标准范围

ISO/IEC 25023:2016根据ISO/IEC 25010中定义的特性和子特性，定义了定量评估系统和软件产品质量的质量度量，并打算与ISO/IEC 25010一起使用。它可以与ISO/IEC 2503n和ISO/IEC 2504n标准结合使用，或者更普遍地满足用户在软件产品或系统质量方面的需求。ISO/IEC 25023:2016包含以下内容:-每个特征和子特征的一组基本质量度量；-解释如何应用软件产品和系统质量度量。作为资料性附录，它包括质量措施使用注意事项（附录A）、用于定义产品或系统质量措施的质量管理体系（附录B）以及测量类型的详细说明（附录C）。ISO/IEC 25023:2016未将测量值的范围指定给额定水平或合规等级，因为这些值是根据系统、产品或产品的一部分的性质定义的，并取决于软件类别、完整性水平和用户等因素；需要。一些属性可能有一个理想的值范围，这不取决于特定的用户需求，而是取决于通用因素；例如，人类的认知因素。建议的质量措施主要用于在开发生命周期过程期间或之后对系统和软件产品进行质量保证和改进。ISO/IEC 25023:2016的主要用户是执行质量要求规范和评估活动的人员，这些活动是以下活动的一部分:-开发:包括需求分析、设计规范、编码和测试，直至生命周期过程中的验收；-质量管理:对软件产品或计算机系统进行系统检查，例如，在作为质量保证、质量控制和质量认证的一部分评估系统或软件产品质量时；-供应:与收单机构签订的根据合同条款供应系统、软件产品或软件服务的合同，例如，在资格测试中验证质量时；-采购:从供应商处采购系统、软件产品或软件服务时，包括产品选择和验收测试；-维护:基于质量度量的软件产品或系统的改进。

ISO/IEC 25023:2016 defines quality measures for quantitatively evaluating system and software product quality in terms of characteristics and subcharacteristics defined in ISO/IEC 25010 and is intended to be used together with ISO/IEC 25010. It can be used in conjunction with the ISO/IEC 2503n and the ISO/IEC 2504n standards or to more generally meet user needs with regard to software product or system quality.ISO/IEC 25023:2016 contains the following:- a basic set of quality measures for each characteristic and subcharacteristics;- an explanation of how to apply software product and system quality measures.It includes, as informative annexes, considerations for the use of quality measures (Annex A), QMEs used to define product or system quality measures (Annex B), and detailed explanation of measurement types (Annex C).ISO/IEC 25023:2016 does not assign ranges of values of the measures to rated levels or to grades of compliance because these values are defined based on the nature of the system, product or a part of the product, and depending on factors such as category of the software, integrity level, and users' needs. Some attributes could have a desirable range of values, which does not depend on specific user needs but depends on generic factors; for example, human cognitive factors.The proposed quality measures are primarily intended to be used for quality assurance and improvement of system and software products during or post the development life cycle process.The main users of ISO/IEC 25023:2016 are people carrying out quality requirement specification and evaluation activities as part of the following:- development: including requirements analysis, design specification, coding and testing through acceptance during the life cycle process;- quality management: systematic examination of the software product or computer system, for example, when evaluating system or software product quality as part of quality assurance, quality control and quality certification;- supply: a contract with the acquirer for the supply of a system, software product or software service under the terms of a contract, for example, when validating quality at qualification test;- acquisition: including product selection and acceptance testing, when acquiring or procuring a system, software product or software service from a supplier;- maintenance: improvement of the software product or system based on quality measurement.
