Scenario: Airport Customer Relations Management System
A local airport has recently upgraded its infrastructure to be able to accommodate international
flights. Airport management is expecting an influx of tourists. To ensure the all-round success of
this new endeavour, a heavy emphasis is being placed on keeping visitors to the airport as
satisfied with the airport and its amenities as possible. To aid in maintaining good customer
relations, the airport has decided to invest in the development of a new Customer Relations
Management System, which would be accessible online via kiosks strategically placed around the
airport as well as a downloadable mobile application.
The new system is envisioned to offer customers the following:
1. Information: updates on flights, airport amenities and services available at the airport;
2. Navigation capability: GPS navigation to various amenities and boarding gates;
3. Instant connection to medical and ambulatory services for any medical emergency.
