See the tangible difference a design system makes in actual projects
Compare your metrics against typical design system maturity levels
| Metric | Starter | Growing | Mature | World-Class |
|---|---|---|---|---|
| Team Adoption Rate | 40-60% | 60-80% | 80-95% | 95%+ |
| Mature systems see 80%+ adoption within 18 months | ||||
| Time to First Use | 2-3 weeks | 1 week | 3-5 days | Same day |
| Good onboarding gets teams productive in under a week | ||||
| Component Reuse | 30-50% | 50-70% | 70-85% | 85%+ |
| 70%+ reuse indicates strong system coverage | ||||
| User Satisfaction | 3.5-4.0/5 | 4.0-4.3/5 | 4.3-4.7/5 | 4.7+/5 |
| Above 4.5/5 shows excellent system quality and support | ||||
| Delivery Speed Gain | 10-15% | 15-25% | 25-35% | 35%+ |
| Well-adopted systems typically show 20-30% faster delivery | ||||

Different audiences need different information at different frequencies. Tailor your reporting accordingly.
Audience: Design System Team
Audience: Product Teams
Audience: Leadership
Audience: Organization
A well-designed dashboard tells the story of your design system's impact at a glance.
Clear next steps to start measuring today and build momentum over time
Vanity metrics: Focus on metrics that drive decisions, not just impressive numbers.
Over-measurement: Too many metrics can overwhelm and distract from what matters.
Ignoring context: Always consider external factors that might influence your metrics.
