What does UML 2.0 bring to the graphical modelling landscape? By Vanessa Knivett.

With system complexity on the increase and time to market pressures tightening, system designers have to work harder and smarter than ever. And, in their efforts to find solutions to increasingly difficult design problems, they find themselves struggling to find terms to describe them.
