Risk management or risk-based approach of software project management was developed to explain the effects of requirement uncertainty, control standardization, interactions on software quality. Based on a prior theory, five hypotheses were derived and empirically tested using a survey design. Data from 117 members in 3 SI companies support for the path model, and three of five hypotheses. The results showed that decreases in requirement uncertainty and increases in control standardization were directly associated with increases in the interactions between user and project teams, which, in turn, led to increases software quality. The findings suggested that the direct effect on software quality is primarily due to the interactions between user and project teams, rather than requirement uncertainty and control standardization.

With rapid development of information and communication technologies, open collaboration can be eased through the Internet. Open source software, as a representative area of open collaboration, is developed and adopted to various fields. In this research, based on organizational learning theory, we examine the impacts of exploration and exploitation on innovation performance in open source software development projects. We define knowledge exploration as a number of developers from outside organization and knowledge exploitation as the ratio of member of an organization who participated in an open source software project managed by the organization. For analysis, we collect data of 4794 projects from github which is a representative open source software development platform using Web crawler developed by Python. As a result, we find that excessive exploration has curvilinear (invers U-shape) relationship on project performance. On the other hand, exploitation with enough external developers will positively impact on project performance.

소프트웨어 측정분야는 30년 이상 수많은 연구가 있어 왔으나 아직까지 구체적인 소프트웨어 개발노력, 개발기간과 비용 추정 모델이 없는 실정이다. 소프트웨어 개발기간을 추정하기 위한 기존의 모델들은 사용된 데이터 크기가 적고 과거 프로젝트들을 대상으로 하고 있어 현재의 복잡하고 다양한 개발환경에 적용하는데 제약이 따른다. 따라서, Oligny et al.은 ISBSG Benchmark Release 4의 396개 프로젝트에 대해 개발기간이 개발플랫폼에 영향을 받음을 제기하여 각 개발플랫폼에 따른 개발기간 추정 모델을 제시하였다. 본 논문은 Oligny et al. 모델들을 ISBSG Benchmark Release 6의 534개 프로젝트에 대해 적용한 결과 개발기간이 개발플랫폼에 영향을 적게 받음을 밝혔다. 따라서, 개발기간에 보다 영향을 미치는 개발형태를 채택해, 개발형태에 따른 개발기간 추정 모델을 제시하였다. 제안된 모델들은 개발 플랫폼의 영향보다 개발기간 추정에 보다 많은 영향을 미침을 밝혔으며, 개발기간 추정시 개발형태별로 추정하는 모델 적용이 보다 타당함을 알 수 있다.

본 연구에서는 소프트웨어 유지보수에 영향을 주는 생산성 요소들을 투입인력 특성, 소프트웨어의 기술적 특성 및 유지보수 환경특성 등 3개의 영역으로 구분하였다. 또한 실제 유지보수 프로젝트의 데이터를 수집하여 소프트웨어 유지보수 규모와 생산성 요소를 결합한 투입인력 규모예측을 위한 다양한 회귀모형을 통계적 분석에 의해 검증하였다. 결론적으로 소프트웨어유지보수 프로젝트의 투입인력 규모예측을 위해 가장 유의한 모형으로 요인점수에 의한 선형모형이 최종 모형으로 제시되었다.

소프트웨어 결함에 대한 관심이 높아지고 있다. 기업은 소프트웨어를 개발하는 조직, 고객대응 조직, 품질관리 조직 등 다양한 방법과 채널을 이용하여 개선을 위한 노력을 하고 있다. 이렇게 수집된 결함 데이터 들을 그 조건과 용도에 맞게 분석하여 소프트웨어 결함을 최소화하고 나아가 제품품질 향상에 기여할 수 있다. 본 연구에서 기업용 소프트웨어의 결함 추이를 테스트 성숙도 모델을 기반으로 분석하여 결함 예방 프로세스를 수립하고 프로젝트에 적용하여 106개의 결함이 16개로 감소하였다. 본 연구는 소프트웨어 품질활동 중 기본이 되는 기존결함에 관심을 가짐으로서 최소한의 자원을 활용하여 소프트웨어 제품 품질을 개선할 수 있는 방안을 제시하는데 의의를 가진다.

Software Estimations provide an inclusive set of directives for software project developers, project managers, and the management in order to produce more realistic estimates based on deficient, uncertain, and noisy data. A range of estimation models are being explored in the industry, as well as in academia, for research purposes but choosing the best model is quite intricate. Estimation by Analogy (EbA) is a form of case based reasoning, which uses fuzzy logic, grey system theory or machine-learning techniques, etc. for optimization. This research compares the estimation accuracy of some conventional data mining models with a hybrid model. Different data mining models are under consideration, including linear regression models like the ordinary least square and ridge regression, and nonlinear models like neural networks, support vector machines, and multivariate adaptive regression splines, etc. A precise and comprehensible predictive model based on the integration of GRA and regression has been introduced and compared. Empirical results have shown that regression when used with GRA gives outstanding results; indicating that the methodology has great potential and can be used as a candidate approach for software effort estimation.

The use of Project Management Information System (PMIS) is increasing in project management industries such as construction, defense, manufacturing, software development, telecommunication, etc. It is generally known that PMIS helps to improve the quality of decision making in project management, and consequently improves the project performance. However, how much and which parts of project management performance are affected by PMIS still need to be studied further. The purpose of this study is to investigate the impact of PMIS quality on project management performance. We collected data from various project based industries such as construction, defense, manufacturing, software development and telecommunication by using survey questionnaire. PMIS quality was measured in three dimensions. They are system quality, information quality and service quality. Project management performance was measured in nine variables such as time reduction, work accuracy, cost management, etc. Statistical analyses such as multiple regression were used to analyze the data. The results showed that PMIS quality had significant impacts on the project management performance and user satisfaction. It was notable that only two dimensions out of the three PMIS quality dimensions, system quality and information quality, affected the project management performance. Also, it was found that PM performance played a mediating role between PMIS and user satisfaction, and between PMIS and reuse intention. The contribution of this research is that it helps to clarify what aspects of PMIS affect the project management performance and user satisfaction.

The purpose of this study is to investigate on tideland recalamation project as a part of situation on farm land improvement measures in North Korea. By using satelite image data beyond the national boundaries, it makes possbile to analyze tideland reclamation projects, and owing to the developed software and procedure we can analyze data regardless of difference in data acquistion date. Satellite image data LANDSAT JEARS-1 data are mainly used, and analyzing software ER Mapper, ERDAS , IDRISI are used . Reclamation survey result made by the ministry of unification in 1994 were examined by means of remote sensing using satellite image data. The results are ; Completed and/or partly completed project are 24, 596ha and planned are about 142, 223 ha, 166, 819 ha in total. However, they already reported about 300 thousand ha would be reclamined from the sea in early 1980.
