本文件为指定用户需求提供了一个框架和一致的术语。它规定了用户需求规范的通用行业格式（CIF），包括内容元素和说明这些需求的格式。 注1:用户需求规范是一组用户需求的正式文档，有助于开发和评估可用的交互系统。 在本文件中，用户需求是指: a） 实现预期结果的用户-系统交互要求（包括系统输出及其属性的要求）； b） 使用相关的质量要求，这些要求规定了与用户与交互系统交互的结果相关的质量标准，并可用作系统验收的标准。 注2 ISO/IEC 25030引入了质量要求的概念。本文件中与使用相关的质量要求是一种特殊类型的质量要求。 用户需求规范的内容元素旨在用作ISO 9241-210中规定的活动以及以人为中心的设计过程（如ISO 9241-220中的设计过程）产生的文件的一部分。 本文档旨在供需求工程师、业务分析师、产品经理、产品所有者和从第三方获取系统的人员使用。 CIF系列标准涉及可用性相关信息（如ISO 9241所述）- 11和ISO/IEC TR 25060）。 注3除了可用性，用户需求还可以包括其他方面，如ISO 9241-220中引入的以人为中心的质量，以及ISO/IEC 25010、ISO/IEC TS 25011和ISO/IEC 25030中提出的其他质量方面。 注4:虽然本文件是为交互式系统开发的，但本指南也可应用于其他领域。 本文件未规定任何类型的方法、生命周期或过程。用户需求规范的内容元素可用于迭代开发，其中包括需求的细化和演化（例如，在敏捷开发中）。

This document provides a framework and consistent terminology for specifying user requirements. It specifies the common industry format (CIF) for a user requirement specification including the content elements and the format for stating those requirements. NOTE 1 A user requirements specification is the formal documentation of a set of user requirements, which aids in the development and evaluation of usable interactive systems. In this document, user requirements refers to: a) user-system interaction requirements for achieving intended outcomes (including requirements for system outputs and their attributes); b) use-related quality requirements that specify the quality criteria associated with the outcomes of users interacting with the interactive system and can be used as criteria for system acceptance. NOTE 2 ISO/IEC 25030 introduces the concept of quality requirements. The use-related quality requirements in this document are a particular type of quality requirement. The content elements of a user requirements specification are intended to be used as part of documentation resulting from the activities specified in ISO 9241-210, and from human centred design processes, such as those in ISO 9241-220. This document is intended to be used by requirements engineers, business analysts, product managers, product owners, and people acquiring systems from third parties. The CIF series of standards addresses usability-related information (as described in ISO 9241-11 and ISO/IEC TR 25060). NOTE 3 In addition to usability, user requirements can include other perspectives, such as human-centred quality introduced in ISO 9241-220, and other quality perspectives presented in ISO/IEC 25010, ISO/IEC TS 25011, and ISO/IEC 25030. NOTE 4 While this document was developed for interactive systems, the guidance can also be applied in other domains. This document does not prescribe any kind of method, lifecycle or process. The content elements of a user requirements specification can be used in iterative development which includes the elaboration and evolution of requirements (e.g. as in agile development).
