"The Pizza Ordering System allows a web browser user to order pizza jor home delivery. To place an order, a shopper searches to find items to purchase, adds items one at a time to a shopping cart and possibly searches again for more items. When all items have been chosen, the shopper provides a delivery address. If not paying with cash, the shopper also provides credit card information. The system has an option for shoppers to register with the pizza shop. They can save their name and address information, so they do not have to enter it every time they place an order." Draw a use case diagram for a use case for placing an order, Place Order. The use case should show a relationship to two previously specified use cases, Identify Customer, which allows a user to register and log in, and PaybyCredit, which models credit card payments. b. [10 marks] - Suggest why it is essential to distinguish between developing the user requirements and developing system requirements in the requirements engineering process.
