How is the Pareto Principle used when designing interfaces?

In the field of user interface (UI) design, the Pareto Principle can be applied to prioritize the most important elements and features of a product or website. By focusing on the 20% of elements that are most critical to the user experience, UI designers can create an interface that is efficient and effective. The Pareto Principle can also be used to identify areas for improvement in the UI by identifying the 20% of elements that are causing the majority of problems or causing the most friction for users.
