With progressions in technology and high demand for value, business model designs based on cooperative systems are essential for innovative manufacturing servitization. Previous studies, which focused on product innovation or specific industries, either lacked standardized steps or promoted inconsistent processes and tools. Therefore, an integrated, holistic evaluation for designing and using service design methodologies was essential. Examining previous research, this study derived key factors categorized through focus group interviews with 13 experts. The analytic hierarchy process was used to derive weights for each factor to rank the level of importance. The results revealed the key factors of service design methodology: utility, systematicness, innovation, and convergence. Lower factors included the applicability to reality, ease of use, representation of needs, composition feasibility, customer value scalability, industrial convergence, flexibility, output clarity, collaboration support, and business improvement. The results of this study may be used as a basis for the development and selective adoption of service design methodologies in macroscopic terms. The study provides a direction for innovation and improving business models. It also serves as an academic foundation for industrial service innovation and ecosystem creation.

Human centric lighting (HLC) is a promising market for innovations in the lighting market, but there is a lack of research on sustainable business models. Therefore, this study proposes a service, ecosystem, business model, and platform to innovate the HLC industry using eco-science methodologies suitable for manufacturing servitization. The study’s findings show that the introduction of a platform-based B2B smart space service can have an impact on the spread of HCL. Accordingly, this study derives a business model and billing strategy that industry stakeholders involved in the smart space can cooperate with. Further, the study proposes a platform design to realize the proposed business model and verifies a service prototype to analyze the completeness of the research results and their economic ripple effects. As for the implications, this study presents an integrated perspective business model to revitalize the HCL market based on a systematic methodology from the convergence studies perspective. Additionally, there are academic implications that, instead of just proposing the research results, objectively evaluate and verify the completeness of the results. The results of this study suggest a future-oriented direction for the field of HCL.

The purpose of this study is to design a business model that generates profits by developing eco-friendly convergent products. This study proposes a new concept of solar signage in the digital signage system that helps carbon emission reduction. This study developed a solar signage business model using the eco-science methodology specialized in manufacturing servitization. Following the ecosystem platform service strategy (EPSS) framework of eco-science optimized for convergent industry service design, this study implemented service derivation, convergent ecosystem definition, and business model development. The developed business model was evaluated by 10 experts in the field. The business model obtained 43 points, which exceeded the standard commercialization decision cutoff of 35 points. This study’s results imply that the business model is developed from an integrative perspective and defines the convergent industry ecosystem, a convergent knowledge service methodology, in digital signage. Moreover, through the business model, the perspectives on technological development can be expanded and the model can play an important role in carrying out new industry commercialization based on convergent technologies.
