McRonald, a fast$-$food hamburger restaurant, uses a comprehensive and precise process to manage and prepare customer online orders, ensuring each meal meets the high standards of quality and service for which the restaurant is known. When a customer places an order, the order management system first checks the availability of all necessary ingredients. If an ingredient is unavailable, the customer is promptly informed, the order is cancelled, and the missing ingredients are reordered from the supplier to restock the inventory. If all ingredients are available, the system sends a SMS to inform customers of the approximate pickup time.

Once the order is accepted, the kitchen team begins preparing the burger. After the burger is ready, the team checks if the order includes additional items such as chips, drinks, and desserts. Each of these items is then prepared and assembled according to the specifics of the order. Finally, the complete order, including the burger, any sides, drinks, and desserts, is beatly packed into a paper bag. This bag is then placed at the pickup counter ensuring that ne order is ready to be enjoyed promptly and conveniently.
