Recently, as most functional business activities in an enterprise are supported by computerized information systems, data duplication and inconsistency among functional information systems become serious problems. It brings people to have many interests on data quality management. This paper presents a case study in which a company had improved their data quality by enhancing their data quality management processes. Though the case study, we describe main issues and risk factors in the process of data quality improvement projects as well as solutions to resolve the issues, which can be referred by other companies who pursue data quality improvement. Also, the improvement effects are evaluated by multidimensional perspectives which include quantitative and qualitative measures on data quality, productivity, customer satisfaction, organization, and culture.

Supplier Relationship Management (SRM) is a strategic partnership activity for an enterprise and is expected to be a significant performance element in the current enterprise environment where uncertainty is growing. Despite the effective SRM allows companies to manage quality and inventory throughout their logistics procurement process with their suppliers and increase the profitability of the company, there is a scarce of theory about supplier relationship management (SRM) and many companies are not aware of the importance of SRM and depend only on simple electronic purchasing methods. Therefore, I analyze the H Company as a case company, which is a large domestic company and has reached 2,500 domestic and overseas suppliers. SRM process and its effects are evaluated as (1) Purchasing strategy division 2) Process division (3) IT infrastructure division. By analyzing SRM as one of the management strategies that bring the overall value of enterprise performance up, and by looking at how domestic large corporations manage their suppliers, I hope that manufacturers with many suppliers will recognize the importance of SRM and build an SRM tailored to their business.

소프트웨어 프로세스 개선에 대한 원리와 방법은 CMM/CMMI 와 같은 프로세스 모델의 등장으로 인식하였으나 개인과 팀 차원에서 이를 구체적으로 구현하기 위한 운영적 차원의 절차와 수단의 부족으로 실제현상에 적용하여 성과를 창출하기에는 어려움을 겪어왔다. 이러한 문제를 해결하고 개발자와 개발팀의 차원에서 CMM/CMMI 의 목표와 프랙티스를 구현하기 위해 SEI(Software Engineering Institute)에 의해 PSP/TSP 가 개발되었다. 그러나 RSP 가 팀 차원에서 스프트웨어 개발에 사용할 수 있는 구체적인 기법들을 기술하고 있더라고 RSP 에서 수집되는 메트릭에 대한 분석기법은 여전히 부족하다. 따라서 TSP 수행시 발생할 수 있는 문제를 방지하고 프로세스가 변경되고 유지 관리될 수 있도록 하기 위해서는 식스시그마의 다양한 통계 기법과 의사 결정도구의 사용이 필요하다. 본 논문에서는 TSP 의 각 스크립트에 식스시그마의 통계 기법과 의사 결정도구를 포함 시킴으로써 TSP를 확장한 식스시그마-TSP 통합 프레임워크와 활용 가이드라인을 제시함으로써 팀 차원에서의 프로세스 개선의 수행을 지원하며 팀 차원에서 발생할 수 있는 이슈를 식스시그마의 분석, 정량화 도구를 사용하여 해결하고 아울러 팀 성과를 향상할 수 있는 방법을 모색해본다.

Military vessels are complex weapon systems consisting of various integrated onboard equipment. Since their acquisition of military equipment takes a long period of time and a prototype ship is deployed and tested, vessel development has relied on its proprietary process. However, due to the growing complexity of onboard equipment technology, application of systems engineering (SE) process has become indispensable. Nonetheless, an effective design process complementing the existing design with the SE has not yet been developed. As such, we have studied an improved basic design process for submarines based on SE. To do so, we analyzed the processes for the basic design, technical review, and requirement management. Included reviews and requirements are SRR, SFR and PDR, and SSRS, SSS, and SSDD. By combining the results in the SE framework, we built an improved basic design process that can be applied in parallel with the SE-based technical review and requirement management. To assess the process, we applied our proposed model to the submarine development undergoing the basic design phase. It is possible to effectively manage the requirements, design artifacts and improve traceability, and also utilize them as test and evaluation materials. The SE-based basic design process is expected to be useful in other kinds of vessel design.

Employment in enterprises is a consecutive decision-making process based on the results of their innovative activities and it is necessary to consider this relationship as well explicitly in an analysis of the employment performance through technological innovation. Based on this critical mind, this study would analyze the structural relationships among enterprises' innovative activities, the performance of technological innovation, a compensation system and the creation of employment, reflecting the correlation of the process of the actual technology management performed simultaneously, utilizing the seemingly unrelated regression(SUR) model to estimate a simultaneous equation in addition to analyzing the relationship between technological innovation and the effect on employment with the ordered logit model to estimate a single equation as in the preceding studies. As a result of the analysis, a structural relationship could be found out, in which the execution of the compensation system would increase the performances of technical development and technology commercialization, which in turn, accelerates enterprises' employment. Especially, it is judged that enterprises' employment performance increases when technological innovation is managed from a process perspective in that the commercialization performance, as well as technical development, acts as a kind of hurdle in the effect on employment.

This study aims to implement an efficient process management system for small and medium sized(local) construction companies and a performance management system for the Korean construction industry. The process management system by Lean Construction is Web 2.0 platform-based and creates clusters with numerous general contractors and sub-contractors, which will enable mutually organic process management. Plus, this system will enable them to compare project performance management by analyzing it during or after a project by collecting and accumulating lots of data occurring in pursuit of a project. These performance management cases will be of help in process planning during similar upcoming projects. This study is expected to somewhat reduce the burden of implementing a complicated process management protocol and system that Korean small and medium sized (local) construction companies experience with their web-based process management, and is supposed to realize accurate performance management with highly reliable data which are significantly accumulated within the database.

ITA법 제정 이후 많은 공공기관들이 ITA/EA 도입 및 구축을 추진하고 있으나, 명시적인 성과를 보여주는 경우는 많지 않은 것으로 조사되고 있다. 특히, 공공기관 EA 성숙도 수준 평가 결과 EA 도입에 비하여 관리 및 활용 영역의 수준이 낮게 나타나고 있다. 본고는 EA의 활용성을 저해하는 제 원인 중 EA 관리체계의 부실에 주목하였다. EA 도입과 함께 EA관리 체계가 수립됨에도 불구하고 EA 관리 및 활용 수준이 낮은 이유는 첫 번째로, EA관리 조직 설계 시에 EA 산출물의 작성 주체 및 협업 방안이 구체화되지 않은 상태로 관리 조직 및 역할이 수립되는 경향을 지적할 수 있다. 두번째로 EA 관리체계 설계 시에 각 EA 산출물의 특성이 고려되지 않은 획일적 관리 프로세스의 설계로 인하여 관리체계가 오작동하는 문제를 지적할 수 있다. 본 연구에서는 이러한 문제의식을 근간으로 개별 산출물에 대하여 요구되는 정확성과 정합성 수준에 따라 범정부 EA 산출물들을 구성도/정의서(Diagram/Description)형, 모델(Model)형, 정보자동생성(Auto Description)형, 설계서(Description)형, 서지정보(Metadata)형으로 유형화하고, 각각의 산출물 유형에 따른 조직의 역할과 협업 방안, 관리 프로세스를 제시하였다. 본 연구를 통해 향후 EA 관리체계 수립 및 조정 시에 산출물 유형별로 작성 주체 및 관리 조직간 요구되는 역할과 관리절차를 명확히 함으로써 효율적인 EA 산출물 관리가 이루어지도록 하고, 이를 통해 궁극적으로 EA 활용도 증진 및 EA의 근원적 목적 달성이 가능할 것으로 기대한다.
