What Is a Design System?
A Design System is a dynamic framework that serves as the backbone for design and development of a digital product. It creates a unified language and visual coherence within a product or across multiple products, making it faster and easier to scale and evolve a digital ecosystem that looks and feels consistent and harmonious.
A Design System has two main parts

Component Library
Think of it as a catalog of pre-designed elements — buttons, headlines, dialog boxes, headers, footers, patterns, and more — that can be reused across various screens and platforms.

Documentation
Accompanying the components is a set of guidelines detailing how and when to use each element, ensuring consistency across teams and reducing design debt.
