> Make your presentations zing. A presentation is not facts, it's an interpretation of facts. Your job as a presenter is to advise and guide your audience. > Communicate knowledge to an audience at any level. A presentation fits into a wider communication chain. Understanding this will help you to figure out what works in a presentation ? stories, images, videos, examples, analogies, demonstrations, interaction ? and, crucially, what should be left out. > Make your presentation audience-centred not presenter-centred. Don't define your presentation based what you know but rather on what the audience needs to hear. > Connect with your audience. Content is the dominant factor in a presentation, not delivery. You already know how to deliver; you do it every time you open your mouth. The key is to tap into this conversational energy and fluency. > Embrace PowerPoint to make your presentations first class.
