A design system defines the foundational elements, structures, and patterns we want to reuse in our designs. They can be individual elements, like icons or buttons; or a collection of elements, like menus and layouts and are often referred to as ‘atomic’ design. I have played a role as a user, as a contributor, as a builder and as a leader in creating a design system. I offer two examples of work I have done for different design system and what I had hope to accomplish.
