Ydeevnekrav

Ydeevnekrav, a Norwegian term that translates to “performance requirements,” are non-functional requirements that specify how well a system, product, or service should perform under defined conditions. They describe the quality of performance rather than the specific functions the system must perform, and are commonly used in software development, IT infrastructure, electronics, and procurement.

Scope and usage: Ydeevnekrav accompany functional requirements in technical specifications and contracts. They guide design decisions,

Specification and validation: Ydeevnekrav are expressed as concrete targets with metrics and thresholds. Examples include time-based

Relation to standards: They align with quality models such as ISO/IEC 25010, where performance efficiency covers

Examples: For a web service, a ydeevnekrav might specify a maximum average response time of 200 milliseconds

Considerations: Setting ydeevnekrav involves balancing cost, development time, and risk. Targets should be realistic, testable, and
