一种基于数据挖掘的量化新增需求代码量的分析方法

摘要

The requirements evolve frequently during software development. And,it is an important factor leading to the failure of software projects. Accurate analysis of the impact of requirements evolution will effectively help decision makers to reduce the risks of software project failure. Among all the risks,how to quantify the effect of newly added requirements on software project is particularly a problem hard to be dealt with. This paper proposes a quantified analysis method for requirement evolution impact using data mining. It clusters the newly added requirements with existing requirements of the software project first, and then analyses the clustering results. This method can comparatively quantify the lines of code to be created by the new requirements.%需求演化频繁发生于软件项目中,并且在很大程度上影响着软件项目的成败.对需求演化的影响进行准确的估算,将有效地帮助项目管理者降低软件项目失败的风险.其中,如何量化新增需求对软件项目的影响,是一个尤其难以解决的问题.提出一种基于数据挖掘的需求演化影响的量化分析方法,将新增需求与软件项目已有需求进行聚类,对于聚类结果进行分析,能够相对准确地量化新增需求将要产生的代码量.
