I really like DFD's ... but do you know a free (or inexpensive) program to draw them? PoweDesigner does it, but it's pretty expensive (although good). I used to use something called DFDiagrammer, (or some name like that) but support stopped at Windows XP. And by draw them, I mean draw them and enforce the rules, ensure that (or check if) child process diagrams have in and out DF's consistent with the process, check (or ensure) that processes don't invent data - ie, they can only output what they can get from processing input ... also and 'exploded child diagram' - a single diagram showing all lowest level child processes - is very useful.
Anyone want to write a DFDDraw for fun?
