소프트웨어공학수준이 결함제거효율성에 미치는 영향 = The Influence of Software Engineering Levels on Defect Removal Efficiency

다국어 초록 (Multilingual Abstract)

The role of software process is getting more important to make good quality softwares.
One of the measures to improve the software process is Defect Removal Efficiency(DRE).
DRE gives a measure of the development team ability to remove defects prior to release. It is calculated as a ratio of defects resolved to total number of defects found. Software Engineering Levels are usually decided by CMMI Model. The model is designed to help organizations improve their software product and service development, acquisition, and maintenance processes. The score of software engineering levels can be calculated by CMMI model. The levels are composed of the three groups(absent, average, and advanced).
This study is to find if there is any difference among the three categories in term of the result of software engineering levels on DRE. We propose One way ANOVA to analyze influence of software engineering levels on DRE. Bootstrap method is also used to estimate the sampling distribution of the original sample because the data are not sampled randomly.
The method is a statistical method for estimating the sampling distribution of an estimator by sampling with replacement from the original sample. The data were collected in 106software development projects by the survey.
The result of this study tells that there is some difference of DRE among the groups. The higher the software engineering level of a specific company becomes, the better its DRE gets,which means that the companies trying to improve software process can increase their good management performance.
