Nancy Duarte teaches this and has written several books about it. Here's what she suggests.
Senior executives are one of the toughest crowds you'll face as a presenter. They're incredibly impatient because their schedules are jam-packed. So they won't sit still for a long presentation with a big reveal at the end. They'll just interrupt you before you finish your shtick. So quickly and clearly present information that's important to them, ask for questions, and then be done. If your spiel is short and insightful, you'll get their ear again.
Summarize up front: Say you're given 30 minutes to present. When creating your intro, pretend your whole slot got cut to 5 minutes. This will force you to lead with all the information your audience really cares about — high-level findings, conclusions, recommendations, a call to action. State those points clearly and succinctly right at the start, and then move on to supporting data, subtleties, and material that's peripherally relevant.
Set expectations: Let the audience know you'll spend the first few minutes presenting your summary and the rest of the time on discussion. Even the most impatient executives will be more likely to let you get through your main points uninterrupted if they know they'll soon get to ask questions.
Create summary slides: When making your slide deck, place a short overview of key points at the front; the rest of your slides should serve as an appendix. Follow the 10% rule: If your appendix is 50 slides, create 5 summary slides, and so on. After you present the summary, let the group drive the conversation, and refer to appendix slides as relevant questions and comments come up. Often, executives will want to go deeper into certain points that will aid in their decision making. If they do, quickly pull up the slides that speak to those points.
Give them what they asked for: If you were invited to give an update about the flooding of your company's manufacturing plant in Indonesia, do so before covering anything else. This time-pressed group of senior managers invited you to speak because they felt you could supply a missing piece of information. So answer that specific request directly and quickly.
Rehearse: Before presenting, run your talk and your slides by a colleague who will serve as an honest coach. Try to find someone who's had success getting ideas adopted at the executive level. Ask for pointed feedback: Is your message coming through clearly and quickly? Do your summary slides boil everything down into skimmable key insights? Are you missing anything your audience is likely to expect?My experience in presenting to boards and senior execs confirms Duarte's opinion. Think of these people as the Supreme Court. They're going to control your time. The best-laid plans ...
