Pretend you have all your content in front of you. Anyone can arrange the points in order of importance or chronologically. But I recommend starting with this question: What does your presentation need to accomplish? Most answers will fit into one of these categories:
Awareness — introducing or educating an audience on a topic.
Attitude — promoting a change or reinforcing your subject.
Action — persuading an audience to act.
With an objective in mind, you can decide what content to include and what information to leave out. By working backward — from the big picture to the small details — you'll save time and produce a more powerful presentation."
