Verification Measures are specified for the Mechanical System Verification and Mechanical Component Verification based on the Mechanical System Requirements and Mechanical Component Requirements. Verification Measures are selected according to the Release Scope considering Regression Criteria, including criteria for Regression Verification. The Mechanical System and Mechanical Components are verified using the selected Verification Measures and the Verification Results are recorded. Consistency and bidirectional traceability are established between the Mechanical Component Requirements Verification Measures and Mechanical Component Requirements; and bidirectional traceability is established as chain between Mechanical Component, Mechanical Component Requirements Verification Results and Mechanical Component Requirements Verification Measures. Consistency and bidirectional traceability are established between the Mechanical System Requirements Verification Measures and Mechanical System Requirements; and bidirectional traceability is established as chain between the Mechanical System, Mechanical System Requirements Verification Results and Mechanical System Requirements Verification Measures. Mechanical System Verification Results and Mechanical Component Verification Results are summarized and communicated to all affected parties.
