功能点分析法的研究和改进

Improved Function Point Analysis

  • 摘要: 根据项目实践中的经验,将当前流行的软件规模度量方法——功能点分析法进行了改进。针对不同业务需求稳定性的差异,考虑到了需求在项目过程中的变化因素,在功能点分析法的每个功能点接口中分别加上一个需求稳定性的调整系数,将原有功能点逐个进行稳定性调节。本文通过一个实际的例子分析了改进前后的功能点数的变化情况,实验数据证明改进后的功能点数在项目推进过程中平稳的被完成,避免了传统的功能点数在项目后期出现较大的震荡。

     

    Abstract: An improved function point analysis (FPA) is proposed according to the project experience. According to difference of bussiness requierments and change factors in projects, a stability parameter is added into each function point of FPA to adjust original function point individually. A practical example is studied by the improved FPA. The experiment data proves that this method workes more exactly and more smoothly than traditional methods.
