Remember your target? i.e. The specific thing you want your audience to DO as a result of your presentation.
At the end of the presentation you need to make this crystal clear, in the form of an explicit call to action. Don’t assume the audience knows what you want, or will do it without prompting. The clearer and stronger your call to action, the more chance you have of getting them to do it!
Call to Action
Do you want them to change their minds?
Do you want them to do something?
Make sure you tell them exactly what you want them to do – several times and especially at the end!
