  • Source code quality is very Important that software embedded into product is difficult to change. In order to improve source code quality, it should be considered the quality of analysis and design models as well as the quality of source code. In this paper, we suggest 'Practice Pattern' as one of practical techniques to improve embedded software source code quality. Practice pattern is a procedural pattern to guide modeling and coding activities in software development phases. We believe that applying our pattern provides the improvement of optimum performance, modularization, and portability for embedded software source code.

  • Recently, many software companies are trying to improve the software quality and project outcome with more costs and efforts in development time. In the software convergence and integration environments, it is required efforts to gain high quality of software. In other words, it is required to utilize software engineering knowledge and technology for higher software quality and better software project productivity. The Software development productivity can be varied by software process capability according to building a framework for software development, selection and use of appropriate technology, human resource management. Software process capability will influence software project outcome which is the general opinion. This study provides empirical evidence about software engineering efforts and investment approach to lead software project performance. We measured the software engineering efforts by SW engineering level and analyzed the corelation between software engineering level and schedule deviation. And, we verified that this performance is affected by the size of software company. As a result, software process capability is important to build a infrastructure and develop systematically software project. The higher software engineering level can lead to improved software project performance.

  • As modern weapon systems have evolved into embedded software systems, the capability to develop, install, and maintain high-quality software products is becoming increasingly valuable in today's competitive aerospace and defense industry. It is desirable, especially for government-contracted projects whose end-users are military personnel, that specific types of software quality elements are assured early during product development; namely, functionality and usability. Motivated by this need to approach improving software quality from a user's perspective, this paper presents a case study that analyzes system-level software integration testing results for a weapon system indigenously developed in the Republic of Korea. Quantitative data, such as software defect ratios and configuration change rates, are computed to observe meaningful trends with respect to functionality - represented by tests designed to verify the system's electrical signal interfaces - and usability, which is evaluated in terms of how often the initial human-computer interface had to be re-designed. Insights gained from these exercises are subsequently presented as a set of "lessons learned" to take into account when developing new software items for complex weapon systems.

  • As the area of software application is increased. the software is becoming larger and more complex. In addition, development of the high quality software within the limits of the budget is strongly demanded. Many methodologies, such as software process improvement, object-ori-ented development, requirement-engineering, and software metrics have been introduced in the software development process in order to attain such objectives. Among those techniques. Requirements-Engineering gives basic guideline to develop high quality software. In other word. in order to develop high quality software, requirements should be elicited, and described. And with proper reviews and management. the quality of requirements can be improved. In this paper, quantitative measurement method that is based on IEEE Std-830-1998 for the require-ment-specifications is proposed.

  • In this paper, we propose a method for estimation software quality in terms of software test data, and it is necessary to predict the period of time required for software test evaluation. We need a model to understand of estimation of software quality. In this paper, we propose a model to estimate the number of days for software test using the data obtained through the tester's sex, and present a model for analysing the number of errors according to six quality characteristics by software type.

  • Because of formlessness and sightlessness of software, sytematic quality management is hard to implement. But we attemped collective quality management as hardware production by configuration management and settled on software quality management standard outlines. We are implementing efficient quality management by software quality management according as these standard guidelines. In this study, we study error management supporting functions as an attempt of development of software quality management supporting system which can support quality management activity by reduction and early finding of error input, and represent various visual output elements which can help error management supporting functions. And we represent the background of construction of this software quality management system and searched effects which we can get when we use the error management supporting function.

  • Software quality is classified by quality of process and product. In experience of Quality Management, it is known that quality level of product as it depends on goodness and badness of process and organization. As a result, improvement of software process has been important subject. According as this trends, ISO 12207 is publicated as standard of software life cycle process by ISO. For UML based object oriented development process, it is necessary that we should research detailed definition of activity and task of ISO 12207 process which is added, deleted or tailored in according to organization and project characteristics. In this thesis, by according with ISO 12207 software life cycle process, UML based object oriented development process is proposed. This process is composed of 7 steps and 19 activities including development phase, activity and product to improve quality of reliability. Usefulness of object oriented process for improvement of software quality is proved at three ways, which are comparative analysis of process characteristics, SPICE process evaluation and SPICE rick analysis.

  • So far, various researches have been conducted on evaluation of e-learning software, but subjective evaluation criteria are formed according to the classification presented from the viewpoint of the researcher rather than systematized form according to related standards. In addition, standards for software evaluation are continuously being supplemented for practical use, so it is urgent to establish evaluation bases by establishing evaluation criteria. Therefore, in order to establish the quality evaluation standard of e-learning software, this study analyzes the quality requirements of e-learning software based on the usability system among the quality characteristics of ISO/IEC 25000 series. This evaluation standard is distinguished by the fact that the evaluation standard of e-learning software that reflects the latest trend of related standardization has been established and practical utilization has been improved. It can be used effectively for quality evaluation and certification of e-learning software in the future.
