What is SysML/UML?

SysML (Systems Modeling Language) is a general-purpose modeling language for systems engineering. It supports the specification, analysis, design, verification, and validation of a broad range of complex systems. UML (Unified Modeling Language) is a general-purpose, developmental, modeling language in the field of software engineering, that is intended to provide a standard way to visualize the design of a system. SysML is often used to model hardware, software, information, personnel, procedures, and facilities, whereas UML primarily focuses on software systems. SysML reuses a subset of UML and adds extensions to provide specific capabilities needed for systems engineering, such as requirements modeling, parametric diagrams, and allocation tables.
