Many researches have concluded that product advantage or superiority is the most important factor for the commercial success of new products. However, the specific dimensions of product advantage have not been studied as yet. Based on a survey of newly introduced products in recent years, we suggest the eight dimensions of quality of new product: function, time, limitation, usability, problem prevention, economy, maintainability, nativeness. The dimensions and their constituents are explained with examples.

System engineering(SE) management techniques applied for space launch system development are introduced to assess the current status and address the effwctiveness of these techniques. Management plans and guides are prepared for the work breakdown structure , data, comfiguration, interface control, Quality assurance, procurement, reliability, risk and verification/validation . Further improvement is required for the system engineering management plan(SEMP) to merge the international cooperation into current engineering managment system.

In this paper, I investigate the impact of quality management activities on the public sector within the framework of Malcolm Baldrige (MB) national qualify model. The Structural Equation Modeling approach has been employed to investigate the cross influences among the seven MB categories. This empirical study shows that a number of statistical hypotheses are significant. The leadership category is the most important driver among the quality management activities. This, in turn, implies that the main source in quality management is to foster a solid qualify oriented leadership system. Categories such as Information Analysis, Strategic Planning, Human Resource Development and Management, and Process Management are significantly related to the Customer Satisfaction category. In addition, leadership, Information Analysis, and Customer Satisfaction categories ere significantly influential to Management Performance.

This Purpose of this paper is to suggest the effects of success factors of six sigma on the management performance. This dissertation deal with key factors that led to successful implementation through existing literature. Therefore, this major success factors of six sigma revealed performance of cost reduction and improving quality. This study is empirical analysis the effects of six sigma performance of cost reduction and improving quality)on the management performance(profitability, growth, market value). The results of this study, six sigma quality performance turns out to have positive(+) effect on the all management performance.

Purpose: The purpose of this study is to escape from the existing defense quality policy focused on government-led quality assurance for mass-produced items and to secure quality reliability of weapon systems through a defense quality policy paradigm shift based on designing a verification systems anchored on reliability through the enhancement of military supply quality control in the development stage, the enhancement of quality responsibility of the manufacturing contractor and other methods. Methods: For the shift to the quality-based defense quality policy, the status and the problems of the status quo are analyzed and the direction of future defense quality policy is suggested based on literature review of the concept of reliability and reliability in the field of defense, on case studies of global corporations and their quality policies, on the background on quality assurance in defense, and on case studies of quality policies in other government organizations, Results: Based on the case studies of quality policies in global corporations and other government agencies, the importance of preventive quality control from the early development stages, quality control based on the reliability of the materials and parts, and shift of the quality policy to a certification system to achieve these objectives were highlighted. Conclusion: To secure reliability of weapon system quality, the quality policy must be shifted to a system focused on reliability-based design and verification and there is a further need to enhance the operational efficiency and capacity of DTaQ based on studies and evaluation of weapon system reliability.

The axiomatic hypothesis of the objective distribution of evaluation subjection will be proposed in this paper. On the basis of that, set up the random response model of the expert evaluation system and the quality control principle of expert base. Under this principle, develop the statistical quality control theory of expert base, further; provide the quality improvement technology for expert base.

As more and more companies pursue ISO 9000 certification, the adaptation of ISO 9000 has brought about some significant positive effects to domestic quality systems However, somenegative results occurred in domestic industries rushing to fulfill the requirements of these new quality systems. The primary objective of this research is to provide the efficient implemen tation process of ISO 9000 certification on the basis of total quality management concerning with ISO/ DIS 9000:2000, ISO/ DIS 9001:2000, ISO/DIS 9004:2000. this study has been conducted using the data collected from 325 Korean small and medium manufacturing companies which registered ISO 9000 certification in March 2000. The first, the adoption of a quality manage ment system needs to be a strategic decision of the organization. The design period of the adoption of a quality management system is influenced by the size of the organization, the products process, KS certification, the rate of management.

Purpose: The variation of the internal diameters of gun barrel incurs a lot of reworks in gun barrel manufacturing process and the significant quality problem of gun barrel. And it is likely to stem from the current measurement system for the internal diameter of gun barrel and the related manufacturing process as well. The purpose of this study is to improve the gun barrel manufacturing process through improving measurement system. Methods: The improved measurement system using laser can measure the internal diameters of gun barrel more accurately, and the properly adjusted honing process reduces the variation of internal diameters of gun barrel. Results: Comparing the mean square error of internal diameters for 6 gun barrels measured before and after process improvement shows that the variation of gun barrel internal diameters was significantly reduced after the process improvement. Conclusion: The introduction of improved measurement system for the internal diameters of gun barrel and the adjustment of related honing process results in the reduction of reworks of gun barrels and their internal diameter variations.
