“The Unified Modeling Language (UML) is a graphical language for visualizing, specifying, constructing, and documenting the artifacts of a softwareintensive system” [1]. This panel of domain and tool development experts discusses the features needed to extend UML to support systems engineering, and together with the audience, investigates the advisability and feasibility of the extensions. Audience participation is an important part of this session. The audience is invited and urged to contribute. While probably in agreement that consistent modeling methods between the two domains will lead to more effective and efficient system development, members of the audience may be concerned that an extended UML may not meet their needs and may be too complex. Since the audience has had diverse experience is engineering systems and using system-engineering methods, audience contributions can lead to an improved UML standard.
