Sometimes you only have one day to work on a presentation. Maybe your boss came in the morning and asked you to do a short presentation tomorrow at noon? Well, if you only have one day to work on it, I'll admit, it's a challenge to create a great presentation, but it's not impossible. The first thing you need to do is prioritize the preparation time. Where do you want to invest the time to create the presentation? Under such short time pressure I would suggest using three steps:
- Idea gathering/Brainstorming
- Structuring/Creating the story + Handout
- Slide Design.
Step 2 Structuring/Creating the storyThis Is a crucial step, because once you have all the ideas gathered, you want to structure it into a nice story. Identify what the most important themes and points are. Figure out what your one core message is going to be (e.g. "If we acquire that company, our innovation potential will increase dramatically." or "Using this software will make us 30% more productive!"). Once you've got that figured out, always keep it in the back of your mind, because later - when creating the slides - you should always review: "Does this slide contribute to the core message and the story?" Once you have a good storyline (e.g. one interesting method is to do a storyboard like animation designers do) and you are sure what your one core message is, then invest 20-40 minutes in creating a one-page handout for the listener. This should consist of the main points that you will talk about, it should include possible references and also links to further reading; and also (except it's an internal workshop at work) don't forget to include your contact details in case someone has more questions much later after the presentation (e.g. a week or a month later).
Step 3: Slide DesignThis should be the last step when you're under such time pressure. In the end, if you already have your ideas gathered and the story in place, you don't really need the slides. The slides are there to provide visual aids for the audience. So keep this in mind when creating them. Why not just use full-sized pictures instead of a lot of text? If you're doing a technical presentation, why not put in big images of the technical devices you are talking about? If you work a lot with charts, just put in the charts - do you really need full sentences on the slides? Just explain the charts while you show them, no need for textual explanations on the slides itself. That's a quick rundown of how I would work on the presentation. Good luck with your future presentations!
