基于CMMI的信息系统需求变更度量问题及其改进方法

Research on the problems of information system requirement changes based on CMMI and countermeasures

度量是管理的基础,将度量引入需求变更管理是提高系统开发质量的有效途径。CMMI作为需求变更度量指导方法,具有一定的可行性,但也存在着问题。针对基于CMMI的信息系统需求变更度量存在的问题,先对它们进行分析评述,然后提出了相应的改进方法及方案。

As measurement is the foundation of management,the measurement can be introduced into requirement change management which helps to improve the project.It is reasonable to use CMMI to guide requirement changes measurement,but there are still some problems.This paper discusses the measurement problems of information system requirement changes based on CMMI,analyzes their comments,and then proposes corresponding improved methods and programs.
