The image illustrates a use case diagram for a hotel management system with multiple actors and their interactions. The primary actors include the Hotel Guest, Restaurant Receptionist, Management, and IT Manager. The Hotel Guest interacts with the system through various use cases such as searching availability, making a booking, check-in and check-out processes, making payments, requesting room service, scanning a QR code for in-room services, and providing feedback. The Restaurant Receptionist's use cases involve login, report generation, receiving orders, food delivery, and updating the menu. Management's responsibilities are analyzing business performance, logging in, and developing strategies and marketing plans. The IT Manager's role encompasses user management, cybersecurity, collecting and measuring data, and reporting or updating hardware/software systems. All these interactions are mediated by the central system, which processes and facilitates the various services and management functions within the hotel.
