由于开发是个迭代的过程，所以需求定义并没有终止在初始的项目定义阶段。
Since development is an iterative process, requirements definition does not end in the initial project-definition phase.
因此可以节约一定时间，特别在构建需求更频繁的项目初始阶段更是如此。
So you can save some time especially during in the initial phase of a project where the builds are needed more often.
您需要在RUP的初始阶段做一些初始的需求建模，但不需要像传统主义者想得那样全面。
You need to do some initial requirements modeling during RUP's Inception phase, but it doesn't need to be as comprehensive as traditionalists think.
初始阶段：通过获得对所有需求的高层次的理解和确立系统的范围来建立对系统将要构建什么的良好理解。
Inception: establish a good understanding of what system to build by getting a high-level understanding of all the requirements and establishing the scope of the system.
本书也提供了每个项目阶段非常详细的突破，从先启阶段开始，其中包括了建立项目愿景和初始需求。
The book also provides a highly detailed breakdown of each project phase, starting with Inception, which includes establishing the project vision and initial requirements gathering.
例如，可以在初始阶段进行所有的需求收集工作，而在精化阶段进行设计工作。
For example, you could do all requirement-gathering in the Inception phase and make the Elaboration phase the phase in which you do your design work.
需求工程是软件系统开发生命周期的初始阶段，其最终结果是得到关于用户需求的准确、全面、形式化的需求描述。
Requirements Engineering is the initial stage in the software development life cycle, whose final product is the precise, complete, formal document about the users 'needs.
