标准范围

ISO/IEC TR 25021:2007定义了在整个软件产品生命周期中用于软件产品质量要求和评估（SQuaRE）的一组质量度量元素。虽然一些质量测量元件可以用作独立的质量测量，但它们的主要用途是作为ISO/IEC TR 9126-2、ISO/IEC TR 9126-3和ISO/IEC TR 9126-4中所述的其他方形测量的构件。ISO/IEC TR 25021:2007构成了ISO/IEC 9126与后续方形系列标准之间的联系。ISO/IEC TR 25021:2007包含资料性附录，记录了ISO/IEC 9126中定义的质量度量元素和质量度量、特性和子特性之间的交叉引用关系。ISO/IEC TR 25021:2007所属的质量测量部门也提供了可在整个产品开发周期内使用的质量测量示例-周期这些措施在该部门的其他文件中定义，并与软件产品质量模型中的质量特征相对应，如未来国际标准ISO/IEC 25010（代替ISO/IEC 9126-1）中所述的质量特征。ISO/IEC TR 25021:2007旨在与方形系列中的其他标准（ISO/IEC 25030）和产品质量评估（未来的国际标准ISO/IEC 25040）一起使用。

ISO/IEC TR 25021:2007 defines the set of quality measure elements to be used throughout the software product life cycle for the purpose of Software Product Quality Requirement and Evaluation (SQuaRE). While some quality measure elements can be used as standalone quality measures, their main purpose is to be the building blocks for other SQuaRE measurements as described in ISO/IEC TR 9126-2, ISO/IEC TR 9126-3 and ISO/IEC TR 9126-4. ISO/IEC TR 25021:2007 constitutes the link between ISO/IEC 9126 and the subsequent SQuaRE series of standards.ISO/IEC TR 25021:2007 contains informative annexes documenting the cross-reference relationship between the quality measure elements and quality measures, characteristics and subcharacteristics defined in ISO/IEC 9126.The Quality Measurement Division, of which ISO/IEC TR 25021:2007 is a member, also offers examples of quality measures that can be used across the product development life-cycle. These measures are defined in the other documents in the division and correspond to the quality characteristics in a software product quality model such as that described in the future International Standard ISO/IEC 25010 (replacing ISO/IEC 9126-1). ISO/IEC TR 25021:2007 is designed to be used, in particular, with other standards in the SQuaRE series that address quality requirements (ISO/IEC 25030) and product quality evaluation (the future International Standard ISO/IEC 25040).
