Full title and description

Systems and software engineering — Systems and software quality requirements and evaluation (SQuaRE) — Measurement of quality in use (ISO/IEC 25022:2016). This international standard defines a suggested set of quality-in-use measures that correspond to the quality-in-use characteristics of ISO/IEC 25010 and explains how those measures can be applied to evaluate the effects of a system or software product when actually used by real users in a specified context of use.

Abstract

ISO/IEC 25022:2016 provides a basic set of measures for each quality-in-use characteristic (effectiveness, efficiency, satisfaction, freedom from risk and context coverage), guidance on measurement methods and normalisation options, and informative annexes with examples and evaluation-process guidance. The measures are intended for quality assurance and management and are to be used together with the ISO/IEC 25010 quality model.

Scope

ISO/IEC 25022:2016 specifies measures and measurement guidance for the quality-in-use characteristics defined in ISO/IEC 25010. It is applicable to the use of any human–computer system, including software products that form part of a system, and is intended to support development, acquisition, evaluation, maintenance and quality management activities by quantifying how well users can achieve goals in specified contexts of use. The standard does not impose fixed numeric thresholds; values are defined according to the context and users' needs.

Key topics and requirements

• Defines quality-in-use measures for the characteristics in ISO/IEC 25010: effectiveness, efficiency, satisfaction, freedom from risk, and context coverage.
• Provides a basic (non-exhaustive) set of measures and options for normalisation and aggregation.
• Includes informative annexes with examples (context coverage), normalisation options, mapping to ISO 9241‑11 usability concepts, an evaluation process, relationships between quality models, and measurement concepts.
• Intended uses: quality assurance, product selection/acceptance, acquisition, evaluation and maintenance activities; primarily for managers and practitioners responsible for specifying and evaluating quality-in-use.
• Does not set graded compliance levels; measurement interpretation is context-dependent and intended to be adapted to the user population and use scenarios.

Typical use and users

Typical users include software and systems developers, quality managers, evaluators, acquirers/procurement teams, and maintainers who need objective measures of how a product performs for end users in real-use contexts. The standard is used to design measurement plans, select or adapt measures for usability and quality-in-use evaluation, and to support acceptance testing and continuous improvement.

Related standards

Part of the ISO/IEC 25000 SQuaRE family. Key related standards include ISO/IEC 25010 (quality model and quality-in-use characteristics), ISO/IEC 25020/25021 (measurement framework and measure elements), ISO/IEC 25023 (product and system quality measurement), ISO/IEC 25024 (data quality measurement) and other SQuaRE parts that cover planning, requirements and evaluation processes. The original ISO/IEC 25022 superseded earlier ISO/IEC 9126-4 content and remains aligned with the SQuaRE measurement division.

FAQ

Q: What is this standard?

A: ISO/IEC 25022:2016 is an international standard that specifies measures and guidance for assessing quality in use of systems and software (the user-centred outcomes defined in ISO/IEC 25010).

Q: What does it cover?

A: It covers a suggested set of measures for the quality-in-use characteristics (effectiveness, efficiency, satisfaction, freedom from risk and context coverage), measurement methods, normalisation options and informative examples/annexes to help implement evaluations that reflect real user contexts.

Q: Who typically uses it?

A: Developers, evaluators, quality managers, acquirers and maintainers who need objective, repeatable measures of how well users can achieve goals with a product or system in specific contexts of use.

Q: Is it current or superseded?

A: ISO/IEC 25022:2016 is the published edition (2016) and remains the current base publication; however, the SQuaRE programme has active work to revise and consolidate parts of the measurement series and a committee draft (ISO/IEC CD 25000-22) has been registered to replace or update the part — users should check the ISO catalogue or national body notices for the latest status before purchase or formal adoption.

Q: Is it part of a series?

A: Yes — it is part of the ISO/IEC 25000 SQuaRE series (Systems and software quality requirements and evaluation), specifically the Quality Measurement division (the 2502n set of parts). It is intended to be used in conjunction with companion SQuaRE parts such as ISO/IEC 25010 and ISO/IEC 25023.

Q: What are the key keywords?

A: Quality in use, usability measurement, effectiveness, efficiency, satisfaction, freedom from risk, context coverage, SQuaRE, ISO/IEC 25022.
