Today’s design systems are the culmination of decades of experience in building digital products collaboratively. Undeniably, they are becoming the leading paradigm for organizing, evolving, and extending the component libraries underpinning modern apps and platforms. An effective design system unites product teams around a common vision and design language. It represents a trusted Single Source of Truth, provides us with battle-tested, reusable components, and defines the processes and responsibilities governing its ongoing development. It allows engineers and designers to communicate effortlessly and enables them to deliver consistent experiences at any scale. An accessible and well-documented design system also simplifies onboarding processes, as it codifies implicit structures and standardizes workflows. In summary, it’s a game-changing concept that can truly empower digital product teams when implemented properly.
