Today’s business entities are required to achieve their business benefit in alignment with the pursuit of social-good value as SDGs show. This case study presentation will explain our experience of collaborative design of social value to action to solve the social problem. We designed socialized will of participants through Philosopher Kant’s Conative (Future vision), Affective (Stakeholder value) and Cognition (Articulated requirement) combined with the open agile business design Takumi method. We will explain how we externalized participants’ internal thoughts as explicit knowledge from three of Kant’s views and collaboratively make it common and socialized and what outcomes were achieved through this process.
