This paper presents the traceability metamodel for Business Process Model and Notation (BPMN) and its implementation in Cameo Business Modeler plug-in for MagicDraw. There is no public standard traceability metamodel defined for BPMN yet. We present solutions that we have already applied in practice: we improve the traceability of BPMN models by defining derived properties that are calculated by a modeling tool on the fly. In contrast to other existing solutions, this approach does not require additional efforts from users for defining and maintaining traceability, and does not overload projects with redundant information. Using this approach, CASE tool developers are able to supplement their tools with traceability analysis means allowing users to access traceability information easier, to check completeness and correctness of BPMN models, and to analyze the impact of changes.

Model‐Based Systems Engineering (MBSE) is a natural choice for engineering complex systems of systems that involve hardware and software components, deal with a huge number of heterogeneous requirements, and require solid verification and validation at multiple levels. However, industrial MBSE adoption requires solving multiple problems. Most of them originate when MBSE is incorporated into the production environment. For enterprise‐level industrial solutions, this means integration into the Product Lifecycle Management (PLM) tool chain. This integration covers requirements, product line, variability, design, simulation, BOM, configuration, version, and CAD drawings management. The problem is that there is no clear path for integration. Due to the various types of data that can be interchanged between PLM and MBSE, the existing integration solutions are patchy and driven by clients use cases only. There is not enough information about recommended MBSE – PLM integration practices, use cases, and methods. This is a huge problem in the context of large‐scale partnerships working on mission‐critical systems, where engineering data has to be processed and managed in the most consistent way so as to be used by all the partners and through the different PLM activities. In this paper we will overview real‐world PLM and MBSE integration cases from our company experience. We will map a path toward the right solution, and will dive deep into the practical side of Product Line Engineering (PLE) and MBSE integration.
