Because it is applicable to practically any topic or kind of speech, a topical pattern is the most frequent approach to arrange talks, particularly informational addresses. A topical structure entails breaking down your principal notion into subject categories or sub-topics that surround it. These subjects can be arranged in any order you choose so long as they are all included. For example, if your talk concerns the Civil War, you could divide it into three separate subjects: Lincoln, Jefferson Davis, and Women in the Civil War. Each subject would constitute a sub-topic which could then be further divided into relevant topics within that subject. For instance, under Lincoln you could discuss leaders before and after him, battles he was involved in, etc. The only restriction here is that none of these sub-topics can be longer than about five minutes each or the audience will lose interest. A variation on the topical structure is the panel discussion. Here again you break down your idea into different subjects, but this time each speaker gives a short presentation on one issue, which are then followed by questions from the audience. For example, six people attend your conference. You split them into three panels of two people each. Your first panel discusses problems with social media used by businesses, the second one describes best practices when it comes to privacy issues, while the third one examines legal aspects of online marketing.
