During the Operational Test and Evaluation phase the new system/subsystem is installed in operational aircraft and exercised by the end user community (Launch airline customer). While testing up to this point has focused on assuring that identified requirements have been verified, this phase focuses on validation, i.e., assuring that the end-users needs regarding the system…

During the System Detail Test and Evaluation phase, the system is verified and tested in the aircraft environment during flight. SE’s Test Integration function plays a key role in the planning for execution of the flight tests, including development of the detailed flight test procedures. Inputs Process Safety of flight certification is completed for the…

During the Installation and Checkout Test phase the qualified/approved hardware (H/W) and software (S/W) are installed in the test aircraft(s) and tested on the ground. These tests also utilize systems as needed that are already on the aircraft. Inputs Process Instructions for performing the installation, usually included in the Temporary: 1 − X (T: 1 − X) Package, are performed.…

The System Integration and Test phase brings the qualified hardware and software together into a lab environment for verification at the system or subsystem level. Where a lab of suitable fidelity is not available, this phase may be performed on the aircraft for selected items. 5.4.1 Inputs Process Test procedures based on system-level requirements and…

The Item Qualification Testing phase results in the formal verification of end item requirements. Inputs Process The hardware and software end items are installed in the approved test environments. Item qualification dry runs may be conducted, and the work products and test procedures are updated as necessary. Testing is then conducted in accordance with the…

During the Subsystem Test and Integration phase, maturing elements of the hardware and software are brought together and exercised, with corrections processed as needed. These tests are conducted in accordance with their respective test plans and may be conducted iteratively and/or in parallel as appropriate. Inputs Process Integration and verification as previously described continue up…

During the Developmental/Unit Test and Integration phase, engineering components are physically integrated into successively larger aggregates of hardware and software. Tests are developed and conducted to assure that the functions defined by the preliminary and detailed designs are being accomplished, including performance requirements, error detection and recovery, and degraded operations. Inputs Process The engineering organizations…

The presents an example of an Integration Plan and Test Strategy based on a real-world aircraft development program. The various phases of test and integration are described, with inputs, process description, outputs, and milestone reviews provided for each phase discussed. Systems engineering works jointly with the Integrated Project Teams (IPTs) responsible, to assure that all…
