A design system is a complete set of standards intended to manage design at scale using reusable components and patterns.
Design (and development) work can be created and replicated quickly and at scale.
It alleviates strain on design resources to focus on larger, more complex problems.
It creates a unified language within and between crossfunctional teams.
It creates visual consistency across products, channels, and (potentially siloed) departments.
It can serve as an educational tool and reference for junior-level designers and content contributors.
