I've fought the good fight against bad Power Point (PP) for some time now, and the forces amassed against the Microsoft Juggernaut have made some headway at the level of the debate, but not much at the practical level.  There's still a whole lot of bad PP going on. 

Let's get some things clear.  First of all, bad PP NEVER helps a speech — whether it's a presentation to a team, or a keynote, or a Senator's filibuster.  All bad PP does is document the horror.  What do I mean by bad PP?  Anything that involves more words than pictures.  Those are speaker notes, and they should not be shown to the audience.  I gave a speech this week, and there was one speech before mine at the event.  That speaker included two columns of bullets on one slide, which he introduced by saying, "You probably can't read this, but…."  Please!

Second, PP rarely improves a bad speech.  A bad speech is just that, bad.  Whether it's because the speaker hasn't adequately prepared, and rambles, or the non-verbal conversation is at war with the verbal, or the topic is not right for the audience — there are a million possible ways a speech can go wrong – when it's bad, it's bad.  Of course, PP gives you something to look at if your mind is wandering, but that's like starting to study the scenery in a bad movie — you're still not having a good time.  Worse than that, your time is being wasted.

Third, good PP (see Presentation Zen, which I've recommended before) CAN add to a good speech, under certain conditions.  First of all, the PP has to do something that the words can't do.  So, a great picture can bring something to life in a way that it takes too many words to do.  A bit of video can add emotion and context, and put you in a place that words can't do so easily.  And so on.

But, NEVER use even good PP as wallpaper, especially for a speech, such as a keynote, when inspiration is supposed to be part of the deal.  Here's what happens:  you're asking the audience to multitask, and the studies show that multitasking makes us STUPID.  So don't do it.  Of course, we're used to multitasking, and having lots of distractions, and some people think they're not being fully utilized, or pampered, unless all that's going on, but a GOOD SPEECH holds an audience WITHOUT the need for PP. 

Bottom line:  use PP with care, make it about pictures, and focus on getting the speech right first.  If people need PP to get through your speech, there's something wrong with the speech.
