== S*Models and S*Patterns may be expressed in any system modeling language (e.g., SysML, IDEF, etc.) and managed in any COTS system modeling tool or repository, by an S*Metamodel mapping or profile. PBSE builds on long historical work in patterns, now improved as MBSE models (many historical engineering patterns were not explicit MBSE models), expansion of pattern scope to whole system families, platforms, and domains (as opposed to smaller-scale localized patterns). An explicit foundation based on a stronger MBSE metamodel expresses systemic phenomena, critical to engineering applications needing a clearer connection to scientific understanding of systems phenomena. ==
== The general PBSE approach to enhanced MBSE is being shared through and explored by the members of the Patterns Working Group of the INCOSE MBSE Initiative. This cross-industries team has been and continues pursuing a number of PBSE applications and projects (including joint projects with other INCOSE working groups) which are shared through the INCOSE MBSE Challenge Team’s MBSE wiki / web site posted resources, reference, and information assets. Refer to the Resources below. Where commercial support may be requested, ICTT System Sciences and its partners provide related services, and the third party COTS tools noted above are supported by their commercial suppliers. S*Modeling elements are also taught as systems competencies for engineering undergraduates at Rose-Hulman Institute of Technology, the original academic parent of ICTT. ==
