The document discusses a case study of a queue management system implemented by the Ministry of Foreign Affairs in Romania to manage customer service at its consulates. The system aimed to offer the highest standard of service according to EU norms and provide a quick, half-automated service using web forms and passport identification. It resulted in a 38% decrease in waiting times, a 23% increase in staff efficiency, and the ability to serve 1/3 more customers daily across 50 countries on 4 continents, serving over 1.8 million customers a year. The system features touchscreens, printers, barcode scanners, and passport readers to automate processes like appointment booking, queuing, and customer identification.
