Joey shares insights on tackling variable structure in design systems, an area that often overwhelms teams. The pressure to create a solid foundation that accommodates all potential use cases can freeze progress. Variables in Figma are meant to simplify design by allowing teams to define and reuse shared values like colors and spacing, rather than hard-coding them. The challenge lies in understanding how to structure these variables effectively. A practical solution Joey suggests is to categorize variables into non-interactive and interactive groups. Non-interactive variables define the static elements of a design, such as background colors and borders. Interactive variables, on the other hand, relate to user input and behavior, including button states like hover and press. This clear separation helps teams quickly grasp the intent behind design elements, making it easier to implement and scale their work. Joey emphasizes that clarity is more important than perfection when starting out, allowing teams to establish a useful foundation for their design systems.
