Hi Craig,

I haven't used SmartDraw for BA work before, but I used it when doing some patent application diagrams in 2003.  It was a fairly easy and intuitive interface to use at the time, but I don't know if it's changed demonstrably since then. 

If you end up using it for BA work, I'd be interested to know how appropriate you find it.

Hi, I`ve used Smart Draw 2003 edition and 2007 edition.and it is very easy tool for drawing UMLs ,DFDs and for many Graphical MODELS,I advise you to use it,if you realy want very easy tool and nice designed graphics!
