It is the best practice of presentation design to have one single concept per slide. There are only two exceptions.
The first exception is when you are presenting the relationship between concepts; in this case you are allowed to have more than one concept because you want to show how they relate to each other. However, the single elements, so the single concepts, must be already known or familiar to your audience, they must have been introduced at a previous time.
The second exception has to do with a moment that you are very familiar with: the summary. In this case, you are allowed to provide a list because you are actually summarizing information that your audience already knows.
This is a good time to review your sticky notes and make sure that you have always only one single concept per slide, and if you have created bulleted lists, you have to throw away the list and keep the single concepts each in a separate slide.
Now, look at your sticky notes again, but think of them as talking points this time, and think about the fact that maybe some of these talking points would benefit from not having a slide at all, and you shouldn’t create that slide.
- Keep it simple, just one concept per slide.
- Look at your slides as talking points and see where you need a visual and where you don’t.
