NOTE 1: The System integration test will focus mainly on interfaces, data flow, functionality of the system elements etc..

NOTE 2: The System integration test should verify that only allowed application parameter combinations can influence system functionality and that wrong parameter or parameter combinations are failsafe.

NOTE 2: The System integration test process should start with the beginning of the system development process. There is a close link from System Requirements Analysis ENG.2, System Architectural Design ENG.3, or Requirements Elicitation ENG.1 in developing test cases and testable requirements.

NOTE 3: The system integration strategy contains different approaches of integrating system elements depending of the changes (e.g. changed hardware items, new integrated software). The integration strategy also includes the most suitable test methods to be used for each integration approach.

NOTE 4: The identified system elements and the order of integration will have an influence on system integration test strategy.
