Short answer
Measure the percentage of production code components derived from the system versus custom components, and calculate faster feature delivery and fewer design defects and rework.
Explanation
Design System KPIs include: (1) Figma and code component coverage; (2) use of Design Tokens in code; (3) time to market for new features compared with before the system; and (4) work hours saved, calculated by multiplying the number of designers and developers by monthly hours saved, demonstrating direct financial value to management.
Common mistakes
- Measuring Design System success by the number of components published in Figma instead of their actual use in production.
- Ignoring surveys of designers' and developers' satisfaction and responsiveness to regular system updates.
