A design system is:

• a collection of reusable components with clear standards that can be assembled together to build any number of applications.

A design system enables teams to build:

• better products,
• faster.

A design system is:

• consistent : components are built and managed by a predictable pattern.
• self-contained : is treated as a standalone dependency.
• reusable : components can be reused in many contexts.
• accessible : components follow theWeb Content Accessibility Guidelines, which means the app caters for all users (regardless devices used or personal disabilities).
