When you are creating presentations, telling a story is job one. However, it is important to anticipate the questions that can come from your audience. But anticipating questions is only the first step. Next you will want to thoroughly answer the question. Then the key is to create a slide that will address both the question and the answer and put it in the appendix. For each presentation you may want to create 1-5 appendix slides for key potential questions, then not only will you be ready for the presentation but also for the questions that come along with it. This thoroughness and thoughtfulness will help you land your overall presentation points.
