Adapting Progressive MBSE Development to Document Based Contracts

Every new program executed by BAE Systems Space Systems continues to improve and mature the Model Based Systems Engineering (MBSE) development position. While the benefits of MBSE are realized internally, each program is forced to regress to a legacy document-based structure for customer interaction and contract deliverables. Until there is a paradigm shift in how contracts are fulfilled, there will be a need to adapt the model to traditional document deliverables. This paper discusses the challenges of adapting Model Based System Engineering models and development processes with legacy document based contracts through document representation within the model combined with document exportation. BAE Systems has embraced Model Based Systems Engineering since 2016 and continues to expand its application. Satisfying document-based deliverables without duplication of effort and information is essential to continue the rapid adoption of Model Based Systems Engineering.
