The goals of our unification efforts were to keep it simple, to cast away elements of classic Booch, Objectory, and OMT that just didn’t work in practice, and to add only new elements that let us address modeling problems that neither Booch nor Objectory nor OMT had yet addressed. Because we were in effect designing a new language (albeit a graphical one), we had to strike a proper balance between minimalism (everything is text and boxes) and overengineering (having an icon for every conceivable modeling element). To that end, we were very careful about adding new things, because we didn’t want to make the unified method more complex. Along the way, however, we found some things that we genuinely needed to add, because they were useful in practice in other methods and previously had been handled only informally in either Booch or OMT. Responsibilities are a good example of this. Responsibilities become first-class citizens in the Unified Modeling Language, reflecting the fact that resp
