Full title and description

St ISO IEC 25030-2019 — Systems and software engineering — Software product Quality Requirements and Evaluation (SQuaRE) — Quality requirements. This standard provides guidance and requirements for specifying, negotiating and documenting quality requirements for software products within the SQuaRE framework, supporting the definition of measurable acceptance criteria and linking product quality needs to evaluation activities.

Abstract

ISO/IEC 25030:2019 is part of the SQuaRE family (ISO/IEC 25000 series) and focuses on quality requirements for software products. It defines concepts, processes and recommended practices to elicit, structure, quantify and manage quality requirements so they can be used for design, procurement, evaluation and acceptance. The standard helps translate stakeholder needs into verifiable quality characteristics and measures, and it describes how to prioritize, document and trace these requirements through the product lifecycle.

Scope

This standard specifies requirements and guidance for establishing quality requirements for software products. It describes the types of quality requirements (including functional and non-functional/non-behavioural requirements related to product quality attributes), how to express them in measurable terms, and how to link them to product quality models and evaluation activities. The scope covers definition, prioritization, documentation, negotiation and traceability of quality requirements across acquisition, development and maintenance contexts, and explains relationships with other SQuaRE standards used for quality measurement and evaluation.

Key topics and requirements

• Definitions and terminology for quality requirements within the SQuaRE framework.
• Classification of quality requirements aligned with product quality models (for example characteristics from ISO/IEC 25010).
• Guidance on expressing requirements in measurable, testable terms and establishing acceptance criteria.
• Processes for elicitation, prioritization and negotiation of quality requirements with stakeholders.
• Documentation templates and structure for quality requirements specifications.
• Traceability practices linking quality requirements to design, implementation and evaluation activities.
• Advice on tailoring requirements to different domains, acquisition types and lifecycle stages.
• Guidance on selecting metrics and measurement methods to support verification and validation of quality requirements.

Typical use and users

ISO/IEC 25030:2019 is used by requirements engineers, systems and software architects, QA and test managers, product owners, procurement officers, and contract managers. It supports organizations defining product quality needs for in-house development, supplier procurement and third-party evaluations. Typical activities include drafting quality requirements sections in specifications and contracts, preparing acceptance test plans, prioritizing non-functional needs, and establishing traceability from stakeholder needs to measurable product attributes.

Related standards

ISO/IEC 25030:2019 is part of the SQuaRE family and is commonly used alongside ISO/IEC 25010 (system and software product quality models), ISO/IEC 25000 (overview), ISO/IEC 25020 (measurement reference model), ISO/IEC 25040 (evaluation process), ISO/IEC 25051 (product quality requirements for off-the-shelf software), and lifecycle/process standards such as ISO/IEC 12207 and ISO/IEC 15288. It complements organizational quality standards like ISO 9001 when applied to software product quality concerns.
