So you've isolated your five key concepts now you got to divvy up the responsibilities, I would recommend that each person hit no more than one main point. Now if you've got 10 people giving the presentation, you've got two people per point to flesh out different aspects of it or different examples. If you have three people, then two of them hit a couple of points. What you don't want to do is have each person try to cover everything and be duplicative and cover the same topics. And what you don't want to do is have each person try to explain every single part of their little niche their Little Kingdom. So that's what you've got to decide.
Now make assignments, decide who exactly is going to talk about what and let's figure out the order who's going to start off. You want your strongest presenter to start and your strongest are your second strongest to finish. Both are critically important. And let's figure out some orders. Hear so come up with the points, divvy it up, figure out a logical order that makes sense. Do this before starting a single PowerPoint slide.
The worst thing you could possibly do is just start typing slap bullet, bullet, bullet, bullet point bullet. No. Hey, folks, we got 35 slides. Now we got the presentation. Now let's figure out who does what. If you do that approach, you are guaranteed failure.
Start with the messages, figure out the order. Give the assignments we'll worry about the PowerPoint later.
