## Summary
Relevance is the quality or state of being significantly related to or appropriate for a given task, context, or user need. In [[System|system]] design, relevance refers to how well a system's outputs, features, and [[Information|information]] align with user requirements and expectations. Relevant systems provide information and capabilities that matter to users, avoiding unnecessary noise or distraction. Relevance is a key aspect of information quality, system [[Usability|usability]], and overall effectiveness in meeting user goals.
## Key points
- Alignment of system outputs and features with user needs
- Quality of being significantly related to task or context
- Provides information and capabilities that matter to users
- Aspect of information quality and system effectiveness
## Relation to System Quality Attributes
This article connects to system quality attributes as relevance directly influences how systems are designed, evaluated, and operated. It contributes to understanding the broader [[Ecosystem|ecosystem]] of quality concerns, from high-level requirements and [[Architecture|architecture]] patterns down to specific measurable attributes and [[Engineering|engineering]] practices.
