2.9 Use a design system for interface consistency

User Experience Design

Keep the components of the project as consistent and clear as possible by using a design system to organize reusable features.

Criteria

  • Design system:
    Use a formal design system when a project is large or has many contributors to improve performance, consistency, and sustainability. Choose a system based on web standards with reusable components and ensure your project only loads the components actually needed on the front end. Whether using a formal design system or not, always follow familiar design patterns and conventions.

Benefits

  • Accessibility
    Using a design system with accessible components will improve access to information for people with disabilities. Building design features that integrate accessibility from the start ensures everyone is always included.
  • Conversion
    Using design systems supports consistent user interfaces. This improves user trust because individuals will recognize familiar components and know how to use them. This can improve conversion rates as it will reduce frustration, abandonment, and possible complaints.
  • Economic
    Using standardized components and avoiding redundancy can reduce development time and the associated costs. Familiarity makes the experience easier for users, reducing bounce rates.
  • Environment
    Building using recognized design components will reduce the amount of time users spend trying to perform a task. The less time users spend achieving their goals, the lower their energy usage and emissions.
  • Performance
    Building design systems using standardized components reduces the need for repeat coding. This reduces developer coding time and can improve performance. Overall, sustainable patterns reduce emissions.
