Understanding Design Systems

A design system is a collection of reusable components, guided by clear standards, that can be assembled to build any number of applications.

Anatomy of a Design System

Design systems connect abstract principles to concrete implementations through a layered architecture

Principles

Core values & philosophy

Design Language

Color, typography, spacing, motion

Components

Buttons, cards, inputs, navigation

Patterns

Forms, authentication, search, navigation

Applications

Websites, mobile apps, products

What is a Design System?

A design system is a complete set of standards, documentation, and principles along with the toolkit (UI patterns and code components) to achieve those standards. It's essentially the source of truth that helps teams design and develop consistent, cohesive products.

Unlike style guides or component libraries, a design system isn't just a collection of UI elements and code snippets. It's a living ecosystem that evolves with your product and provides context for how, when, and why to use each component.

Style Guide

Static documentation of visual elements like colors, typography, and imagery.

Component Library

Collection of reusable UI components with code implementations.

Design System

Complete ecosystem with principles, patterns, components, tools, and governance.
