You have been approached by the Domino's Pizza franchise to redesign the computerised system customers use to order menu items for delivery online. All goods are sold on their online menu has a QR code to identify the menu item. Each Domino's Pizza shop has an address and a branch name. For each order, a separate delivery ticket is maintained, and the computer system will separately track the deliveries to customers. The online computer system will also send the delivery ticket to the closest Domino's Pizza branch to cook the order. Only when the customer pays for their order will the Domino's Pizza branch start cooking the food. The Domino's Pizza branch notifies the computerised system that they have begun cooking the order. While the order is being cooked, the computerised system contacts UberEats to send a person to the Domino's Pizza branch to deliver the order, giving a time when they need to arrive to pick up the order. When the UberEats delivery person arrives at the Domino's Pizza branch, the delivery person uses the computerised system to note they have picked up the order and delivering to the customer. A message is sent to the customer via phone text message that their order is on the way. When the delivery arrives and given to the customer, the UberEats delivery person uses the computerised system to note the delivery was successful, closing out the delivery ticket.
