The sketching process helps you clarify what you want to say and how you want to say it. As Dan Roam, author of The Back of the Napkin, points out, “All the real problems of today are multidimensional…There is no way to fully understand them—thus no way to effectively begin solving them—without at some point literally drawing them out.”
As you storyboard your presentation, you’ll be able to tell immediately which concepts are clunky or overly complex—they’ll be the ones that you just can’t seem to fit on a sticky note. Eliminate them, and brainstorm new ways to communicate those messages.
There’s a good chance you’ll be able to develop at least a couple of your storyboarding doodles into graphics or diagrams that you’ll actually use in the presentation. If they’ll help the audience understand or remember your verbal message, they’re worth including. But even if you don’t display any images when you present, nice big type on the screen is better than dense prose.
