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
- 1. Qualified hardware and software.
- 2. Lab environment that has been tested to assure its operability and has been accepted by QA.
- 3. Preliminary system test procedures.
- 4. TAIR books that are ready to record the results of system testing; these are jointly prepared by QA and Engineering.
Process
Test procedures based on system-level requirements and architecture/designs are completed.
Qualified hardware and software end items are installed in the lab environment, as well as lab hardware and software necessary to test/diagnose the system at this level. Test procedures undergo a dry run and are updated as necessary, then rerun “for credit.” TAIR books are updated during the testing to record the results as they occur. Test results are captured, analyzed, and documented in system test reports.
Anomalies are recorded, analyzed, and corrected. Regression testing is conducted as needed.
Requirements Traceability Matrices/Verification Cross-Reference Matrices (RTM/VCM) are updated to reflect the successful verification of requirements that have been allocated to this level of testing.
SE is responsible for generating the associated test procedures, conducting dry runs, updating the test procedures as needed, performing the official testing, and documenting the results.
Outputs
- 1. System test reports.
- 2. Anomaly reports, as needed.
- 3. Updates to end item documentation as a result of anomaly corrections and regression testing.
Milestone Reviews
There are no formal milestone reviews in this phase.
