You are never just presenting information, You want your audience to take some sort of action based on the information. What action do you want them to do or change?
If you ask your audience for an action, have them write it down. It will be remembered 40% more often and it will raise accountability. People remember 3 to 7 things at the most, 3 to 5 is the easiest to recall. Keep your presentation to 3 to 5 Key Points. No more. If your listeners can recall what you said, the likelihood of them taking action increases dramatically.
