“disrupt”

“disrupt”• don’t “just break stuff”

• don’t “disrupt only to disrupt”

• don’t ignore “helpful”

• don’t disrupt others (most of the time)

“disrupt”

What’s the problem?It’s when we stop learning.

My motivation

It’s a tra

20 CEOs in one Company

• No managers!• Full transparency!• Fully distributed company!• Trust, responsibility & awesome!

That moment when you can!

“Been there, done that”,!

and then compare and learn even more!!

culture differences ( )(don’t generalise, but be aware of it)

Example from my work-life:

very direct!historically cunning!

(because of old. communism gov.)

not direct, it’s being polite!historically peace > personal stuff

And it’s the same with other countries!!Everybody has different “styles” of interaction.!

And software is a lot of human interaction.

Try a “weird” session!

Just do it.

You’ll get a simple “thanks”.!!
