Case studies or examples are a great way to explain your idea or technology. And by case study I mean something different than the empty, generic, meaningless quotes you find in many technology white papers. We need real stories.

Wherever possible, I try to stick to one big case study throughout the presentation, avoiding many smaller case studies. I can use this one case study to highlight different aspects of the technology.

• It saves time, I do not have to introduce a new story setting all the time
• It saves time, because I can re-use visual concepts. (For example, the red stars are the dangerous computer viruses)
• I can afford to take a really detailed deep dive if needed
• In case of complex science (healthcare technology for example) I can afford to take the time to introduce a few advanced scientific concepts and use them throughout my presentation
• Images and visuals will look consistent throughout the presentation

The key challenge in these type of presentations is not so much the visual design, it is finding that case study that says it all. And once you are thinking about that, you are actually trying to find your story,
