Summary: Remove unnecessary elements from the user interface to maximize the signal-to-noise ratio of the design. What's the signal-to-noise ratio? All relevant information is 'signal,' while irrelevant one is 'noise'. A high signal–to–noise ratio is a key goal for any UX professional work (it goes both for content and page design).
Interfaces with high signal–to–noise ratios improve communication with users and make their tasks easier. Strive to reduce the noise and make the signal stand out. Balance organisational priorities and goals. In this way, users are likely to find the information they need easily and complete their tasks.
