This paper constructs a user experience map of Meituan Takeaway and applys mapping to indicate the inner relationship between the system and service scenarios, which sheds light on the improvement of services optimized by user experience. The paper elaborates on the step-by-step procedures for drawing a user experience map and uses the Meituan Takeaway service as an example for visually illustrating how users’ interaction behaviors, actual thoughts, and emotional changes occur over the whole course of service through a user experience map. This approach can accurately quantify the user experience from a globalized perspective and seek out its factors. Combined with the pain points and opportunities from the Meituan Takeaway user experience map, specific optimization strategies are proposed at three levels of service process, service function, and service environment. The above strategies provide a new way of thinking and approach to the research about the optimization of user experience and service of Meituan Takeaway. It will also help improving the user experience of online food ordering platforms and contribute to the optimization of services on such platforms.
