Follow the Rule of 10
Guy Kawasaki — former Apple "chief evangelist," venture capitalist and professional speaking guru — has established his famous "Kawasaki Rule of Ten" in which he only uses 10 slides during a PowerPoint presentation, often in a top 10 fashion. Those slides generally consist of nothing more than a single sentence or phrase and a supporting image. All 10 give the audience powerful visual cues that reinforce the message that Kawasaki is communicating. And since audience members know that there are only going to be 10 slides, they know when the presentation is about to end.
Kawasaki suggests a steady narrative stream for these 10 slides. Starting, for example, with the problem on slide No. 1 and the solution on slide No. 2, all the way down to the timeline on No. 9 and the summarizing call to action on slide No. 10 [source: Kawasaki].
So how long does Kawasaki recommend these PowerPoint shindigs usually last? We'll tell you next.
