Actually. Theatre & Public
Speaking have things in common.
As a presenter you are a performer!
● Tell a story
● Make it personal
● Make big gestures
● Raise your hand, when asking questions
● Tell jokes (you don’t need to be a comedian)
A well prepared presentation; is half of the work!
● Preparation takes a lot of time.
● Whether it’s a slidedeck or story:
○ Think about the flow of your presentation. After All it’s storytelling.
● Do a tech check, before you are speaking
○ Check audio, Screen Resolution, Demos...
● When you don’t know them, don’t assume they know everything.
● Every topic you introduce, needs explanation.
● Introducing new keywords, repeat them.
● Start simple. Slowly go more advanced.
Who is your audience?
“Who does not know what traffic splitting is?”
“Good, then I will skip that!”
● Some people are shy. Some people are just not sure.
● There’s a chance you lost some of the audience already in the beginning
of your presentation.
“Traffic Splitting = Splitting traffic allows you to conduct
A/B testing between your application versions and
provides control over the pace when rolling out
● Instead of spending time in asking your audience, who doesn’t know
this. You could have explained in 2 lines what it actually is.
● People like confirmation. Even if the whole audience knows, they will be
happy that you, as an expert, confirmed it.
● Use Presenter Mode in Google Slides, Powerpoint, Keynote.
● Don’t print whole books on slides.
○ Use short sentences and bullets
○ Pictures say more than words.
● When showing code:
○ Use short sentences
○ Use line numbers
○ Big font-size, system font
○ Font colors (black on white)
● Bring your own gear.
○ Slidedeck, Charger, Clicker, HDMI/VGA adapters, Tethered
● Prepare your demos.
○ Run through it before your session.
● Did you think about a fallback scenario?
○ Often, at conferences internet/network connections are bad/slow.
I love building prototypes
● Showing a prototype / demo, sets the stage
● Product Demo: Your customers can see your product in action
● Building prototypes go beyond “hello-world”
● You can relate with your customer
It’s a prototype!
● People are often shy. Ask again for questions. - followed up by
an awkward pause.
● Repeat the question, so everyone can hear
● Be honest. If you don’t know the answer right away. Let’s talk
● Prepare a question, in case no questions are asked.
“And now it’s time to take some questions...”
● Pick one of the random words:
○ SPORT / VACATION / MY MISTAKE
● Everyone get 10-15min to prepare, a story
● Then each presenter gets 2 min, for their mini presentation.
- WHO YOU ARE
- STORY ABOUT THE RANDOM WORD
- BUILD UP YOUR STORY
- LANDING / CONCLUSION
Let’s prepare panel presentations
