In the last section we looked at Black Boxes as a tactic – a related idea is:
Chapters in a novel

Consider how much harder it would be to read a novel without chapters: it’s almost unthinkable that an author would just write page after page of text. Chapters have a number of functions – such as giving you sensible places to stop reading and go to sleep if you’re reading in bed! – including signalling to the reader that: this is the end of a ‘thought’.
When the action starts again in the next chapter something will have changed. This might be which characters are involved, location, time or just the emotions of the people mentioned; but something has changed.

Using Black Boxes your presentation should be structured in a way which is analogous.
At the end of a chapter in a novel there is often a white page, followed by a chapter title (or at least a number). How can you emulate that in your presentation? It really couldn’t be more simple. Consider using a sequence of:
- a summary slide at the end of your black box to state the key point (random data in, sorted data out)
- a black slide to allow the audience to get the idea you’re starting afresh
- a title slide for your next section.
Yes, it’s a little formulaic, but you can start being more creative later, once you’ve mastered the basics!
Getting more creative Black boxes can be signalled in other ways to the formula of slides above. It’s largely a combination of your imagination and the logistics of the room you’re working in that dictate/limit what you can do, but examples that often work well include… |

- swapping speaker – if you’re doing a tag-team presentation
- changing medium – move from slides to flipchart etc.changing layout – if you stick with slides make your new slides with a different feel/layout… if it’s a report, consider something like changing the layout of the page by using columns or landscape layout
- changing your position – use the black slide as an opportunity to move from one side of the screen to the othera combination of these – and the formula above, all at once.
