System Design Principles
Pareto Principle
Roughly 80% of outcomes come from 20% of causes.
Takeaways
- 1
Identify the few actions that drive most user value.
- 2
Design dashboards around actionable metrics, not everything available.
- 3
Optimize high-traffic flows before edge cases.
Origins
The Pareto principle is a prioritization lens: a small set of inputs often produces most results. In UX, that means a handful of flows, features, or screens account for the majority of success and frustration.
Design resources go further when aimed at those leverage points.
Design Applications
- Make the top user journey frictionless before expanding scope.
- Highlight the metrics users can act on immediately.
- Defer rarely used settings to secondary surfaces.
