Why not just put up some slides and talk the audience through them?
Presenting a coherent story ensures that you have thought through your ideas before you walk into the room to make your presentation. The act of creating the logical storyline also helps you think through your real purpose – the question – and what you want to walk away from the meeting with. Putting the time in up-front to prepare the story will make you not only more efficient overall, but more effective.
It also makes it much easier for your audience to follow you.
