This paper presents preliminary results from a larger project led with the French company Auxivia. The latter offers a smart drinking glass (SDG), supporting monitoring daily water intakes of elderly people and helping identify residents to encourage. Contexts and work organizations can deeply differ from a nursing home to another and can impact the use of the SDG. Based on a comparison between two nursing homes, we unveil the impact of both work organizations on the integration of technology requirements. We discuss the results by providing recommendations to improve the integration of SDGs in various work organizations.
