Verification measures are specified for system integration verification of the integrated system elements based on the system architecture, including the interfaces of, and interactions between, system elements. System elements are integrated up to a complete integrated system consistent with the release scope. Verification measures are selected according to the release scope considering criteria, including criteria for regression verification. Integrated system elements are verified using the selected verification measures, and the results of the system integration verification are recorded. Consistency and bidirectional traceability are established between verification measures and the elements of the system architecture. Bidirectional traceability between verification results and verification measures is established. Results of the system integration and integration verification are summarized and communicated to all affected parties.
