Innovation level in set-based design: an integrated approach with chosen-to-fit and custom-to-fit solutions

Set-Based Design (SBD) is superior in risk reduction, knowledge creation, and innovation. However, its implementation demands more resources than traditional strategies. Thus, it is crucial to balance design space size and available resources to disseminate SBD. This paper proposes a method to define the level of innovation of subsystems enabling a hybrid development strategy, integrating the SBD and the Point-Based Design (PBD). We undertook a research action in a technological innovation design subject to significant knowledge and human/financial resource restrictions. The team allocated most resources in the SBD and focused efforts on critical subsystems. The exploratory and scientific nature of SBD enabled learning about the product without prior knowledge for supporting decision-making. By presenting the state-of-the-art regarding innovation level in SBD and proposing a method to define the level of innovation and a hybrid development strategy, this research paves the way for SBD in projects with significant resource restrictions.
