Law of Audience Ignorance Someone important in the audience always knows less than you think that Who are they? everyone should know. Why are they here? What do they need to learn from you? The audience always wants to know“What’s in it for me?” How much background do they have? What do they expect to get? You must address audience objectives or the talk will fail. What questions might they ask? What will they learn from other presenters?

Set up At the start: The Introduction The most memorable parts are beginning and end; make them work for you. Announce your topic clearly and state objective Introductions can benefit from: Using an outline of the talk is often recommended, but I don’t do it.
