Design system is the "single source of truth" for design and development. Components, standards, guidelines, everything documented. This guide introduces you to how to create and maintain design systems.
What is Design System
Definition
Set of reusable patterns for building products.
Components
UI components, tokens, patterns, guidelines.
Purpose
Consistency, efficiency, scale.
Why Have a Design System
Consistency
Uniform experience across every product.
Speed
Don't reinvent the wheel.
Quality
Tested and approved components.
Scale
Large teams work in alignment.
Maintenance
Update once, propagates to everyone.
Components
Design Tokens
Primitive values: colors, typography, spacing.
UI Components
Buttons, inputs, cards, modals.
###Patterns
Solutions for recurring problems.
Templates
Page layouts.
Design Tokens
What are they
Variables for design values.
Types
Colors, typography, spacing, shadows.
Naming
Semantic: --color-primary vs --color-blue.
Tooling
Style Dictionary, Tokens Studio.
UI Components
Anatomy
Structure, variants, states.
States
Default, hover, active, disabled, error.
Variants
Sizes, styles, contexts.
Composition
Simple components make up complex ones.
Documentation
What to Document
Usage, anatomy, do's and don'ts.
For Whom
Designers and developers.
Format
Dedicated website: Storybook, Docusaurus.
Examples
Code and visual.
Tooling
Design
Figma, Sketch with components.
Development
Component libraries: React, Vue, etc.
Documentation
Storybook, ZeroHeight.
Tokens
Style Dictionary, Tokens Studio.
Figma for Design System
###Components
Reusable master components.
Variants
States and variations.
Auto Layout
Responsive components.
Tokens Studio
Sync tokens.
Libraries
Publish and share.
ComponentLibrary
###Framework
React, Vue, Web Components.
Structure
Isolated, tested components.
Props
Clear and consistent API.
Theming
Customization by project.
###Package
Publish as npm package.
Creation Process
Inventory
Audit existing UI.
Abstraction
Identify common patterns.
Design
Create components in Figma.
Development
Implement in code.
Documentation
Write guidelines.
Launch
Publish and communicate.
Governance
Ownership
Who maintains the system.
Contribution
How teams can contribute.
Versioning
Semantic versioning for components.
Changelog
Communicate changes.
Adoption
Onboarding
Train teams.
###Champions
Promoters on each team.
###Feedback
Collect and incorporate.
Metrics
Mid adoption.
Evolution
Feedback Loop
Learn by use.
Iteration
Continuously improve.
Breaking Changes
Communicate and version.
Deprecation
Retire old components.
Common Errors
Too Soon
Create before you have clear standards.
Very Rigid
Do not allow necessary customization.
Abandoned
Create and not maintain.
Misaligned
Different design and code.
Not Documented
Components without instructions for use.
Examples of Design Systems
Material Design
Google. Public, comprehensive.
Apple Human Interface
iOS, macOS guidelines.
Carbon
IBM. Open source.

Conclusion
Design system is an investment that pays dividends in consistency and speed. Start small, document well and evolve with use. The result is more cohesive products and more productive teams.

3) Do I need a dedicated team? Ideally. But you can start part-time.
4) Public or internal design system? It depends on the context. Many are internal.
5) How to measure success? Adoption, design/dev efficiency, visual consistency.
