In order to improve software quality, it is necessary to efficiently and effectively remove software defects in source codes. In the development field, defects are removed according to removal ratio or severity of defects. There are several studies on the removal of defects based on software quality attributes, and several other studies have been done to improve the software quality using classification of the severity of defects, when working on projects. These studies have thus far been insufficient in terms of identifying if there exists relationships between defects or whether any type of defect is more important than others. Therefore, in this study, we collected various types of software defects, standards organization, companies, and researchers. We modeled the defects types using an ANP model, and developed the weighted severities of the defects types, with respect to the general application software, using the ANP model. When general application software is developed, we will be able to use the weight for each severity of defect type, and we expect to be able to remove defects efficiently and effectively.

소프트웨어 제품의 품질을 보장하기 위해서는 제품을 개발하는 단계에 미리 결함율을 예측하여 원하는 수준의 품질을 확보하는 것이 중요하다. 결함은 사용자의 요구사항이 제품으로 구현되고 기능에 대한 테스트가 수행되는 단계에 가장 객관적이며 정량적으로 관리될 수 있다. 따라서 본 논문에서는 통합테스트에 대한 계획을 수립하는 단계에 제품에 대한 결함율을 미리 예측하여 제품 결함율이 조직의 관리범위에 들어올 수 있도록 통제하는 결함예측모델을 제안한다. 조직의 제품 결함율 베이스라인을 설정하고 통합테스트 결함율에 영향을 미치는 변수들과의 회귀분석을 통해 통합테스트 결함예측모형을 구축한다. 또한 제품 결함율에 영향을 미치는 변수들과의 회귀분석을 통해 제품 결함예측모형을 구축하고 결함예측모형을 활용해 제품 결함율을 분석 및 통제한다. 본 논문에서 제안한 결함예측모델은 실제 프로젝트에 적용하여 실효성을 검증하였으며 제품이 완성되기 전에 결함율을 예측하여 통제할 수 있게 함으로써 소프트웨어 품질을 향상한다.

The organization and company's effort to improve software qualify contributes to the increase of software productivity and quality in some sense. However, it has not been a solution of root causes. This result is caused not because of people or technology, but process in-stitutionalization. Recently SQA (Software Quality Assurance), which provide mechanism to make sure that the software development process and products follow the assigned requirements, plan and standards, is applied to achieve the quality improvements. Several standards and models are developed for SQA activities. However, those standards and mode]s are written in form and do not provide information related to the detailed procedures, methods and outputs. Therefore, the organizations that want to adopt those models or standards have to put a lot of effort to acquire the knowledge about the models and to set up SQA Process that is tailored to meet organization's goal and objectives. In this research, we developed SQA support package to support the organization to develop their SQA process in more convenient and systematic ways. With this package, the organizations can establish SQA Process by tailoring those features necessary to reflect organization's characteristics. We expect this package contribute the organizations in a way that it reduce the effort and cost for establishing SQA process.

무기체계의 대형화 및 복잡도가 증가함에 따라 무기체계에서 소프트웨어의 비중이 큰 부분을 차지하고 있으며 이로 인해 소프트웨어 결함에 따른 잠재적인 위험성도 증가하고 있다. 무기체계 분야에서는 무기체계 소프트웨어 개발 및 관리 매뉴얼을 통하여 개발 단계별 활동 및 검토사항들을 정의함으로써 단계별로 소프트웨어의 품질을 확보할 수 있도록 하는 한편, 소스코드 내의 잠재적인 결함을 체계적으로 제거하여 품질을 높일 수 있도록 소프트웨어 신뢰성 시험 제도를 도입하여 운영하고 있다. 본 글에서는 무기체계 소프트웨어 신뢰성 시험 현황에 대하여 소개하고 발전방향을 제시하고자 한다.

정부는 공공데이터의 품질 관리를 위하여 공공데이터 품질관리 수준평가를 진행하여 공공데이터 품질을 관리하고 있다. 파일 형식의 공공데이터를 진단 시 품질진단 담당자가 대량의 파일데이터를 필드명과 필드 내 데이터에 의존하여 수작업으로 도메인을 판단하여 진단한다. 때문에 품질진단의 정확성을 신뢰하기 어렵고 진단에 많은 시간이 소요된다. 본 논문은 파일형식의 공공데이터 품질진단의 정확성을 확보하고 진단 소요시간을 단축하기 위해 데이터 분포 통계를 이용한 CSV 형식의 공공데이터 도메인 판별 모델을 제안하였다. 제안된 모델을 적용하면 공공데이터 품질의 정확성을 향상하고 진단 소비 시간을 단축시킬 것으로 기대된다.

Though any method in various software development methodology is selected and used in performing IT project, there are quite a few problems in applying it to the project environment, thus customizing effort as a reasonable method is continuously demanded. Therefore, the study attempted to track a basic frame formation process of quality management model applying the software development methodology based on SDLC that is widely used. The study analyzes and modelized an empirical cases of a financial company that is relatively highly rated by expert groups through a variety of trial and error and continued supplementation for it for a long time. And in addition to it, it analyzes cases of public institute project, derives problems, and also proposes a guideline related to creating artifact.

For high-quality software development, it is necessary to detect and fix the defects inserted. If defect management activities are not properly performed, it will lead to the project delay and project failure due to rework. Therefore, organizations need to establish defect management process and institutionalize it. Process standard models handle defect management in the area of project monitoring and control. However, small organizations experience difficulties in implementing and applying defect management process in a real situation. In this paper, we propose a defect management process for small organization which is designed in accordance with the characteristics of a small projects such as few participants and short development period. The proposed defect management process will be based on a tool chain with open source software such as Redmine, Subversion, Maven, Jenkins that support a defect management process and SW Visualization in systematic way. We also proposed a way of constructing defect database and various methods of analyzing and controlling defect data based on it. In an effort to prove the effectiveness of the proposed process, we applied the process and tool chain to a small organization.

The guideline on software quality assurance and human-centered design for e-Navigation was approved as IMO circular June 2015. e-Navigation software systems are characterized by a high proportion of data quality and quality in use. The purpose of this paper is to improve the quality in use of the maritime software quality assurance for the safety route guiding service. In this study, we added the stage which the stockholders such as a project manager, software developers, and end-users use the prototype that was developed based on the scenarios before the stage of design and development. Through this, we could review the requirement about the quality in use for a limited time at the beginning of the project. also we could raise understanding the concept of this project and goal system.
