The key to creating a well-organized speech or presentation is to keep your audience in mind. Start with something that will capture their attention and give them a clear idea of your topic.
Organise the body of your presentation in a way that will be easy for your audience to understand. Plan to review your main points briefly and then wrap things up on a positive note, perhaps giving your audience a “call to action.”
The essential thing to remember is that you are giving your presentation for the benefit of your audience. That means you need to organise it in a way that will make sense to them. The most important thing to keep in the forefront of your mind is that you are not making the speech for yourself, but your audience.
Think of how politicians do things. When they are campaigning they will speak to groups as diverse as different occupations, different ethnicities, and different ages. How they will speak to each changes between speeches. Then, when they are speaking to a cabinet meeting of fellow politicians, the language and the issues will be different again. Keep this in mind when giving a presentation.
