The objective of this activity is to link Assembly Integration and Verification / Testing (AIV/AIT) processes to a coherent system model in an Model Based System Engineering (MBSE) environment in order to optimise requirements traceability and provide consistent reporting after the execution of operational procedures and functional tests. Description: The on-going shift towards digital system modelling and use of coherent MBSE tools have raised the question of the potential utilization of the models also for later phases of the development cycle. A specific demand for the use of coherent and controlled models has been identified for the AIV process. While generally applicable to any project AIV phase, this demand has been particularly flagged in the frame of the Mars Sample Return (MSR) missions, which are planning to apply a coherent MBSE approach and therefore identified this capability as a clearly mission development enhancing element.Based on the results of previous activities, in particular MARVL and Automated Test Reporting, which have developed system data model exchange platforms and established artefacts for standardised test reporting, and complementing the related activity on the Model Based Engineering Hub, the proposed activity aims to integrate the available information into a system model to employ the consistency enforced in a coherent system model to the verification close-out process. For that purpose, the activity requires to implement those key critical output parameters used in the AIV/AIT process flow into a system model reference platform that are required for the overall system and project management. These artefacts, which are standardised as output of testing and verification activities, are then linked to the respective system model elements to trace the fulfilled requirements, the verified function, test cases and the tested product element. This will also provide configuration control of the as-built status of each model, including representation and link to requirements and standardise feedback from operational procedures, test results, and verification close-outs into the system models to allow for coherent reporting. This traceability shall be available in a user-friendly dashboard environment and provide appropriate views for individual users and make available standardised test reporting. This integration will be tested with a MSR system model test case in order to prepare implementation into project use. It shall be based on the previous work from the atomized test reporting and the development in MARVL and shall be complementary to the MBSE Model Hub development.
