The objective of the present study is to analyze the relationship of suppliers and customer participation in product development process and effects of such participation on product innovation since it is getting more and more weight in manufacturing companies. It is also aimed in this study to explore if business performance of manufacturing companies might be affected by the suppliers participation as well as product innovation that is realizable by such participation. From the analysis, following conclusions could be drawn: First, suppliers participation in manufacturing companies turned out to have influence upon product innovation (standardized coefficient=0.193, C.R=3.510), implying that nothing is more important than the role of suppliers who have intention to realize innovation through participation in manufacturing companies. Second, the analysis showed that customer participation exercised impact upon product innovation of manufacturing companies (standardized coefficient=0.686, C.R=6.433), suggesting that the more customer participate in product development process of manufacturing companies, the more manufacturing companies could sharpen their competitiveness. Third, it was made known from the analysis that the product innovation thanks to suppliers and customer participation in manufacturing companies could have influence upon their business performance (standardized coefficient=0.762, C.R=7.666), signifying that the product innovation of manufacturing companies might depend on the participation of suppliers and manufacturers and, in turn, could affect their own business performance.

In this study, we focus on identifying the determinants of improving technology collaboration performance between buyer and supplier and the impact of the determinants on new product development performance. We adopted trust, control and information sharing as the determinants of technology collaboration and the frequency of new product introduction and ratio of new product on revenue as dependent variables. We conducted hierarchical regression and mediation analysis using the data collected from 600 Korean manufacturing firms by Korean Productivity Association and Ministry of Trade and Industry in 2012. The empirical findings indicate that trust, control and information sharing are positively associated with technology collaboration performance and the degree of technology collaboration is also positively associated with both new product development performance. In addition, new product development performance is not only affected by technology collaboration but also mediated by trust. This result implies that developing social capital, trust with partner play a important role in leading to better performance by open innovation.

The purpose of this study is to find empirical relationship between PL activities and firm performance. Five categories of PL activities and three performance measures were examined. Using a sample of 135 companies, we found that activities related to TQM practices and manufacturing defect had significant impacts on all three measures of performance. Activities related to design defect, warning defect and sales partially influenced performance measures. The result suggests that performance could be maximized by the mutual organic combination of the product safety efforts with the overall process from design to sales.

Success in new product development is vital to most industrial firms. In recent decades, a firm's new product strategy is incresinglyrecognized as an essential component of the total corporate plan in developing countries. In this research, 81 Korean manufacturing firms are examined to identify the relationships between a firm's product innovation stratege and the performance results with special emphasis on firm size in a developing country. First, a total of 8 strategy dimensions were identified, which constitute the specific elements of firm's innovation strategies. Two independent dimensions of performance were also identified and were found to be closely linked to the strategy adopted. Then, a categorization scheme is developed to distinguish firms according to their size, and proves useful in performance results might be altered for different company size. The findings generally suggest that a well-balanced new product program emphasizing both marketing and technological effort appropriately is needed to make the program successful. The different size of the company is found to call for somewhat different strategy dimensions to enhance the performance results.

Purpose: In developing new products, reducing performance variation is important for competitiveness factors such as quality, cost, and delivery. This paper aims at evaluating three performance variations; measurement, performance evaluation, and manufacturing variations, and then improving product and process design, focused on paper helicopter making case study. Methods: For measurement system analysis, gage R&R (repeatability and reproducibility), linearity, stability are evaluated. Since gage R&R are not satisfactory, the measurement system is improved by adopting voice memos application of iPhone and providing standard measurement procedure. To evaluate performance variation, product deterioration and environment factor (wind speed) is considered. Since the existing design is sensitive to these noise factors, a new product design is developed, which is proven to be robust to the noise factors. Finally, manufacturing variations are evaluated with five factors which can cause variation in flight time. To reduce the impact of three significant factors, three improvement methods are applied. Results: Three performance variations are evaluated and robust paper helicopter design is presented. Conclusion: To reduce measurement and process variations, improved measurement method and paper helicopter making procedure are proposed. A new product design is also presented which is robust to deterioration and environmental variation. This paper is expected to benefit students and practitioners who want to have hands-on knowledge on new product quality improvement.

The rapidly changing business environment requires small and medium-sized suppliers to develop creative new products. Therefore, many previous studies have attempted to identify important factors for successful new product development. However, despite the importance of firm learning has generated considerable interest in new product development, the central issue of firm learning remains unanswered. Therefore, this study investigated the effect of adaptive learning of small and medium suppliers on creativity and new product performance in new product development. As a result, it was confirmed that adaptive learning positively affects both novelty creativity and meaningfulness creativity. On the other hand, meaningfulness creativity has a positive effect on new product performance, but novelty creativity has no effect on new product performance.

A continuous development of new products is the lifeblood for firms that hope to maintain competency in competitive environments. Ongoing success in these environments is dependent on whether the management can choose or can't chose the proper mix of new product development strategy, new product development process, and organizational structure. Rather than considering the interrelationship among these success factors, however, most previous studies of new products development have examined these issues individually. Moreover, because past research has been unidimensional in nature, there is a lack of knowledge about how new product development strategy, process, and structure could be linked up each other. Consequently, we have no complete perspective of the linkage among new product development strategy, process, structure, and performance. The purpose of this study is to examine the new product development strategy, process, and structure of firms, and explore the effect of each on performance as well as linkage among strategy, process, strategy and structure.

This study investigates the extent to which product innovation is associated with firm performance, and how this effect is moderated by other type of innovation efforts. Empirical analysis is conducted (1) to determine the effect of product innovation on firm performance; (2) to explore the moderating effect that process innovation, organizational innovation and marketing innovation activities each has on the relationship between product innovation and firm performance. The analytical sample comprises a total of 816 Korean manufacturing firms from the 2010 KIS (Korean Innovation Survey) data and merged with financial data from KIS Info for acquiring the objectivity. The results show that product innovation is positively associated with a firm performance. Product innovation when combined with higher levels of process, organizational and marketing innovation activities resulted in higher firm performance. The results suggest that product innovation is a decisive factor of firm performance. More importantly, process, organizational and marketing innovation activities support product innovation and thus impact firm performance indirectly. In addition, this study examines the effect of innovation activities on firm performance by different firm size and R&D intensity, thereby further improving the details of this study.
