面向非功能需求的软件规模度量方法研究

Research on Software Sizing Measurement Methods for Non-functional Requirement

针对非功能性需求如何选择软件规模度量方法的问题,介绍了IFPUG、NESMA等传统功能点分析方法,引入了软件非功能规模评估过程(SNAP)方法。该方法整合了功能性需求和非功能性需求的评估,并对其使用规则加以阐述,通过实际项目数据对其度量效果展开验证,为非功能性需求占比较高的项目如何评估工作量提供参考。

Regarding the issue of how to choose software sizing measurements standards for non-functional requirements,this paper introduces both traditional functional point analysis methods such as IFPUG and NESMA,as well as the Software Non-functional Assessment Process(SNAP)method.The method integrates the assessment of functional and non-functional requirements.This paper elaborates on its usage rules and verifies its measurement effectiveness through actual project data,providing a reference for evaluating the workload of projects with a high proportion of non-functional requirements.
