    The purpose of the requirements definition phase is to produce a clear, complete, consistent, and testable(71 )of the technical requirements for the software product.During the requirements definition phase, the requirements definition team uses an iterative process to expand a broad statement of the system requirements into a complete and detailed specification of each function that the sofrware must perform. and each(72)that it must meet. The starting point is usually a set of high-level requirements from the(73)that describe the project or problem.In either case, the requirements definition team formulates an overall concept for the system and then defines(74)showing how the system will be operated, publishes the system and operations concept document, and conducts a system concept review(SCR).Following the SCR, the team derives(75)requirements for the system from the high level requirements and the system and operations concept. Using structured or object-oriented analysis, the team specifies the software functions and algorithms needed to satisfy each detailed requirement.

    解析：需求定义阶段的作用就是为软件产品产生一个清晰的、完整的、一致的、可测试的技术需求规格说明。在需求定义阶段，需求定义团队通过迭代过程把有关节系统需求的宽泛的陈述扩展成系列化统必须实现的各个功能的、完整而详细的规格说明，以及系列化统应该满足的各种准则。这个过程的起点通常是由用户提供的描述项目或问题的一组高级需求。在任何情况下，需求定义团队应该阐明与系统有关的整体概念，并且设定一种能够显示系统如何运作的情景，发布有关系统和运行的概念文档，并进行系统概念的评审(SCR)。在SCR之后，团队应该根据高级需求和系统运行概念导出详细的系统需求。通过结构化的或面向对象的分析技术，团队可以规范系统功能，说明满足每一细节需求的算法。
