Purpose: Recently, many quality issues are aroused in military forces, such as failures in K-series weapons, combat boots defects and 40mm ammunition explosion accident. To address these problems, the one and only government defense quality assurance agency, DTaQ(Defense Agency for Technology & Quality) tried to improve many quality assurance procedures and introduced new systems such as MRA(Manufacturing Readiness Assessment), TRA(Technology Readiness Assessment), and etc. However, as the amount of war supplies increasing every year, the resource(budget and manpower) for quality assurance is limited. Therefore, DTaQ had difficulty to handle the issue efficiently and effectively, and we propose the method to address this problem. Methods: The most popular quality assurance technique is a sampling method, in this research, we first review the many sampling techniques and compare the strength and weakness of each method. After then, we selected the most appropriate sampling techniques and applied the procedures in combat force support material and ammunition areas. Results: We can reduce the number of samples dramatically, thus the required amount of labor time and money can be saved. Also, the new sampling technique enforces the supplier to produce the product which meets the target value(desirable value). Conclusion: We can reduce the number of samples dramatically, thus the required amount of labor time and money can be saved. Also, the new sampling technique enforces the supplier to produce the product which meets the target value(desirable value). Lastly, since the new sampling method requires many numerical calculations, we developed a simple android OS smart-phone application which can be used easily in field.

Purpose: Classify quality assurance work for munitions as service quality attributes. And to derive service elements that need improvement to improve customer satisfaction through calculation of customer satisfaction coefficient. Methods: The quality assurance service for munitions is classified as service quality based on the Kano model through a questionnaire survey of workers in military service companies located in Busan and Kyung-nam areas. Investigate current customer satisfaction with service quality of defense quality assurance activites, and calculate customer satisfaction coefficient and potential customer satisfaction improvement index. Results: Identify current satisfaction levels for service quality of defense quality assurance activites and suggest service quality factors that should be improved to improve customer satisfaction. Conclusion: The service quality factor for the defense quality assurance service was classified into 13, and the customer satisfaction coefficient was lower than the satisfaction coefficient. When looking at the current level of customer satisfaction through the Potential Customer Satisfaction Index, attractive quality factors with PCSI indices were found to be necessary for service improvement.

Purpose: Defense government agencies in the world continuously try to improve operational efficiency in government quality assurance activities. The purpose of this paper is to propose some suggestions to enhance efficiency of government quality assurance (GQA) activities based on the analysis of the current quality assurance methods of advanced foreign agencies such as DCMA and NATO. Methods: In order to propose new directions, reviews and analyses are executed. (1) Former research results in Korea for enhancing GQA are reviewed, and their limitations are addressed. (2) Updated policies and procedures of the US DCMA and NATO are reviewed and their advantages are presented. (3) Current GQA policies and procedures are contrasted with those of US DCMA and NATO. Results: Suggestions for efficient Korean GQA activities are given in several aspects: GQA paradigm shift, clarification of GQA methods, facility-wide GQA, risk management for suppliers, counterfeit mitigation policy, data collection and control. Conclusion: Reviews on the government quality assurance policies and procedures of DTaQ, DCMA, and NATO are executed and compared with each other. The results of this research are expected to be useful guidelines to improve GQA policies and procedures in Korea, making it possible to realize more efficient GQA activities in Korea.

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.

국방기술품질원에서 1999년부터 수행중인 품질위험도 평가 기법은 하자발생 가능성이 높은 취약업체 또는 취약품목을 식별하는데 제한적이라는 평가를 받고 있다. 이 연구는 AHP 기법을 통해 평가요소의 중요도를 재 산정한 평가모형을 제시한다. 개선된 평가배점의 타당성을 검증하기 위해 2005년도 하자발생 품목의 위험도 평가결과에 적용하여 평가점수 및 위험도의 변화를 분석하였다. 개선된 평가모형은 기존의 평가배점 방법 보다 고 중 위험도 품목을 더 많이 식별해 낼 수 있었으며 업체위험도가 품목위험도보다 더 중요한 것으로 나타났다. 업체위험도에서는 전문능력과 생산실적, 품목위험도에서는 제품특성 평가요소가 상당히 중요한 것으로 평가되었다. 고 위험도로 분류된 업체는 품질에 있어 집중관리를 받게 됨으로 하자 발생의 가능성이 더 줄어들 수 있을 것이다.
