标准范围

ISO/IEC TR 9126-4:20 04提供了用于测量ISO/IEC 9126-1中定义的属性的使用质量指标。ISO/IEC TR 9126-2定义了外部度量，ISO/IEC TR 9126-3定义了用于测量ISO/IEC 9126-1中定义的子特性的内部度量。内部指标测量软件本身，外部指标测量包括软件的基于计算机的系统的行为，使用质量指标测量在特定使用环境中使用软件的效果。ISO/IEC TR 9126-4中列出的指标并非详尽无遗。开发人员、评估人员、质量经理和获取人员可以从ISO/IEC TR 9126-4中选择指标，用于定义需求、评估软件产品、测量质量方面和其他目的。2旨在与ISO/IEC 9126-1一起使用。ISO/IEC TR 9126-4包含:-如何应用软件质量度量的解释；——每个特征的一组基本度量；以及——如何在软件产品生命周期中应用度量的示例。它包括作为信息性附件的使用质量评估流程和报告格式。

ISO/IEC TR 9126-4:2004 provides quality in use metrics for measuring the attributes defined in ISO/IEC 9126-1. ISO/IEC TR 9126-2 defines external metrics and ISO/IEC TR 9126-3 defines internal metrics for measurement of the subcharacteristics defined in ISO/IEC 9126-1. Internal metrics measure the software itself, external metrics measure the behaviour of the computer-based system that includes the software, and quality in use metrics measure the effects of using the software in a specific context of use.

The metrics listed in ISO/IEC TR 9126-4 are not intended to be an exhaustive set. Developers, evaluators, quality managers and acquirers may select metrics from ISO/IEC TR 9126-4 for defining requirements, evaluating software products, measuring quality aspects and other purposes.

ISO/IEC TR 9126-2 is intended to be used together with ISO/IEC 9126-1.

ISO/IEC TR 9126-4 contains:

-- an explanation of how to apply software quality metrics;

-- a basic set of metrics for each characteristic; and

-- an example of how to apply metrics during the software product life cycle.

It includes as informative annexes a quality in use evaluation process and a reporting format.
