The Outline Slide
The Outline Slide is a staple in scientific presentations.

The Outline Slide presents the audience with the path that your presentation will follow. The slide provides the first step in a three pronged approach of giving a presentation, “say what you are going to say, say it and say what you’ve said.” This approach reinforces the main points of the presentation to your audience.
How about instead just “say it.”
How about get to the point, tell your story, people don’t leave presentations saying, “great talk, wish it was longer.”
If you are worried that by not giving an Outline Slide that your talk will be hard to follow, you are probably right. However, the Outline Slide isn’t the problem, it is the rest of your talk.
