本文件提供了开发质量度量的框架。本文件内容如下:-质量测量参考模型；-不同类型的质量度量之间的关系；-选择质量标准的指南；-施工质量措施指南；-规划和实施测量的指南；-测量结果应用指南。它包括选择质量度量和质量度量元素（附录A）、评估测量的可靠性和质量度量的有效性（附录B）、记录质量度量的元素（附录C）、质量度量的标准化测量功能（附录D）以及ISO/IEC/IEEE 15939中的测量信息模型（附录E）。本文件可用于设计、识别、评估和执行系统和软件产品质量、使用质量、数据质量和IT服务质量的测量模型。该参考模型可供开发商、收购方、质量保证人员和独立评估人员使用，主要由负责指定和评估信息和通信技术（ICT）系统和服务质量的人员使用。

This document provides a framework for developing quality measurement.The contents of this document are as follows:— quality measurement reference model;— relationships among different types of quality measures;— guidelines for selecting quality measures;— guidelines for constructing quality measures;— guidelines for planning and performing measurements;— guidelines for the application of measurement results.It includes considerations for selecting quality measures and quality measure elements (Annex A), assessing the reliability of measurement and the validity of quality measures (Annex B), elements for documenting quality measures (Annex C), normalized measurement function for quality measures (Annex D) and the measurement information model in ISO/IEC/IEEE 15939 (Annex E).This document can be applied for designing, identifying, evaluating and executing the measurement model of system and software product quality, quality in use, data quality and IT service quality. This reference model can be used by developers, acquirers, quality assurance staff and independent evaluators—essentially by people responsible for specifying and evaluating the quality of information and communication technology (ICT) systems and services.
