How to avoid “Death by PowerPoint”.
PowerPoint presentations should resemble large posters rather than book pages or have you ever seen a good poster consisting of only headline, subline and ten bulletpoints? In reverse, this means lots of pictures, little text and some entertainment. Forget rules like 1-7-7: Only one argument; maximum seven lines; no more than seven words per line. Or the 10/20/30 rule: A maximum of 10 slides in 20 minutes with a step size of 30 points. A good description of the 10/20/30 rule can be found here. (http://www.startwerk.ch/2010/06/02/die-102030-regel-tipps-fuer-praesentationen-und-pitches/#comment-476870).
If you are not creating a “Pitch Deck”, you should ignore such rigid defaults. It is better to use single-line headings. Reduce the amount of text and spread it over many slides according to “only one argument or message per slide”. Tell details and distribute them later as part of the handouts.
You will find many good examples of this approach in our portfolio.
Everything you can write or sketch with a thick marker (Edding) on a Post-It, comes on the slide. The rest goes into the handouts.
