摘要

需求分析被认为是开发高质量软件的最重要的阶段,因为由糟糕和不充分的需求分析引起的错误很可能在设计和实现阶段蔓延。这些错误被认为是耗时且修复成本最高的。因此,需求分析是决定软件项目成功或失败的阶段。糟糕的需求分析增加了70-85%的开发成本,这需要在软件项目的所有阶段进行返工。可以观察到,当关注软件的功能时,非功能属性经常被忽略。许多软件系统的失败是因为忽视了非功能性需求。因此,在软件开发过程中对非功能需求的满足程度进行测量是十分必要的。

Quantification of non-functional requirements
Requirements Analysis is considered as the most important phase for the development of quality software because errors caused by poor and inadequate requirement analysis are likely to creep in design and implementation phase. These errors are observed as time-consuming and most expensive to repair. Thus, Requirement Analysis is the phase, which determines the success or failure of a software project. Poor requirement analysis increases the cost of development by 70-85%, which requires reworking on all phases of software project. It is observed that non-functional properties are often ignored while focusing on the functionality of the software. Many software systems have failed because of negligence of non-functional requirements. Therefore, it is necessary to measure the satisfaction level of non-functional requirement during software development process.
