Usually I'm able to depict even large, complex systems on a single page and it allows for presentations to both technical and business types that really help get them familiar with the system quickly.

I've also used them to bring developers and other technical staff up-to-speed very quickly on applications they needed to be productive on but had no prior knowledge of.

Hi Alex,
Thank you for the message and for the sample diagram. I agree - from the little I know - that UML diagram is very useful in representing the application. In this particular case (that prompted me to post the initial message) I was looking for a simple "picture-type" diagram for non-technical people. And I found that Power Point has all the tools necessary for creating such "picture-diagram" (where the computers actually look like computers <g>).
Again, thank you. Happy Holidays!
