현재 우리나라 신발산업은 고객만족을 최우선 목표로 삼고, 내부프로세스 개선의 활동을 통한 원가절감과 생산성 향상에 집중하고 있다. 이에 비해 외부와의 정보공유를 위한 노력은 기울이지 못하고 있는 실정이다. 이로 인해 산업전체가 하나의 유기체와 같이 움직이지 못하게 되어 시너지 효과(synergy effect)를 창출하지 못하고 있다. 이에 본 연구진은 이러한 문제를 해결하기 위해 신발업체가 생산과 관련한 다양한 정보를 공유함으로써 산업 전반적인 효과를 거둘 수 있도록 하는 비즈니스 모델을 개발하고자 하였다. Now, the Korean footwear industry needs the concrete enhancement of its competitive edge for regaining of its previous well known reputation. For this purpose, this study emphasizes the cooperation between the members through the supply chain of korean footwear industry, as a c-SCM (Collaborative Supply Chain Management). In this study, at first we analyze the traditional structure of supply chain in Korean footwear industry and find out critical problems which are the main barriers against its efficiency and potential competitiveness. And then, we develop the collaborative structure to resolve these problems through the system design of supply chain and finally we suggest the c-SCM business model consists of several collaborative process modules for the Korean footwear industry. The procedure of this system modelling follows the system design methodology with the empirical way through field trips of the relevant industry and depth interviews with practitioners as well as with analytical way. The proposed c-SCM business model provides the collaborative procurement and production plans of footwear manufacturing, and it will support a mutual-supplementary reliance relationships among members of its supply chain. In this way, the enhancement of the efficiency and competitiveness can be expected through the synergy effect of coordination of information and material flow, the reduction of lead times, and production costs.

Korean semiconductor industry became a leading international producer within a short period of time as a result of surviving cut-throat competition with producers from industrialized countries. As the electronic industry began approaching the saturation stage, however, Korean manufacturers faced such difficulties to keep up the current competitive position as lack of the structural adjustments in product lines and relevant technology innovation. In order to restore the competitive edge in Korean semiconductor industry, the fundamental strategic change are required such as restructuring of the main production lines and reconstruction of global management network. Korean semiconductor manufacturers need to consider the consistent adapting of advanced technology in relevant areas, and the expanding of global operations through FDI by taking advantage of the accumulated memory products technology and success. European countries, in particular, have the considerable values for Korean manufacturers` global operations, such as the well developed R&D programs, the superior technology of telecommunications and electronic devices, and the geographical advantages for global management networks. This study provides the strategic scheme of cooperative tie with European semiconductor industry to increase competitiveness of Korean industry. It suggests the strategic global operations in Europe by consorting with European R&D programs like JESSP, MEDEA, GRESSI, IMEC. Also it shows the supportive operations tactics in order to get the efficiency and effectiveness of FDI in Europe. Based on the previous case activated by one of the Korean semiconductor companies, it`s strategy and practice are analyzed and the strategic suggestion is provided in practical way.

As the speedy change of business environment, the Korean shipbuilding equipments industry is practicing the manufacturing innovation with the new technology for the global competitiveness. Adoption of ERP in this industry is the one of the cases. Although the industry is eager to grab the edge of the competitiveness, the implementation of this new technology shows the poor performance often. It is due to the operational gap between the characteristics of shipbuilding equipments industry and the built in standardization process in ERP system. The shipbuilding equipments industry does mainly OEM business with shipbuilders, in fact, its process is under lots of volatile conditions, such as non standard items, customer order changes, and due date changes, etc. Without fine tuning and practical adjustment, the process in standard ERP system will not work properly and its performance is to be very limited. This research analyzes the mis-implementation of the ERP in a shipbuilding equipments company and shows the redesign details for the effective ERP performance, along with as-is, to-be BPR process focusing on sales process.
