This research employs a case study of a professional dental medical equipment company in Taiwan, cites the theoretical basis of innovation diffusion, and uses the design-thinking double-diamond model to review the company's history of promoting digital IOSs in the market from ground zero. Integrating the theoretical foundations of medical institution procurement and innovation diffusion, this study finds that different target customers have very different perceptions and acceptance of new technologies. The knowledge and attitude of medical personnel are the primary factor affecting new technology procurement, only then will decision-making factors such as financial, functional, and service aspects be further considered.
