Design Systems

What is a design system?

A design system is a centralized library of guidelines that helps organizations maintain consistency in the design and development of digital products, experiences, and interfaces.

It includes brand rules, assets, or any other part of a company's brand and serves as a single source of information for designers to streamline design and branding processes.

Types of design systems

Depending on the usage, there are three types of design systems.

• Brand design systems: These systems focus on the visual aspect of an organization’s brand, such as logos, color palettes, and fonts. Brand design systems will include guidelines on using these elements to ensure consistency and compliance.
• UI design systems: These systems focus on the interactive elements of digital interfaces, which include buttons, icons, and navigation menus. Using these systems helps companies ensure consistency in how the interface looks and feels across all its products.
• Accessibility design systems: These systems provide guidelines around accessibility factors, including accessible color contrast, keyboard navigation, and screen reader compatibility. This helps a company make its products accessible to users with disabilities.

Basic elements of a design system

Here are the key elements of a design system:

• Tokens: Tokens are the most fundamental part of a design system used to build more complex elements, such as assets, components, and patterns. Think of them as the atoms used to build more involved molecules. Tokens include color palette, typography, and spacing rules.
• Assets: Assets are one step up from tokens. They are more complex building blocks that have a fixed function. Asset examples are icon libraries and brand assets.
• Components: Components are groups of separate assets built together to serve a specific function and can be reused.
• Patterns: Patterns are built by grouping components and help solve specific design problems.

Benefits of using a design system

Design systems are used by design and development professionals to ensure visual and interactive consistency across products, interfaces, and other visual materials. Here are some of the benefits that they offer:

• Consistency: With brand consistency across all customer touchpoints, design systems help companies boost brand recognition and trust.
• Efficiency: Design systems streamline design and development processes by providing reusable guidelines, components, and patterns.
• Scalability: By standardizing brand identity, these design systems help build a strong foundation for new products.
• Cost saving: Design systems cut costs by reducing duplication of effort, minimizing errors, and saving time.

Design system best practices

A design system is only effective if it is properly managed and implemented. Here are some best practices to follow:

• Documentation: Clear documentation helps users understand how to use the system effectively.
• Modular design: Making sure that the system is organized ensures that it can be updated, customized, and scaled.
• Accessibility: Accessibility guidelines should always be included to ensure that all components are designed to be accessible to all users.
• Training: Training resources should be created and distributed to educate users and promote adoption.

Design system vs. style guide

A design system is a comprehensive set of guidelines, rules, and components that cover a wide range of aspects related to design and development. It provides detailed documentation on how to implement design elements in various situations. 

A style guide is more focused on the visual identity of a brand or product, specifying which logos and fonts to use when creating various materials. Style guides often act as a subset of design systems.
