@emmawedekind

Systems are in the world all around us.

Our products are no exception.

@emmawedekind

The Internet was not originally built for large-scale social and enterprise applications.

Webpages

Bookmarking

Pagination

@emmawedekind

We don't develop websites as full pages anymore.

@emmawedekind

Webpages !== Reusability

@emmawedekind

Components === Reusability

@emmawedekind

@emmawedekind

The way in which we design and develop products is shifting to components.

@emmawedekind

We all think about the world in different ways...

inconsistent user interfaces.

and this leads to

Design systems fail from a lack of team buy-in.

@emmawedekind

Centralized model

The design system is governed by a centralized, core team.

@emmawedekind

  • Define the foundation & identity of the design system

  • Have veto power over the system

  • Manage & create the UI kit, component library, & style guide

@emmawedekind

@emmawedekind

@emmawedekind

Distributed model

The design system is built and maintained by those using it.

@emmawedekind

  • Empowers individuals to make decisions

  • Design decisions aren't concentrated; they're influenced by many vantage points

  • Progress isn't hindered if someone is unavailable

@emmawedekind

@emmawedekind

@emmawedekind

Hybrid model

Combines the centralized and distributed models.

@emmawedekind

@emmawedekind

@emmawedekind

Design systems aren't necessarily meant for you.

@emmawedekind

"If a design system is by a company, then it's for the company. It might also be open source, but any ol' random developer who wants to use it isn't the target audience."
