How To Evaluate Your Design System UX Agency?
During our benchmarking, we identified three key issues that often arise while choosing a design system UX agency:
Most agencies don’t understand how tokens, component libraries, and developer needs tie together
The design system isn’t scalable or well-documented across web and mobile
There’s poor collaboration with engineering—no proper handoff, accessibility specs, or dev integration
