One of the key things you have to do when giving a group presentation is let other people talk. No, you can’t just hog the stage all to yourself. And you need to practice handing off the presentation to the next speaker because if you mess this part up, it will make your whole presentation look as if you were unprepared. Seriously.
Think about it… It’s like a chef at a restaurant who prepares a beautiful meal, but then she throws it like a frisbee to the server. It’s not going to be pretty.
And it won’t be pretty for your group presentation if the transition between speakers isn’t practiced and done without mistakes.
It’s not a hard thing to do, so check out the video to learn what to say and then go and practice it. No frisbees, please.
