Abstract
The central conclusions of this effort are that model-based methods for procurement and systems integration are effective for improving systems engineering outcomes; model-based methods identified many of the risks that were manifested in the lab. Most of the time or capability-loss issues encountered in the lab were related either to software configuration or network configuration. We demonstrated a workable path to successful application of MBSE and ACVIP for major embedded systems integration activities. We observed successful adoption and application of MBSE and ACVIP by FARA performers and successfully applied performer- generated ACVIP artifacts. Galois’s role in OSVD allowed us to contribute model-based risk virtual integration assessments to help reduce risk for physical integration efforts. By applying ACVIP to OSVD, we were able to correctly predict integration risks that were later realized in lab activities (specifically network configuration errors). In this case, we found that the best predictor of problems in physical asset integration was ambiguity rather than incompatibility, in design artifacts. The key remaining challenges for broad realization of the benefits of MBSE and ACVIP are dealing with culture change and scalable deployment of digital engineering environments across organizational boundaries.
