A language for defining design discipline characteristics is proesign discipline characteristics such as abstraction levels, design object classifications and decompositions, design objectives, and design methodologies can be defined in a simple machine and human readable form. The language, DDDL, has led to the development of a user interface for Minerva II, a design process management tool, which, when configured with a design discipline description, can be used to aid teams of designers in the solution of complex multi-disciplinary design problems. DDDL and user interface examples are presented.
