22 ■ Optimize Quality for Business Outcomes
System Test
During the System Test, each individual application should
have passed the quality gates for the Integration Test. The Sys-
tem Test often involves large and complex environments with
multiple independent applications working together to sup-
port a business process (Figure 8).

independent applications
The System Test makes sure various applications work
together as the business process requires — flight planning,
ticketing, customer relations. The focus of the System Test is:
 Functional correctness — All interfacing applications
are in place and the application functions correctly in
the defined environment.
 Reliability — The system can perform and maintain its
functions in routine circumstances, as well as in hostile
or unexpected circumstances.
