What is a design system?

And why it is more than just a library or a style guide

Let’s start with a story.

Recently, I was talking about design systems infrastructure at the awesome React Finland conference. The day before the conference, there was a traditional dinner for speakers. I like this tradition as it makes possible for us speakers to meet our fellows and the conference organizers so that the next days we work as a team to provide the very best event. As usual, we were asking each other what the talks are about. When it was my turn, I started to explain that my talk is going to be about building infrastructure for a design system and particularly a design system website. One person interrupted me with a question “A style guide?“. And that is the key issue. Many people think that design systems are equal to style guides. But they are much more, they must be much more. On this page, I show what is a design system from different perspectives: design, development, project and even business.

What is a design system for me?

We can have a look at who are the actual or potential users of design systems, and what are their professional needs in this context.

Design systems are often understood as libraries of components. In this regard, the developers are seeing the system mostly from this perspective. Developers would like to have documentation for every component, examples of usage and maybe explanation of the implementation details. Apart from that, they would need information related to the whole system. Such as release notes, instructions for linking the library to the project, etc. For contribution, they need to know what is the library code style and contribution policy. To give feedback, they need the contact information of the design system team and/or access to relevant boards or chats.

Designers also need documentation for every pattern, especially the reasons behind them. Other design-related documentation such as color palette, spacing examples, tone of voice, and many more helps them to create new patterns which are coherent with the rest of the system. They also need information about how to collaborate with other fellow designers and what are the tools to use. Designers are interested in seeing their creations alive, thus they need to know how the process goes further on the development and later stages.

Project managers or owners need to have a basic representation of the design system since this is what is used to build the interface for their product. They are also interested in release notes as in something that has been implemented. Apart from that, managers need to know the design system’s nearest future or, in particular, what new components are going to be released and what are the upcoming changes to the existing ones. For that, managers need to see the design system’s roadmap and learn its strategy as well as be able to discuss this with the relevant people.

On the business levels of the company, especially if speaking about mid-size or large companies, design systems are seen as internal products and tools. People of this specialization need to have a larger scale picture of the system. Also, they must be especially interested into design system’s meta information such as what is its impact, how it helps in-team and cross-team collaboration and maybe even the numbers of how much the company earns and saves thanks to the design system.

Design system — what is behind?

Design systems are yet evolving concept, our understanding of them is changing. But for sure a design system must serve the needs of all the people involved in product creation and managing the company. This brings us to the conclusion that a design system is not equal to a library of components or to a style guide, it is something bigger. From my experience, a functioning and living design system means the following.

Shared practices

A library of components and style guide as their documentation are such shared practices. However, shared practices are not limited to them but also include more abstract or more design related things such as visual language or tone of voice. Or on the contrary, they can be deeply technical and reflect your approach to code (aka code style).

Tools

This brings us to the tools which our company could have for all the developers and designers to share. This means professional software to use and its plugins, scripts for processing and optimizing visuals and code, development and design environment, etc.

Processes

At the next level, design systems would mean the processes which are followed in the company to achieve the outlined goals. Often spoken that design systems bridge the gap between specializations. This means that the design system should establish the processes in teams or even on the company level.

Community

As mentioned above, design systems ensure multidisciplinary collaboration and are meant to help the working collective as a whole. In this regard, having a design system implies constant work with our fellow developers, designers and project owners as with a community.

Way to go

A comprehensive design system would have all the aspects listed above; not only a style guide or a library but documentation and helpful tools for all the practices to follow, outlined and tuned processes for achieving the goals and helping the routines as well as own community-related documentations, instruments, and actions.

Creating and maintaining the design system is not limited to making visual designs and coding but does include service design, project and community management. Moreover, a design system tightly connected to brand and business of the company, so the methods of running it have to be tailored for the specific organization and its teams. These are the topics for many more articles and discussions (yet published Maintaining design systems with proper user research and presented Building design systems that leverage your designers, developers, and products).

Coming back to the story in very beginning, my talk was about documenting all the listed aspects at a company design system website and organizing the processes for its constant evolving: slides, video.
