25. To overcome these challenges thousands of companies
are investing in Design Systems.
So how to get your team on-board?

26. Find the 50 shades of grey moments.
Is everyone happy with the speed of dev & code tasks?
“How do we build this?” “It doesn’t match the design?”
…
Then start with a UI inventory!
And do not give up on talking to people everyday.
