What is design system?

A design system is a library of reusable components and guidelines that people within a company can combine into interfaces and interactions. What goes into a design system and how it is implemented can vary quite a bit from company to company, depending on the size and maturity of the design practice and the needs of the product team.

At their core, design systems provide consistent styling and interaction guidelines for teams. For example, a design system might have:

  • standard elements, like input boxes, dropdown lists, and menu structures, for use in interfaces.
  • a list of approved brand colors and fonts, along with guidance for when to use them.
  • standard buttons and other interactive affordances.
  • interaction guidelines, like whether to use a slide out side panel or to support expanding pinching to resize images.
  • a flexible grid system so that screens are laid out consistently, including things like styling of cards or content separators.
  • rules about the placement of certain objects – for example, always keeping the log in/log out and profile icons in the top-right corner of the desktop.
  • lists of icons and what they mean.
  • content guidelines that specify how and when to use content – for example, whether all menu items should be verbs or nouns or whether the company refers to the user in the first or second person.
  • rules about when to use icons and when to use text as labels.
  • visual guidelines for where certain types of call-to-action buttons should be.
  • rules about whether to use things like auto-save vs explicit save/cancel buttons.

Design systems can also be created for tools that don’t have a visual element to them, such as voice-controlled systems. They would, of course, have a different set of features that were more focused on things like content and behavior, but they can be just as useful.

The most important thing to know about design systems is that the most effective ones continue to grow and change as the needs of a product or suite of products changes. Also, design systems are only effective when their use is mandated.

Ideally, the different elements of a design system are actually pieces of code that developers can drop into interfaces in order to build a feature quicker or prototype faster. Other times, they’re simply design elements in a prototyping tool that designers can reuse.

Advantages of Design Systems

Design systems, when properly implemented, speed up the design process quite a bit. They also make it so that designers and the rest of the product team can focus more on the flow and logic of a new feature or screen rather than the visual design.

It’s not that the visual design isn’t important! It can be. But design systems mean that we don’t have to design each individual element on each screen by hand from scratch. It also means that, when we do come up with a new interface element, it can be shared by the entire design team efficiently.

If used properly, design systems encourage more consistency in our interfaces. Call-to-action buttons are always styled the same way and put in the same place on different screens, so users don’t have to hunt around for things. Menus work consistently, so users don’t get lost. On mobile, the same gestures work the same way from screen to screen.

While you are focusing on the product design business, a design system will consist of the collection of documents, articles, code samples, screenshots, design principles, components, and digital assets. Usually, you will find these online on a public and internal websites.

This system is made up of a number of repetitive, reusable parts as well as instructions on how you can utilize each of those parts. You can need to streamline the design process, deal with design inconsistency, and reduce design entropy using design systems.

Just think of it as a great knowledge library combining a UI kit, documentation, and rules for language and code.

When creating a unified user experience across many products or services, designers often turn to design systems, which are libraries of documents and reusable components. The product’s components, interface, and user flow can all be defined with their help. Color schemes, typefaces, layout grids, icons, and interface elements like buttons, forms, and navigation bars are all part of a comprehensive design system. They are employed to keep items uniform in appearance and operation, hence facilitating a uniform user experience across a wide range of products and mediums.
