This study was empirically performed to demonstrate the development propensity and quality of the public software projects in Korea. Tile sample employed in this study contains 168 auditing reports on 107 public software projects which were carried out in the period of 1998 to 2003. The important findings of this study can be summarized as follows. The quality issue in the development process is getting more important with the lapse of time. In addition, the importance of end users' conveniency increases from year to year. Although the Pareto Principle(20 : 80 principle) is not applied strictly, most problems are caused by a few items. Finally, we find evidence that the overall Quality of public softwares is positively influenced by the information system auditing.

In accordance with the growing importance of software in computer systems, software quality and performance has become a hot issue in all computer-related fields and businesses. But the measurement and evaluation of software quality still poses a problem, due to the different viewpoints of software developers and users. This study attempts to combine the external characteristics of quality representing the viewpoint of users, and the internal characteristics representing the viewpoint of developers of quality. In order to do this, this study provides multiple models which select the appropriate internal characteristics which reflect user requirements from earlier phases of development. The goal of this study is to enhance the applicability of 40 internal characteristics of ISO 9126 to the models.

Nowadays, as the importance of SOA-based software is recognized, the market of SOA-based software is getting bigger. In response to this, the requirements about high reliability and quality SOA-based software is getting increased. In this research, we clearly suggested the evaluation method by giving a specific evaluation example to evaluate the quality of SOA-based software. It is expected to raise the objectivity and the utilization by inducing the quality improvement from this research.

The construction industry consists of various and massive architectural information as an architectural process includes a variety of design stages with cooperation of many disciplines. A Building Information Modeling (BIM) serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. building SMART has developed Industry Foundation Classes (IFC) standard for interoperability of BIM based information. Several software tools are already IFC-compliant. However, there are a lot of problems related to efficient interoperability of software owing to the lack of guide regarding the software usage and insufficiency IFC interfaces of software. The purpose of this study is to suggest efficient IFC support interface development methodologies of existing IFC certified software. The scope of this study is interoperability test for open BIM based quality assurance. To achieve this purpose, the authors have classified subject of open BIM based quality assurance and investigated IFC certification process and certified software. In addition, the authors have exported and imported via IFC files using different IFC interfaces in the software for interoperability of architectural objects and their properties. Finally, the authors have suggested IFC support interface development methodologies and hereafter direction for efficient interoperability of IFC certified software based on open BIM.

This paper focuses on realizing design improvement and high quality through visualization of reverse engineering-based software. As new technologies and complex software emerge in various areas of the fourth industry in the future, software verification with both stability and reliability is becoming an issue. We propose a reverse engineering-based UML design extraction and visualization for high-quality software ranging from simple computational software to machine learning-based data-oriented software. Through this study, it is expected to improve software quality through design improvement by checking the accuracy of the target design and identifying the code complexity.

This study was exploratively performed to demonstrate the management behavior of the public software project in korea. In this study, 167 auditing reports on the public software project which were carried out during $1999{\sim}2003$, were employed and surveyed. Survey reveals that quality management was the most neglected in process of software project management relative to other 12 management areas. And configuration management, risk management, time management, and scope management follow up in order in its vulnerability in software project management.

To achieve software quality and human-centred design for electronic ship navigation called e-navigation, an international guideline of software quality assurance and human-centred design was approved in 2015. Usability is a common goal of both software quality assurance and human-centred design as developing e-navigation system and software developments. Therefore, research is needed to evaluate the usability of e-navigation systems and software such as metrics that can use usability testing. This paper derives effectiveness metrics for e-Navigation usability testing based on international standards. The research method is to analyses and compares the effectiveness measurement and metrics in ISO 9241-11 for human-centered design and ISO/IEC 25022 and 25023 for software quality to find out measurements and metrics being defined commonly. The derived metrics are applied to Electronic Chart Display and Information System as a case study based on performance standard.

The interest in software defects is growing. Companies are working on reducing them by various ways with a software development part, customer service part and quality management part. The defect data collected from them will be analyzed according to the condition and purpose to minimize the defect, and it will contribute to improving the quality of products. This study analyzed the software defect progress for companies based on the test maturity model, and set up the defect preventing process. They were applied to the project, and the number of defects decreased from 106 to 16. This study focused on the existing defect, which is a basic requirement for software quality management, and have importance by presenting a way to improve the software product quality with minimum resources.

Today, the use of the open source software is rapidly increasing. But, it is also true that the quality aspect of the open source software is not being considered seriously enough. As we see, the future prospect of the open source software seems to demand the development of a set of quality assessment technology for the open source software due to the current status of quality problems and sustained growth in its usage. Therefore, in this study a set of open source assessment models are analyzed to establish evaluation criteria, with which the open source software are to be evaluated.

In this paper, we consider possibility that the multiple errors occur in each testing stage. At present, software reliability modeling is considered as a part of software reliability quality assurance in software engineering. However they dealt with the software growth model for the single error debugging at each testing stage until now. Hence it is necessary to study software reliability with multiple errors debugging. Therefore we propose software reliability growth modeling and estimate the parameters in the proposed software reliability growth model for the multiple errors debugging at each testing stage.
