When you are brainstorming about the topics to present during your presentation it is important to also consider the right flow of your presentation.
In general there are 3 sections of each successful presentation:
1) Introduction: Tell them what you are going to tell them
2) Content: Tell them
3) Conclusion: Tell them what you told them
The topics within each section need to be in a logical order that is easy to follow for your audience. Especially when you practice your presentation, you can relatively easily identify if the flow of your presentation is correct. Changing order, skipping and/or adding topics may assist to ensure the best flow of your presentation.
