问题 The purpose of the requirements definition phase is to produce a clear, complete, consistent, and testable(36)of the technical requirements for the software product.During the requirements definition phase, the requirements definition team uses an interative process to expand a broad statement of the system requirements into a complete and detailed specification of each function that the software must perform and each(37)that it must meet. The starting point is usually a set of high level requirements from the(38)that describe the project or problem.In either case, the requirements definition team formulates an overall concept for ’the system and then defines(39)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(40)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.

选项 A、cotailed
B、outlined
C、total
D、complete

答案B

解析 需求分析阶段的主要目的是为软件产品提出一个清晰的、完整的、一致的、可测试的需求规格说明书(specification)。在需求分析阶段,需求定义团队使用迭代过程把有关系统需求的宽泛的陈述扩展成有关系统必须执行的各个功能的完整而详细的规格说明,以及系统应该满足的各种标准(criterion)。这个过程的起点通常是由用户(customer)提供的描述项目或问题的一组高级需求。在任一种情况下,需求定义团队都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场景(scenarios),发布有关系统和运行的概念文档,以及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与运行概念导出详细的(outlined)系统需求。通过使用结构化的或面向对象的分析技术,团队可以规范系统功能,说明满足每一个细节需求的算法。
