디자인 의사결정 과정의 보조 평가척도 개발

Design decision-making in the product development process is a critical process that determines the product exterior and structure, which influence product marketability factors such as design, usability, and manufacturing cost. However, the selection of the final design in design decision-making relies heavily on the experience and intuition of evaluators. Design principles and standardized tools are difficult to apply to design decision-making, and decisions are usually made by qualitatively analyzing opinions from designers, engineers, clients, and developers. This study has made an attempt to develop a detailed evaluation scale to assist the qualitative decision-making process, which currently involves experience and intuition. The attributes of the product development process and design decision-making were examined through a literature review, and designers were surveyed on how the processes identified in the literature are being applied in their practice. In design decision-making, the most important evaluation indicators of product exterior were found to be aesthetics, uniqueness, symbolism, and harmony, while those of function were functionality, usability, safety, and durability. Based on these indicators, this study developed a detailed evaluation scale for design decision-making.
