Concept prototype for Business Challenge 2026, team BCR053. Not an official KFC product. The in-store screens (kiosk, counter, kitchen) are in Vietnamese, as guests and staff in Vietnam would see them, and follow the current KFC Vietnam kiosk and app layout so the WaitWise layer is easy to spot. The kitchen is a simulation: waiting times come from the team’s queue model calibrated to the case (Business Challenge 2026, Tables 3–4); sales history by time slot is simulated. Menu, prices and item photos: KFC Vietnam (kfcvietnam.com.vn), retrieved October 17, 2026. No real payment is taken. Voice ordering needs Chrome or Edge and an internet connection.
