About three years ago, I was writing some Excel macros, and it came to demo the prototype. The audience were not interested in “i’ve done this cool stuff in the back end implementation”. One screen searched for some figures, and summarised them. This was not “that visual”. The audience let it be known that they were not that impressed. They were looking for more visual content in the demo.
One thing you can do with a business focussed audience is to offer something which is visual, yet relevant.
Relevant is combining a known look and feel or using a wire-frame to make your demo mean something. Not relevant is spending to much time on this task, **so **back-end functionality (which is being demonstrated) is not complete, which runs the risk of misleading the audience).
