Case Study: Flight Application
We’ll illustrate how the phased approach is applied by examin-
ing the operation of a web-based portal that allows customers
to book airline flights.
The portal is an easy-to-use, straightforward solution that
allows customers to search, select, and book flights in the flight
database. The system interfaces with the centralized booking
system based on the Systems, Applications, and Products in
the Data Processing (enterprise resource planning [ERP])
financial module.
Customers have to register before they can use the system. The
customer-related information is stored in the centralized cus-
tomer relationship management (CRM) system, along with
users’ passwords.
