In automobile industry, the depot (distribution center) system is utilized to adjust the inventory and to supply the demands to the firm timely. In case of the small lot demands of short delivery cycle and the long distance from the parts manufacturing to the firm, the depot system is very important. In this paper, a model to minimize the sum of costs of holding, inventory and transportation, is proposed to determine the optimal quantities of production and transportation in JTT system. Finally, computational results that verify the effectiveness of the proposed model are demonstrated.

Despite our extensive understanding on the Internet business and widely understood first-mover advantage. it is not clearly answered yet whether an internet firm can enjoy the first-mover advantage in the new environment of the Internet. This is mainly because the Internet marketplace itself has a complex combination of various business models, ranging from a simple channel-extension to a whole new business model. Based on new theoretical development on the first-mover advantage, we empirically test whether being an early mover in the Internet environment materially affects firm performance, using clickstream data from Korea where broadband Internet installation is ranked as top among OECD countries. Our results show the effectiveness of first-mover advantage on the web does not exist, regardless of its business model and competitive environment. This result expands our understandings on the e-business, not to mention of the real feature of first-mover advantage.

Knowledge transfer among employees integrates individual knowledge scattered within a firm, thus increases organizational effectiveness. In particular, the role of knowledge broker, which enables knowledge sharing across multiple teams or subunits, is critical for the success of knowledge management. This study classified the types of knowledge broker that facilitates knowledge flows among team, and examined the influences of various intra- and inter-team social networks. Survey responses from 128 employees of four R&D teams were gathered and analyzed using partial least square structural equation modeling. The results of analysis showed that all types of inter-team networks(i.e., emotional closeness network, frequency of interaction network, and perceived expertise network) had significant influences on related knowledge brokerage behaviors. In case of intra-team networks, only the emotional closeness network showed significant influence. These results proved the necessity of managing various types of intra- and inter-team networks to encourage knowledge brokerage behaviors within a firm.

As the necessity of customer relationship management (CRM) increases, measuring the performance of CRM have been actively discussed. Customer equity (CE) is regarded as an appropriate indicator for evaluating the outcomes of marketing activities. There are three drivers of CE: brand, value, and relationship equity. This study aims to investigate the impact of three drivers on customer satisfaction. Market competition is an environmental factor that affects the effectiveness of CRM. This study divides target firms into leaders and followers. This study found that the differential impact of CE drivers on customer satisfaction depends on the firm's status (leader or follower). Specifically, the brand equity driver significantly impacts the leader firm. However, the impacts of value and relationship equity drivers are bigger for follower firms. The above results suggest that firms need to build CRM strategies that consider the competitive situation of the market and their position.

Over the last few years Total Quality Management (TQM) programs have hem widely adapted by Korean manufacturing firms to improve their productivity, competitive edge and product quality levels. The purpose of this study is to evaluate the level of importance placed on four key TQM factors (customer satisfaction, strong management leadership, continuous improvement, imployee involvement and participation) used during the implementation of korean manufacturing TQM programs and to assess the effectiveness of those key factors in improving the performance of the firms. A Questionaire was developed and sent to senior managers in manufacturing organizations throughout korea. This survey asked qustions regarding 1) the firm's business environment and TQM program development 2) subcomponents of the key factors and 3) the effectiveness of the TQM program at improving the performance of the organization. The survey data were analyzed to determine the degree of correlation between each of the factors and the effectiveness of the TQM programs. This study demonstrated that the TQM programs were instrumental at improving the performance of the firms studied, and that the improvement was positively correlated with the length of time that the program had been implemented and the planned duration of the TQM program implementation. It was found that the person-oriented elements of management leadership and employee involvement were positively correlated and predictive of the success of the TQM Program, while the process-oriented components of customer satisfaction and employee involvement were not useful predictors of the effectiveness of the TQM program implementation.

Nowadays, many farmers use online management diagnosis tool developed by Rural development agency(RDA) for the purpose of self-diagnosis of their farm management. Database(DB) was created using the diagnosis results and has been used for agri-firm management consulting. However, the amount of diagnosis data in the DB has been decreasing year by year. This means that the diagnosis tool of RDA did not reach farmers' expectation. Therefore it is necessary to develop a practical consulting tool which is applicable for various types of agri-firm management. This study introduces a management diagnosis tool and consulting method based on multi-contingency organization theory and value chain model for the purpose of improving existing tools and methods. The consulting method based on multi-contingency organization theory shows the core strategy of agri-firms by two different ways such as "efficiency-oriented" direction and "effectiveness-orientated" direction. Also, this method emphasizes that the performance of firm can be achieved when subelements of firm activities follow the same direction with the orientation of core strategy. The important thing is the right firm management activity fitted to its strategic direction. Through this action, limited firm resources can be optimized. In order to make itself understand, this study shows a practical example applied by this method from actual agri-firms.

In this paper, we study the relationships between organization characteristics and desired software quality attributes of enterprise systems. We collected data from three client organizations in three different domains (auto manufacturer, insurance services firm, and government agency) that adopted enterprise software of the same software vendor. Our analysis discovers that capability is a more important attribute to the manufacturing and insurance firms than the government agency. Usability is ranked the highest among other attributes for the government agency and reliability for the manufacturing firm. The relationships identified in this study will help enterprise systems vendors predict their customer needs and, ultimately, increase effectiveness and efficiency in their software development processes. Such findings will be specially useful when software vendors develop enterprise software for a venture firm by enabling them to meet the customer needs customized by the organization haracteristics while staying within the incubating firm's limited budget.

The goal of supply chain integration is to improve the effectiveness and efficiency of supply chain in order to deliver customer value. So, the fit of between supply chain integration strategy and customer value strategy is very important. Therefore, this study explores the different types of relationship between supply chain integration and customer value, as well as in the firm performances. Cluster analysis is used to develop the typology of supply chain integration, and five typology (High Internal Oriented Integration, Medium Oriented Internal Integration, High Supply Chain Integration, High Customer Oriented Integration, Medium Oriented External Integration) are identified. Analysis of variance is used to test the relationship between supply chain integration typology and customer value, and firm performances. The results show that there are statistically significant differences in customer value and firm performances.

The importance of industrial policy and innovation policy perspectives on public procurement has recently been highlighted. In particular, there have been discussions and studies on whether public procurement directly affects the growth and innovation of SMEs. As an extension of this study, this study analyzes whether the age of a firm moderating the effect of public procurement on growth among the characteristics of firms participating in public procurement. The analysis data was constructed by matching the financial data of about 1,247 firms designated as excellent products by the Public Procurement Service(PPS) from 2006 to 2017 and the public procurement sales. As a result of analysis through the panel regression model, firms with a greater degree of public procurement showed a higher growth rate, and this relationship was stronger with younger firms. This result not only contributes to the existing academic discussion on the effectiveness of public procurement, but also has significance in the establishment of public procurement policy.

Purpose: Despite the fact that the majority of domestic firms are small in size, there have been few studies conducted to understand the leadership effectiveness of small firm CEOs. Based on the upper echelon theory, this study attempts to demonstrate empirically that transformational leadership of small firm CEOs can increase the innovative behavior of employees. In addition, the present study examines mediating effects of CEO trust perceived by employees when transformational leadership affects employees' innovative behavior. Methods: The survey data of CEOs'transformational leadership, innovative behavior of employees, and perceived CEO trust were collected from 176 employees working in domestic small firms. Hierarchical regression analyses were performed to examine the main effects between transformation leadership and innovative behavior and mediating effects of CEO trust perceived by employees. Results: The results show that CEOs' transformational leadership is significantly related to the innovative behavior of employees in the current sample. Results also indicate that CEO trust perceived by employees reveals a mediating effect in the process of transformational leadership affecting innovative behavior. Conclusion: The results show that as suggested by the upper echelon theory, the leadership of small firm CEOs can have a significant impact on positive job-related behaviors and attitudes of employees. The results also contribute to expand on the understanding of the relationship between transformational leadership and innovative behavior by explaining that transformational leadership can mediate trust in CEOs in enhancing employees'innovative behavior. Theoretical and practical implications are reviewed, and limitations of the study and suggestions for future research are addressed.
