  • We need to measure the quality of each module to assess software quality. Especially, in industry, it is important to measure quality of modules quantitatively in order to improve bad modules and reuse good modules. In this paper, we define moduleness as characteristic that modules should be possessed and propose a method to measure software moduleness quantitatively. A case study conducted in this paper shows the usefulness of the method by measuring and evaluating moduleness of modules based on open source software developed by C, C++ and Java languages.

  • This paper illustrates a prototyping framework of the documentation-standards retrieval system via the data mining approach for enhancing software development quality. We first present an approach for designing a retrieval algorithm based on data mining, with the three basic technologies of machine learning, statistics and database management, applied to this system to speed up the searching time and increase the fitness. This approach derives from the observation that data mining can discover unsuspected relationships among elements in large databases. This observation suggests that data mining can be used to elicit new knowledge about the design of a subject system and that it can be applied to large legacy systems for efficiency. Finally, software development quality will be improved at the same time when the project managers retrieving for the documentation standards.

  • There is a new trend of incorporating software coverage metrics into software reliability modelling. This paper proposes a coverage-based software reliability growth model. Firstly, the failure rate function in coverage is analytically derived. Then it is shown that the number of detected faults follows a Nonhomogeneous Poisson distribution of which intensity function is the failure rate function in coverage. Practical applicability of the proposed models is examined by illustrative numerical examples.

  • The types of industrial software are classified into package, embedded and system type. The Package type software means industrial ERP, the embedded software is built in industrial devices and the system type software controls the manufacturing and production system, In this paper, we described about the development of evaluation modules which can implement quality test and evaluation fur industrial embedded software. If you are planning to enhance the objectivity and the validity of evaluation modules, it is necessary to construct the system based on international standard. There are two international standard, ISO/IEC 12119 and ISO/IEC 9126 related to quality evaluation of software. Also ISO/IEC 14598-6 is the standard that defines the construction form of the evaluation modules. Based on these standards, We extracted the quality requirements of industrial embedded software and constructed the evaluation modules that can evaluate the content level of the quality requirements.

  • Recently use of embedded software has been increased to different areas. The requirements and demands for the embedded software have also been altered. In the past, the embedded system was used in simple task and small portable devices but now, the usage of the embedded software has expanded to do much more complex and precise actions in a variety platform environment. The embedded software enables multiple softwares to be integrated into one and at the same time, control it. Currently the biggest challenges embedded software is facing during its development process is the improvement in product production and quality assurance. Our research team has developed an embedded software based on the component (technology or methodology) which both improves production capabilities as well as quality. Additionally, we also established and constructed a reliability test system which can effectively test the quality of the developed embedded software to further increase its competiveness.

  • Recently, it's increasing to use the applied technology related to the quantitative and qualitative growth of industry area. One of them is software to be used in industry area, and software is the most important part in using the industrial equipments. Therefore, the quality of software in the industrial devices determines the performance of the devices. At this time, it's inspired an evaluation and measurement of software quality to have within industrial equipment, and it's forming the research and development in domestic and foreign. In this paper, we constructed evaluation metrics based on ISO/IEC 12119, the International Standard for the general requirements of software and ISO/IEC 9126-2, the International Standard for the evaluation of software qualify characteristics and sub-characteritics, and for this accomplishment, It has been designed and developed industrial software international standard compatible approval system which approve a quality based on quality test result of industrial software using the ISO/IEC 14598-6 that international standard for organization of evaluation module.

  • Recently, the progress of smart phone market has retarded by oversupply therefore wearable computer has been the focus of new growth engine. Wearable computing system is a complex fusion of a variety of technologies such as wireless network, embedded, sensor and new material. Because these technologies involves utilization and mobility in addition to quality characteristic in existing software, application of ISO/IEC 9126 is not perfect when assessing quality of wearable computer. In this study, author suggested new quality assessment model for wearable computer by sorting quality attribute in ISO/IEC 9126 and adding new quality attribute. For this, author investigated features and functional requirements related to wearable computer. and then author suggested quality standard and metrics by identifying quality characteristic. Author confirmed practicality of quality assessment model by using suggested model in scenario and comparing quality assessment of three goods such as company S, L, G. This quality assessment model is expected to use guidelines for assessing quality of wearable computer.

  • As software projects become larger and more complex, we need to take a more systematic approach to quality assurance. One plausible approach is the use of SQA (software quality assurance) methodology. Since this SQA methodology was not available, our study presents a SQA methodology. This methodology has a repository in which a set of quality assurance tasks with their related techniques and deliverables is defined and from which one can select only appropriate tasks based upon characteristics of project. This study further suggests a rule-based approach for supporting task selection process.

  • Today, the growth of software industry leads to e quantitative expansion of software package products. Due to this rapid increase of software package products, qualify certification has been required fur software products which users select. Unlike the quality certification of industrial products, the history of software product certification has not been so long. For this reason, software quality evaluation and certification methods have not matured yet. When certifying software products, one of most important factors is the systematic generation of evaluation sets. The evaluation sets include checklists with metrics, and criteria for the software quality certification according to the classification of software product type. This paper presents a metamodel for the systematic generation and maintenance of the evaluation sets. Then, we construct prototype level evaluation sets to show the validity of the metamodel.

  • 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.
