A Study of SOFTWARE Quality Evaluation by the Use of Statistical Methods

통계적방법(統計的方法)을 이용(利用)한 SOFTWARE 품질평가(品質評價)에 관한 연구(硏究)

The quality of a final SOFTWARE PACKAGE depends on many complicated factors in the software development process. This paper describes ststistical methods for establishing relationships between final quality and development process factors. The final software quality is represented by the number of errors through the system test phase. The data presented here were gathered during the course of a real IS-month development project. Regression theory is used for data analysis. Some of the interesting results include the observation that specification changes during the development process have an adverse effect on final software quality.
