As modular production becoming increasingly widespread in globalized manufacturing industries, sub modules or parts of the final product are being provided by many suppliers. Some part suppliers design their own products for themselves. In some cases, part suppliers provide the same type of product to multiple OEM companies. Because all part suppliers and OEM companies typically cannot use the same CAD system, engineering change in the CAD model of one company cannot be directly propagated to related CAD models of other companies. Even if two companies use the same CAD system, it may be difficult to share their CAD model owing to corporate security policy. In this paper, a neutral reference model that consists of a neutral skeleton model and an external reference data model is proposed as a new medium for the sharing and propagation of engineering change information among collaborating companies.

As the modular production is an important issue in globalized manufacturing industries, sub modules or parts of the final product are provided by many suppliers. Some part suppliers design their own products for themselves. In some cases, part supplier may provide the same type product to multiple 1-tier companies. Because all suppliers and 1-tier companies can not use the same CAD system in general case, the engineering change in the CAD model of one company could not propagate to related CAD models of other companies directly. Although they use the same CAD system, it is hard to share their CAD model with each other because of company security policy. In this paper, the neutral reference model, which consists of the neutral skeleton model and the external reference model, is proposed to apply a global top-down modeling approach to collaborating companies.

Small and Medium-sized Enterprises (SMEs) are being faced with rapid changes in their business environments due to evolution of technologies and innovation in societal eco-systems. Particularly, dynamic interactions between such environments and enterprise activities have become significant, so technology planning, which is a process of identifying appropriate directions regarding product and technology development, has received much attention to cope with such dynamics proactively. However, SMEs typically have limits in performing independent, strategical and systematical technology planning activities due to the lack of human, material and financial resources. This paper proposes the development of a product roadmapping method so that SMEs carry out efficient technology planning activities with interconnections of external business environments. The present work provides product roadmap templates that directly accommodate the influence of business environments on the product's system and its associated super/sub-systems with the use of external environment analysis techniques including TRIZ methodology, PEST and 5Forces analysis. These templates are useful to efficiently forecast the directions of product's development and evolution, which arise from changes in external environments. Consequently, the present work enables SMEs to flexibly cope with the era of the next R&D generation, which pursues value creation through mutual interconnection between business environments and technology development.

This study examines the differences in the various characteristics of the firms along their growth stage based on the survey data of 2,515 Korean ventures. Venture characteristics include KSFs(Key Success Factors), environment attributes of their product markets, CEO roles, the use of OPR(Other Peoples Resource). Growth stage of the ventures are classified by their dominant management problems: foundation, the market launch of the first proprietary product or service, The Outset of second generation product or service, and the Initial Public Offering (IPO) and stabilization. The results of this study show substantial differences in many aspects among firms at different growth stages. Although common KSFs exist, KSFs are changing as the venture evolves. Differences in KSFs and environmental attributes along growth stage require CEO to do different role in business process. Different kinds and amounts of external resources are needed according to their growth stage. However, almost all of external resources are offered to ventures in later stage. Entrepreneurs need to change their role, as their firms grow, from visioning and strategic role to marketing and production emphasized role. Based on the results, this study suggests a number of new government policies and future research ideas. Other implications and limitations of this study are also noted.

The economics of big data knowledge, especially cloud computing and statistical data of consumer preferences, has attracted increasing academic and industry practitioners' attention. Firms nowadays require purchasing not only external private patent knowledge from other firms, but also proprietary big data knowledge to support their new product development. Extant research investigates pricing strategies of external private patent knowledge and proprietary big data knowledge separately. Yet, a comprehensive investigation of pricing strategies of these two types of knowledge is in pressing need. This research constructs an overarching pricing model of external private patent knowledge and proprietary big data knowledge through the lens of firm profitability as a knowledge transaction recipient. The proposed model can help those firms who purchase external knowledge choose the optimal knowledge structure and pricing strategies of two types of knowledge, and provide theoretical and methodological guidance for knowledge transaction recipient firms to negotiate with knowledge providers.

본 연구에서는 IT융합제품 구매 결정에 있어 잠재 구매자들이 어떻게 외부 정보를 활용하는지를 대표적 IT융합제품인 스마트폰 사례를 중심으로 살펴보고 있다. 외부 정보 원천 (external information)의 활용이 중요시 되는 이유는 스마트폰과 같은 신기술 기반의 융합제품이 더 이상 제품 사양만으로 차별화되는 탐색재가 아닌 사용자 인터페이스, 애플리케이션 이용 등으로부터 체득한 경험정보가 더욱 중요시되는 경험재적 성격을 포함하기 때문이다. 기존의 연구에서는 이러한 신기술 기반의 제품 선택에 있어 지인들이나 일반소비자들의 구전이 중요한 역할을 하는 것을 검증하였으나 온라인, 오프라인을 통해 다양한 정보 원천의 영향력을 비교 검증하는 실증 연구는 거의 없었다. 본 연구에서는 기존 연구를 참조하여 외부 정보 원천을 기업광고, 지인집단, 전문가집단, 일반소비자집단, 언론매체로 구분하고 이러한 외부 정보 원천이 어떻게 스마트폰의 구매 결정에 영향을 미치는 지를 정보 원천의 속성, 정보의 품질인식 측면에서 실증 분석하였다. 특히, 잠재구매자의 자기조절초점(self-regulatory focus)에 따라 정보 원천에 대한 속성 인식과 각 정보원천으로부터 발생한 정보에 대한 품질 평가에 차이가 존재함을 밝혔다.
