Sustainable Design of Takeout Product Service System of Milk Tea Drinks in Chinese University Campus Based on KANO Model

While milk tea drinks have gradually become the trend of consumption among young people, the consumption of disposable tableware such as milk tea cups and straws has brought great pressure to the environment. This study is aimed at Chinese university campus user groups. We first set up the product service system diagram, and clarified the relationships and interactions among the various stakeholders in the system. Then, we created the service blueprint and user journey, and used the Kano model to comb the user needs and the touch points of product and service system. Finally, we found the opportunities to optimize the system and explored the sustainable construction of the takeout product service system of milk tea drinks in Chinese university campus.
