I used a lot of Objectory and UML diagrams in the nineties, mostly for specification and presentation reasons; don't remember when I used one last time; must be more than ten years ago; from my point of view UML is overkill most of the times; usually takes more time to explain to people what all the sophisticated symbols mean than e.g. simple block diagrams; and systems tend to be so big these days that UML diagrams become too big and confusing; we had the same evolution in hardware development; schematic diagrams were almost completely displaced by hardware description languages (such as Verilog) because systems became much too big to be decently modeled with diagrams.
