Full title and description

ISO/IEC 25023-2016 — Systems and software engineering — Systems and software Quality Requirements and Evaluation (SQuaRE) — Measurement of system and software product quality. This international standard specifies a set of product-quality measures derived from the ISO/IEC 25010 product quality model, together with definitions, measurement methods and guidance for applying the measures to assess the quality of software and system products.

Abstract

ISO/IEC 25023:2016 defines standardized measures for evaluating system and software product quality. It maps measures to the ISO/IEC 25010 product quality characteristics (such as functional suitability, performance efficiency, compatibility, usability, reliability, security, maintainability and portability), describes base and derived measures, and provides guidance on measurement units, data collection, and interpretation. The standard is intended to support objective, repeatable assessment and comparison of product quality across projects and tools.

Scope

This standard specifies product quality measures for system and software products and provides definitions, measurement constructs (base measures, derived measures), measurement units and recommended collection methods. It is intended to be used with the broader SQuaRE suite (ISO/IEC 25000-series) and applies to internal and external product quality evaluation activities, supporting quality requirements, testing, benchmarking and process improvement.

Key topics and requirements

• Definitions of product-quality measures aligned to the ISO/IEC 25010 quality model.
• Specification of base measures (direct observations) and derived measures (combinations/ratios of base measures).
• Measurement units, scales and definitions for consistent data collection and reporting.
• Guidance on measurement methods, sampling, instrumentation and automation where applicable.
• Mapping of measures to quality characteristics and subcharacteristics (functional suitability, performance efficiency, reliability, security, usability, maintainability, portability, etc.).
• Recommendations for interpreting results, establishing thresholds and using measures for decision making.
• Examples and templates for common product-quality measures to aid practical adoption.

Typical use and users

ISO/IEC 25023 is used by quality assurance teams, test engineers, product managers, software architects, measurement specialists, procurement and compliance officers, and tool vendors. Typical uses include defining measurable quality requirements, designing test and measurement plans, benchmarking products, monitoring product quality over time, and supporting contractual quality criteria in procurement or supplier evaluation.
