Hilton Hospitality Hackathon 2024
September 20th – 22nd, 2024
Theme: Delivering Exceptional Experiences for the Hotel Guest of the Future
Best Visualization Award
Winner: Comfort Champions (Heidi Ongkowijaya and other members)
To alleviate the workload of the hotel front desk team, especially amid staffing shortages in the hospitality industry, we proposed incorporating an additional simple feature on existing Hilton mobile app. Our analysis shows that guest satisfaction scores are significantly affected by staff availability.
The app feature will connect guests directly with relevant departments, such as housekeeping, concierge, and restaurants, for common requests, bypassing the front desk. We streamlined the user interface to simplify navigation. Additionally, the app will include a feedback mechanism for guests to confirm when their requests have been fulfilled, ensuring a closed feedback loop.
