In this communication diagram for a Restaurant Management System, the Restaurant Manager serves as the central entity connecting and coordinating with all other components. The process begins with the customer placing an order through the manager, who checks the inventory for item availability. After confirming availability, the manager sends the order to the kitchen for preparation. Once ready, the manager serves the order and generates a bill through the billing system. The billing system processes payment and updates the inventory. This structure ensures smooth coordination among all entities, centered around the Restaurant Manager.
