High-density work is not the opposite of good design. A dispatcher, analyst, or care coordinator needs a lot of information in view because the work changes quickly and context switching is costly.
The design problem is therefore not to remove data. It is to establish a stable reading order: primary state first, exceptions second, supporting details available without taking over the screen.
Typography, spacing, and contrast do much of this work. Repeated patterns make important values easy to locate, while quieter surfaces prevent secondary information from competing with urgent tasks.
Density becomes fatiguing when every element asks for equal attention. A system with deliberate hierarchy lets experienced operators move quickly without making new operators feel lost.
