Once you know who will be present at your speech, you should try do some additional research to try to determine how they will respond. For instance, if you’re planning to include some controversial suggestions about what you believe the business should do, you might want to first consider raising the topic with co-workers and with your boss, so that you can get feedback before you include them.
Furthermore, if you believe your boss’s boss will be present at the meeting, you may want to spend some extra time with your boss to make sure that your presentation will make him or her look good. If you don’t have much contact with his or her superiors, you might not know exactly how to do this. For this reason, it is a good idea to try to work this out with your boss in advance.
