PowerPoint pedagogy
PowerPoint is not a good way to make a sale or to make a decision. It’s not. Really.
Evidence the continual attempts to squeeze this round peg. Lately, Guy Kawasaki lays down some rules about giving a PP pitch to venture capitalists. His basic advice (10 slides, 20 minutes, 30 pitch font) isn’t bad; the underlying premise is. The best way to convince someone to give you their money is tell a compelling story.
And you can do that without any slides at all.
If you must provide something for people to look at, hand out a single sheet of paper with the important information you want them to remember. Your name, contact information, salient points. Send it to them ahead of the brief, so they can be ready for questions. Okay, maybe the head folks won’t read it, but their staff will. Then use all of your one hour meeting to have a discussion.
