System engineers have responded to the need for more rigor by adopting the UML and SysML standards. The standards are complex, and don’t provide guidance on how best to apply modeling techniques with these languages to effectively specify requirements and architectures, nor how to use modeling to perform trade studies and the various kinds of analyses required by systems engineering.
