本文档支持系统用户对一致、完整、准确和可用信息的兴趣。它涉及两种可用的标准化方法:a）过程标准，其中规定了获取和提供信息产品的方式；b）信息产品标准，其中规定了信息的特性和功能要求。 根据ISO/IEC/IEEE 12207和ISO/IEC/IEEE 15288:2015的定义，采购和供应活动构成软件或系统生命周期的协议过程。为用户获取和提供信息及相关服务是这些过程的专业化。这些服务可以在信息管理过程的任何部分获得和提供，例如: 信息管理； ？信息设计与开发； ？信息编辑和审查协调； 信息测试，尤其是可用性测试； ？信息生产和包装； ？信息分发和交付； ？就信息开发工具和支持系统的选择和实施提供建议；和 信息开发流程改进。 本文档概述了与用户获取和提供信息相关的信息管理流程。它将协议流程（采购和供应）应用于用户信息，并解决了该信息要求的准备工作。 这些要求是本文件中讨论的用户信息规范和工作说明书的核心。本文件还阐述了采购和供应过程中主要文件输出的要求: 招标书和文件产品和服务的建议书。

This document supports the interest of system users in having consistent, complete, accurate, and usable information. It addresses both available approaches to standardization: a) process standards, which specify the way that information products are to be acquired and supplied; and b) information product standards, which specify the characteristics and functional requirements of the information. As defined in ISO/IEC/IEEE 12207 and ISO/IEC/IEEE 15288:2015, the acquisition and supply activities make up the agreement processes of the software or system life cycle. Acquisition and supply of information for users and related services are specializations of those processes. Such services can be acquired and supplied for any part of the information management process, such as the following: — information management; — information design and development; — information editing and review coordination; — information testing, particularly usability testing; — information production and packaging; — information distribution and delivery; — advice on the selection and implementation of information development tools and supporting systems; and — information development process improvement. This document provides an overview of the information management processes that are relevant to the acquisition and supply of information for users. It applies the Agreement processes (acquisition and supply) to information for users, and addresses the preparation of requirements for this information. These requirements are central to the information for users specification and statement of work discussed in this document. This document also addresses requirements for primary document outputs of the acquisition and supply process: the request for proposal and the proposal for documentation products and services.
