Edward Tufte has suggestions on how to give good technical presentations

If you don’t know who Edward Tufte is, then you really should. He is a Professor Emeritus at Yale University and his specialty is teaching people how to present data using information graphics. He is truly an expert on the best way to present complex information. A long time I was scanning the web when I ran across some notes that Craig Kaplan up at the University of Waterloo had jotted down on how to deliver great presentations after attending one of Tufte’s seminars. We’ve already talked about how to write a great presentation. I now share these suggestions on how to give a good presentation with the reverence that one must show to the words of someone who is really, really good at what they do:

  • Show Up Early!: Good things happen to those who show up early. Specifically, you can solve problems before they become unsolvable and you can take the time to introduce yourself to the audience as they arrive. This way when you start to speak neither one of you will be a stranger.

  • Have A Strong Opening: There are three questions that every opening must quickly answer: (1) What’s the problem?, (2) Who cares?, and (3) What’s your solution? Answer these questions and the audience will listen to your every word.
  • PGP: As you introduce a new sub-topic, make sure that you move from the particular, to the general, and then back to the particular. Although what you want the audience to take away from your presentation is the general info, the particulars will help make the info “stick”.
  • Know Your Audience — By What They Read!: This is Tufte’s twist on an old maxim of public speaking. He believes that knowing what your audience reads will help you understand what styles of information presentation works best for them.
  • Take Care When Answering Questions: There is a good possibility that your audience’s take-away impression of your presentation won’t be based on your presentation, but rather on how you answer questions AFTER the presentation. Allow for long pauses after the question has been asked and before you answer — this will give more weight to your reply.
  • Let Everyone Know That You Belive In Your Material: Speak with lots of convection! Clearly letting everyone know that you believe in everything that you are telling them is the key to getting them to believe it just as much as you do.

There you have it. Now please remember that Tufte also has the ability to use amazing graphics with his presentations that clearly communicate what lots of data has to say. However, even the best graphics won’t do you any good if you don’t remember these presenting rules from the master.

Get ‘Em To Understand, Get ‘Em To Remember

Hard To Get Adults To Remember Speech Contents
Sigh, so you’ve spent all that time collecting your information, writing the report, making the slides and even created a great handout. Now how much of your presentation do you really think that your audience will remember 30 minutes after you are done, 1 hour later, 1 day later, how about at the end of a month? Getting our information to first be understood by our audience is one way to be a successful communicator. The other skill that you must have is finding a way to get your message(s) to stick in your audience’s memory.

To promote understanding of your message, remember that people DO judge a book by its cover. In technical presentations this means that your audience will assume that if you have more of something in a figure, then the quantity of that thing is greater. Think about if you were trying to present plans for a new airplane and were trying to communicate how far it could fly. If you decided to show this by showing circles that showed how much fuel was required to fly a given distance. The circle for existing planes would be larger than the circle for your new plane. Although you are trying to communicate that your new plane can fly further, your figure is making it hard for your audience to understand this point.

We communicate information by changing things. As we move from one diagram or graph to the next if we’ve changed something, then our audience expects that that change really means something and we’re trying to tell them something. This also means that if you want to communicate to your audience that there is a change in meaning, then you must make a change in the appearance of your figure / graph.

Ok, last point to be made: just like this blog posting, everyone has a limit to the amount of new information that they can take in. If you overload them with information, then they will not understand the message that you are trying to communicate. If you have a lot of information to present, then you can communicate it if, and only if, you present it piece by piece so that your audience can absorb it little by little.

Whew, all this might be too much for one post; however, I though that it was important and so there you go.
