ISO/IEC TS 25025-2021 信息技术--系统和软件质量要求和评价--IT服务质量的测量 Information technology — Systems and software Quality Requirements and Evaluation (SQuaRE) — Measurement of IT service quality

This document defines quality measures useful for requirements and evaluation of IT service quality in terms of characteristics and sub-characteristics defined in ISO/IEC TS 25011.
This document contains a basic set of quality measures for each characteristic and sub-characteristic.
This document does not assign ranges of values of the quality measures to rated levels or to grades of compliance. Such values are defined based on the nature of the IT service, and so depends on factors such as category of the IT service or users' needs. Some attributes can have a desirable range of values which does not depend on specific user needs but generic factors, for example, service downtime. This document includes, in Annex A, considerations for the selection and application of quality measures.
The quality measures in this document are primarily intended to be used for quality evaluation and improvement of IT services during or after the development life cycle.st edition 2021-03 Information technology — Systems and software Quality Requirements and Evaluation (SQuaRE) — Measurement of IT service quality Technologies de l'information — Exigences de qualité et évaluation des systèmes et du logiciel (SQuaRE) — Mesure de la qualité du service informatique Reference number ISO/IEC TS 25025:2021(E) ？ ISO/IEC 2021 ISO/IEC TS 25025:2021(E) COPYRIGH
