# Living system

## What is a living design system?

Eufemia, DNB's design system, is a UI collection of components, rules, principles, constraints, and best practices for UI design and front-end code, and is subject to continuous improvement over time.

### In a practical manner

Many developers think of a design system as a pattern library; however, it is important to remember that Eufemia is a living design system. Suggestions, improvements, new integrations and new additions to the system will continuously shape Eufemia.

## Consistency

One of the main goals for Eufemia is to give the user consistency during the user journey.
Consistency will be experienced in many ways, like consistent extensions, state interactions, navigation logic, color usage and accessibility.

## Single source of truth

A design system like Eufemia is the single source of truth for UI assets and components. This includes ready-to-use UI elements in code for developers and graphic libraries for UX-designers.

## Knowledge pool

We at DNB UX embrace the DNB core vision and main goals: _Do less, do better_ and _Increase user experience_. To meet these goals, Eufemia has as a core value to increase knowledge of front-end development, UX design, and accessibility. This means that Eufemia will always be under continuous improvement and QA.
