Design KPIs and UX Metrics, with useful examples, resources and articles to measure the impact of design and track it over time — for designers and design teams ↓ Design isn’t art. It solves problems. So we should be able to measure how well a particular design solves a particular problem. Recently, I’ve started working on design KPIs that inform design decisions — here are some examples:
1. Top tasks success rate > 80% (for critical tasks)
2. Time to complete < 35s (for critical tasks)
3. Avg. time to relevance < 30s (for navigation and search)
4. Search results relevance rate > 80% (for top 100 search queries)
5. Search query iterations < 3/query (to avoid dead-ends)
6. Relevance of top 100 search requests > 80% (search quality)
7. Average frequency of errors < 3/visit (mistaps, double clicks)
8. Error recovery speed < 7s (effectiveness of error messages)
9. Accuracy of sent data ≈ 100% (input by customers in forms)
10. Sales/marketing costs < $15K/week (poor design -> increased costs)
11. Time to first success < 15 sec (onboarding)
12. Service desk inquiries < 35/week (poor design -> more inquiries)
13. Service desk response time < 12h (speed of processing)
14. Customers follow-up rate < 4% (quality of service desk replies)
15. “Turn-around” score < 1 week (frustrated users -> happy users)
16. Environmental impact < 0.3g/page request (sustainability)
17. Flesch reading ease score > 60 (quality of text/copywriting)
18. System Usability Scale > 75 (overall usability)
19. WCAG AA coverage ≈ 100% (accessibility)
20. Core Web Vitals ≈ 100% (performance)
For a given project, around 3–4 KPIs will be most critical, and there will be around 4–5 further KPIs being measured over time — once every 4–6 months, along with user interviews designed to test how well and how fast users complete their tasks. It’s worth noting that every team usually has their own tailored set of custom KPIs. The success of each team is then assessed by how well they are performing across their own KPIs.
