The expansion of the online market is expected to change the purchasing environment. The purpose of this study is to examine the difference in the moderating effect of each characteristic on perceived quality and purchase intention according to the group according to product involvement and purchaser age. The first step is to identify the characteristics of online information sources and social media platforms through a literature review. Next, when perceived quality affects purchase intention, we verify the moderating effect according to the characteristics of online information sources and social media platforms. The moderating effect is verified at the stage by dividing it into a group according to product involvement and a group according to age. The following results were confirmed throughout the study: First, perceived quality significantly affects purchase intention. Second, in the relationship between perceived quality and purchase intention, the influence of the moderating effect is different depending on the high-involvement product and the low-involvement product. Third, it was confirmed that there was a difference in the moderating effect of online information sources and social media platforms in the relationship between perceived quality and purchase intention according to age. This study intends to increase consumers' purchase intentions by identifying specific age groups and product groups of involvement and establishing strategies suitable for the characteristics of online information sources and social media platforms.

Platform-based product family design is recognized as an effective method to satisfy the mass customization which is a current market trend. In order to design platform-based product family successfully, it is the key work to define a good product platform, which is to identify the common modules that will be shared among the product family. In this paper the clustering analysis using dendrogram is proposed to capture the common modules of the platform. The clustering variables regarding both marketing and engineering sides are derived from the view point of top-down product development. A case study of a cordless drill/drive product family is presented to illustrate the feasibility and validity of the overall procedure developed in this research.

본 연구는 제품디자인의 콘셉트 개발에 있어서 개념적이며 비시각적인 콘셉트를 플랫폼 기반의 구조적 접 근을 통해 구체화시키고, 디자인 경영자원의 분배와 활용에 대한 전략적 구조로써 플랫폼의 효용성 제고(提 高)를 통해 향후 디자인 경영자원의 분배에 대한 전개방향을 제시하는 것에 목적이 있다. 이를 위해 디자인 콘셉트가 어떻게 적용되었는지 제품디자인의 유형별 사례조사를 실시하였고, 디자인 콘셉트가 구체화 된 사례에 따라 분류 하였다. 이 분류 된 사례를 통하여 플랫폼의 구조를 정의 하였다. 사례 연구를 통해서, 디 자인 콘셉트는 플랫폼 기반의 다양한 구조를 통하여 구체화 되고, 구조화 된 플랫폼을 통하여 계획 된 기업 또는 제품의 아이덴티티가 형성된다는 것을 알 수 있었다. 따라서 기업의 경영철학, 슬로건, 심볼, 서비스, 기술력, 디자인 등의 세분화 된 플랫폼 기반의 제품디자인에 서는 디자인 경영자원을 계획하고 부서간이나 프로젝트에 따른 동일한 분배보다는 기업 전략에 따른 선택 과 집중을 위한 합리적이고 효율적 분배가 적절하게 이루어 져야 할 것이다.
