Recognizing the Key Components

Each part of a design system has its own purpose, yet all of them contribute to making design and development faster, clearer, and more consistent:

• Design Principles: The high-level values and philosophy that guide trade-offs and decision-making.
• Component & Pattern Libraries: Components are individual reusable UI widgets (buttons, input fields), while patterns describe how these elements combine into coherent layouts, navigation structures, and user workflows.
• Visual & Conceptual Foundations: The atomic base of the system—colors, typography, spacing, border radii, iconography, and state transitions (hover, pressed, focus, disabled).
• Design Tokens: Platform-agnostic variables that capture visual decisions in a shared, structured format (JSON) compiling to CSS, Swift, and XML.
• Documentation & Governance: Explicit usage rules, accessibility criteria, and change management workflows.
