customer and
checks the inventory. If the item is in stock, the Sales Team
sends an order confirmation to the Customer. However, if the
item is not in stock, the Sales Team sends a backorder
notification to the Customer and offers an alternative or
revised order if possible. The Customer then confirms the
revised order, if applicable.
Once the order is confirmed, the Sales Team processes the
order and generates an invoice. The Billing Team then sends
the invoice to the Customer for payment. Once the Customer
pays the invoice to the Billing Team, the Billing Team records
the payment and proceed with the order

(their internals are hidden from our perspective and from the point of modelled process it is out of control)
