ISO/IEC 25063:2014描述了使用环境描述的通用行业格式（CIF），并规定了现有、预期、实施或部署系统使用环境的高级和详细描述的内容。使用上下文描述包括有关用户和其他利益相关者群体、每个用户群体的特征、用户目标、用户任务以及系统使用环境的信息。 使用说明的上下文适用于软件和硬件系统、产品或服务（不包括通用产品，如显示屏或键盘）。重要的是收集和分析当前环境的信息，以便理解并描述将应用于未来系统的环境。 使用环境描述从不同用户群体和其他利益相关者的角度提供了一系列与交互式系统的分析、规范、设计和评估相关的数据。

ISO/IEC 25063:2014 describes the Common Industry Format (CIF) for context of use descriptions and specifies the contents of both high-level and detailed descriptions of the context of use for an existing, intended, implemented or deployed system. A context-of-use description includes information about the users and other stakeholder groups, the characteristics of each user group, the goals of the users, the tasks of the users, and the environment(s) in which the system is used. The context of use description is applicable to software and hardware systems, products or services (excluding generic products, such as a display screen or keyboard). It is important to gather and analyse information on the current context in order to understand and then describe the context that will apply in the future system. The context of use description provides a collection of data relevant for analysis, specification, design and evaluation of an interactive system from the perspective of the various user groups and other stakeholders.
