![]() ![]() (See SysML «view» stereotype of Package for View notation and semantics.) Modelers should feel free to modify the following Views and their contents consistent with their chosen Model-Based Systems Engineering (MBSE) and/or Model-Driven Development (MDD) methods. Organize your model into well-defined Views along the lines of the following, where UML and SysML diagrams are combined in a complementary manner:.Check out for candidate SysML modeling tools that support SysML + UML2 mixed language usage. UML modeling tools that support SysML vary widely in this regard, with some being more restrictive than others since the OMG specifications generally defer this sort of implementation detail to vendors. Select a UML modeling tool that correctly implements SysML as a UML2 compliant profile and allows you to populate SysML diagrams with UML constructs and populate UML diagrams with SysML constructs. So, given the "Tower of Techno-Babble" anti-pattern described above, how can a team comprised of both Systems Engineers and Software Engineers specify a model that harmoniously combines SysML and UML model elements? The following outlines a technical approach based on the transitivity of requirements traceability dependencies (notably «satisfy» and «refine»), that has proven effective on numerous large, mixed modeling language projects: This misguided and poorly-executed design philosophy has resulted in a "Tower of Techno-Babble" anti-pattern for users who want to synergistically combine the OMG's most popular visual modeling languages (UML, SysML, BPMN), and it has resulted in a "Meta-Babble" anti-pattern for vendors relying on the gratuitously-complex Meta Object Facility (MOF) and XMI for reliable model interchange. It appears that the Object Management Group (OMG) is following a "family of languages" visual modeling design philosophy, as opposed to the "unification of languages" design philosophy that dominated UML 1.x adoption and revisions during the late 1990's and early 2000's. In practice, unfortunately, users frequently find it confusing and problematic to combine SysML and UML model elements in the same model, just as they find it befuddling and vexing to interchange SysML and UML models across supposedly XMI (XML Model Interchange) compliant modeling tools.
