kvalitetskrav

Kvalitetskrav are explicit statements about the quality characteristics required for a product, service, process, or system. They define what is considered acceptable and verifiable by stakeholders, and are used to guide design, development, testing, and procurement. The term is common in Nordic contexts and is applied across industries.

Kvalitetskrav can be functional or non-functional. Functional requirements describe what the product should do, such as features and behavior. Non-functional requirements specify quality attributes like performance, reliability, safety, usability, maintainability, security, and compliance with standards or regulations.

Specification and verification are central to kvalitskrav. They are typically included in project briefs, procurement documents, or product specifications. To enable verification, each krav should be measurable and testable, with targets and acceptance criteria. Verification methods include inspections, testing, simulations, audits, and demonstrations.

Relation to standards and quality management is common. Kvalitetskrav align with quality management frameworks such as ISO 9001 and with product quality models like ISO/IEC 25010, which help define relevant quality characteristics and their metrics. They also support risk management by identifying critical quality attributes and their potential impacts.

Development and maintenance involve stakeholders, traceability, and life-cycle perspective. Kvalitetskrav should be created early, refined through design and testing, and maintained through changes to avoid misalignment. Clear prioritization helps balance feasibility with essential quality needs.

Examples include performance targets (response time under a given threshold), reliability metrics (mean time between failures), security requirements (encryption standards), and regulatory compliance (data protection rules) or service levels (availability and support response times).
