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)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、detailed
B、outlined
C、total
D、complete

答案A

解析 在需求定义阶段,主要的目的是要提山一份清晰的、全面的、一致的和可测试性的规格说明书,为软件的开发作为技术规定。在需求定义期间,需求定义组使用迭代的过程形成一个完整的、详细的规格说明书,在该说明书中,包括软件必须执行的每个功能和必须满足的标准。在此阶段的开始,一般是一系列来自客户的对有关问题或项目的较高层次描述的需求。另一方面,需求定义组必须对系统有总的把握和理解,接着定义场景来说明系统将如何运行,发布系统和使用说明文档,以及指导系统概念评审(SCR)。根据SCR,需求分析组可以从高层的需求,系统和操作概貌来导出整个系统详细需求。通过使用结构化或面向对象分析方法,需求分析组定义软件功能和算法,以满足每个详细需求。
