Branding is a beast. If you’re not careful, brands can become unwieldy and disconnected over time. A good design system prevents that breakdown and helps anyone in the company effectively communicate the brand.
Alla does an excellent job giving tangible examples from companies like AirBnb, Atlassian and other prominent brands. This book serves as a guide for anyone looking to build a design system from scratch or improve their current design system. Needless to say, this book is well worth the time and money if you need to have a solid framework for UI and Interaction design.
