These days, many companies use information systems as a basis for organizational management activities and as an important component of sustainable management. Thus, securing and operating a high-quality information system that can improve the efficiency of business processes is a large part of corporate competitiveness. In order to get such a critical information system, it is only possible to successfully carry out the project. Various attempts and studies have been undertaken to increase the success rate of the project. However, the reality is that the success rate is still not getting much better. In this study, the concept of quality of service, which has long been actively studied in marketing area, was applied as a new factor to enhance the project's success. In this study, project performance activities were defined as the act of providing services. A survey of 164 valid collection data was analyzed. The analysis used SPSS 23. Four process quality factors (customer participation, customer response, knowledge and skills, reliability) and 21 metrics were derived. Through this research, I hope to be the starting point of applying process quality concept as a new breakthrough to increase success rate of project.

Global sourcing strategy is the one that apparel firms adopt in order to improve efficiency. Souring statesgies are not limited to the decision of sourcing country or vertical integration of sewing process Sourcing strategies include all the ecision of marketing process from the acquisition of fabric to distribution of products. The present study aims to analyze the soucing strategies of Korea apparel industry in global perspectives by applying transaction cost approach and aims to provide the implications for the future. The results are as follows ; (1) sourcing strategies in the dimension of domestic versus offshore soucing are determined by the experience in foreign business and the degree of fashionability of the product. (2) Firms tend to increase affshore soucing as they accumulate the experience in foreign business because they can decrease transaction costs as the perceived risks decrease (3) Also firms tend to source their products in foreign countries when the products are more fashionable. Brand loyalty of the product is a additional factor that increases the proportion of domestic sourcing. (4) Degree of vertical integration of sourcing is determined by the fashionability brand loyalty and the experience in foreign business. That is firms decrease the transaction costs by avoiding the investment to short life fashion products. However firms increase the control over the high reputation product by in house production. As the apparel firms tend to more marketing oriented and the national boundaries of business envrionment becomes permeable more efficient global sourcing strategies should be stablished, Besides the production costs nonproduction costs should be equallly considered in order to analyze the total costs.

The paint removal of fighter jets is just as important as the painting, because perfect paint removal ensures the quality of the exterior painting on the aircraft. However, the current conditions for paint removal work of the ROKAF's are poor. It is identified that the painting process currently implemented by the ROKAF is not only exposed to harmful compounds such as harmful dust and hexavalent chromium, but also consumes a lot of water. Thus, the introduction of advanced facility is considered. This study compares the fighter jets painting removal process currently applied by the Korean Air Force with the improved laser coating removal process of the US Air Force, and conducts an incremental analysis to perform economic analysis for the introduction of advanced facility. Four scenarios were envisioned on the premise of an increase in the number of fighters in the future, incremental analysis shows that laser coating removal method is advantageous in all scenarios. In addition, it is recommended that paint removal cycle keeps the current 12-year and the outsourcing amount to civilian depot is reduced.

외국 IT선진 기업들은 비용절감, 우수인력 활용, 전락 시장에의 접근 등의 목적으로 해외 IT 아웃소싱은 물론, Business Process Outsourcing(BPO)도 활용하고 있다. 선진 글로발 기업들은 이미 우수인력을 선점하여 글로발 차원에서 경쟁력을 유지하고 있다. 비롯 늦었지만 최근 우리나라 IT 서비스 기업들도 해외에 개발센터를 설립하여 중국인력을 활용하기 시작하였다. 개발 인건비 절감이 주 목적이나 분산 원격개발의 프로세스를 정립하고 훈련하는 것도 부수적으로 기대하고 있다. 중국시장을 접근한다는 장기적 전략으로 현지회사와의 M&A, 교육 및 보상체계 제공, 사용 언어의 다변화 등을 통하여 우수인력의 적극 확보하는 것이 요구된다.

BPR은 1990년대 초에 제안되어 많은 기업의 경영 혁신 도구로 선택되어 왔다. 그러나, 대다수의 기업이 성공적인 결과를 보여주고 있지 못하고 있는 실정이며 Champy는 BPR의 실패 원인으로 '경영 패러다임의 변화 없는 경영 혁신'을 들고 있다. 본 논문에서는 BPR의 한계를 극복하고 프로세스 효율성을 극대화할 수 있는 경영 혁신 기법으로 BPO(Business Process Outsourcing)를 제안하고, BPO 품질 관리를 위해 전략적 6 시그마의 DMAIC를 활용한 SLA(Service Level Agreement) 적용 방법론을 제안하고 있다. 아웃소싱 품질을 관리하기 위한 근본적인 요인을 정의하고 이에 대한 산포 관리와 목표 수준 관리의 2단계를 반복함으로써 아웃소싱 품질을 높일 수 있을 뿐만 아니라 궁극적으로는 기업의 전체 프로세스 효율성도 극대화할 수 있을 것이다.

In smart grid, electricity consumption data may be handed over to a third party for various purposes. While government regulations and industry compliance prevent utility companies from improper or illegal sharing of their customers' electricity consumption data, there are some scenarios where it can be very useful. For example, it allows the consumers' data to be shared among various energy resources so the energy resources are able to analyze the data and adjust their operation to the actual power demand. However, it is crucial to protect sensitive electricity consumption data during the sharing process. In this paper, we propose a fine-grained access control scheme (FAC) with efficient attribute revocation and policy updating in smart grid. Specifically, by introducing the concept of Third-party Auditor (TPA), the proposed FAC achieves efficient attribute revocation. Also, we design an efficient policy updating algorithm by outsourcing the computational task to a cloud server. Moreover, we give security analysis and conduct experiments to demonstrate that the FAC is both secure and efficient compared with existing ABE-based approaches.

In late 90s, organizations recognized the information technology as an key enabler of the business strategic accomplishment which lead them heavy increment on IT investment. These organizations tried to hold the competitive advantage by focusing on their core competency. And these acts raise their interests on IT outsourcing. Recent trends of the organizations concern on evaluating the effectiveness of the previous IT investment and the reasonable selection on IT investment type. Also, the objective evaluation of the service level and continuous improvement are major concern of the outsourcer. Consequently, interests on Service Level Agreement (SLA), an immanence operating tool for managing the level of the information system service objectively and qualitatively, were raised among IT outsourcing service providers, outsourcers, and operating departments. Yet, only a few domestic conglomerates adopted the SLA, and exact usage of the SLA is currently unknown. Because of the importance of the SLA between a service provider and an outsourcer, the agreement is treated with high confidentiality. This raised the problems to both the private and public organizations, are considering the SLA, with absence of concrete guide line to internalize SLA management process. This study provides the organizational and environmental factors of the adopting and applying the Service Level Agreement (SLA) by conducting multiple case research. The sampled companies are currently implementing the SLA over 1 year of usage period. Factors were used to provide the operational contribution for implementing the SLA. The study also provides the effects on IT performance through the SLA. For this, in depth interview was conducted for each sampled company. As a result, if SLA between outsourcer and service provider can be used as an immanence operation tool and actively implemented, SLA will be an strategic tool for various decision making in IT management practice with long term relationship, better shared partnership, and continuous service improvement.
