中文名称：系统和软件工程 系统和软件质量要求和评估（SQuaRE） 使用中的质量模型

英文名称：Systems and software engineering — Systems and software Quality Requirements and Evaluation (SQuaRE) — Quality-in-use model

发布日期：2023-11

标准范围

本文件定义了一个由三个特征（进一步细分为子特征）组成的使用中质量模型，当产品或系统在指定的使用环境中使用时，这些特征可以影响利益相关者。该模型适用于整个信息系统和IT服务系统，包括在用的计算机系统和在用的软件产品。本文件提供了一组质量特征，用于指定、测量、评估和改进使用中的质量。在本文件中，由于使用环境被指定为使用中质量的先决条件，因此当产品或服务打算满足使用环境的变化时，需要重新指定使用环境以改变先决条件。该模型尤其可以由负责指定和评估软件产品质量的人员应用，例如开发人员、获取者、质量保证和控制人员以及独立评估人员。产品开发期间可受益于质量模型使用的活动可包括但不限于:-确定正在使用的信息系统和IT服务系统的需求；-验证使用中质量要求规范的全面性；-确定信息系统和IT服务系统设计目标，以确保使用中的质量；-确定使用中的质量控制标准，作为整体质量保证的一部分；-确定资讯系统及资讯科技服务系统或多个资讯系统的验收准则；-制定措施，解决在特定使用环境中使用产品的后果；-在使用资讯系统及资讯科技服务系统时，提出道德考量的评估项目；-支持数字化活动的治理。

This document defines a quality-in-use model composed of three characteristics (which are further subdivided into sub-characteristics) that can influence stakeholders when products or systems are used in a specified context of use. This model is applicable to the entire spectrum of information system and IT service system, including both computer systems in use and software products in use.
This document provides a set of quality characteristics for specifying, measuring, evaluating and improving quality-in-use.
In this document, because context of use is specified as prerequisite of quality-in-use, context of use is necessary to be re-specified to change prerequisite when a product or service intend to fulfil to context of use changes.
The model can be applied, in particular, by those responsible for specifying and evaluating software product quality, such as developers, acquirers, quality assurance and control staff, and independent evaluators. Activities during product development that can benefit from the use of the quality model can include, but are not limited to:
- identifying requirements for information system and IT service system in use;
- validating the comprehensiveness of a quality-in-use requirements specification;
- identifying information system and IT service system design objectives for quality-in-use;
- identifying quality-in-use control criteria as part of overall quality assurance;
- identifying acceptance criteria for information system and IT service system or information systems;
- establishing measures to address the consequences of using products in specified context-of -use;
- presenting evaluation items for ethics considerations when using information system and IT service system;
- supporting governance of digitalization activities.
