I use mind maps for just about everything: managing large and small projects, creating and making presentations (beats PowerPoint hands down), analyzing requests for proposals and preparing proposals, analyzing and structuring any problem I endeavor, studying textbooks, keeping a To Do list, etc..
For example, to prepare for the PMP certification exam I took the PMBOK© and made about 80 mind maps. Similarly, I took the PRINC2 manual and made about 110 mind maps that I use to manage any project. The bad news is that I d not use SmartDraw for this but specialized mind mapping software. I do wish, though, SmartDraw would be integrated into that software as is some lesser known drawing tool (I think it is called something like Visio, [smile]).
