问题 Ravi, like many project(71), had studied the waterfall model of software development as the primary software life-cycle(72). He was all set to use it for an upcoming project, his first assignment. However, Ravi found that the waterfall model could not be used because the customer wanted the software delivered in stages, something that implied that the system had to be delivered and built in(73) and not as(74).
   The situation in many other projects is not very different. The real world rarely presents a problem in which a standard process, or the process used in a previous project, is the best choice. To be the most suitable, an existing process must be(75)to the new problem.
   A development process, even after tailoring, generally cannot handle change requests. To accommodate change requests without losing control of the project, you must supplement the development process with a requirement change management process.
(75)
选项 A、 modified
B、 used
C、 suited
D、 tailored
答案D
解析 本题考查英语的基本知识。和许多项目经理一样，Ravi研究了作为主要软件开发生命周期过程的瀑布模型，但是，他发现瀑布模型不能满足要求，原因是客户希望软件分阶段提交。也就说明系统必须按照部分构建和交付系统，而不是作为一个整体进行。这种情况在很多其他项目中也类似。现实世界中，很难有一种标准的过程或在前期的项目中使用的过程作为目前项目的最佳选择。因此，为了达到最佳的适应性，需要针对新的问题，对已有开发过程进行裁剪(针对新的问题，做适应性修改)。但是，即使经过裁剪，一个开发过程也很难应对变更的需求。因此，为了适应变化的需求而不失去对项目的控制，必须用需求变更管理过程对开发过程进行补充。
