He has an interesting definition of two styles of presentations and when to use each style:
- Ballroom style presentations are what most typical PowerPoint presentations are trying to be: colorful, vibrant, attention-grabbing, and (sometimes) noisy. They typically take place in a large, dark room—such as a hotel ballroom.
- Conference room style presentations are more understated: they have less color, with more details on each page; they are more likely to be on printed handouts than projected slides, and they are more suited to your average corporate conference room.
The biggest single mistake that presenters make—and the root cause of the PowerPoint debate—is confusing the two idioms, and particularly, using ballroom style where conference room style is more appropriate. Almost all PowerPoint presentations are given using ballroom style—yet most of the time presentation conditions call for conference room style. Ballroom style is appropriate for where the objective is to inform, impress, and/or entertain a large audience and where the information flow is largely expected to be one-way (presenter to audience). Conference room style presentations are more suited to meetings where the objective is to engage, persuade, come to some conclusion, and drive action. This covers any presentation where you want your audience to do something differently as a result of your presentation. It includes: making recommendations; selling; training; communicating the implications of research; and raising funds. Information flow in this idiom is expected to be two-way—it’s more interactive.
