问题 The purpose of the requirements definition phase is to produce a clear, complete, consistent, and testable(6)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 software must perform and each(7)that it must meet. The starting point is usually a set of high level requirements from the(8) that describe the project or problem.In either case, the requirements definition team formulates an overall concept for the system and then defines(9)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(10)require merits for the system from the high level requirements and the system and operations conceptusing 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 需求定义阶段的目的就是,需求定义团队使用迭代过程来将系统需求陈述扩展成完整的详细的对软件必须实现的每个功能的规格说明和必须遵守的标准准则。开始点就是一系列高级的从用户对问题和工程的描述中获得的需求说明。在另外一种情况下,需求定义团队必须为系统定义完整的概念,并且定义一种能够展示系统如何工作的情景,发布系统和操作概念文档,并进行系统概念的评审。紧随着SCR,团队从高级文档以及系统和操作概念中得出详细需求说明。使用结构化或者面向对象的分析,对软件功能和算法进行细化,这些功能和算法需要满足每一个细节要求。
