User interview


We went to the German Cross Red of Schwäbisch Gmünd and had an initial conversation with the director. We got an overview of the current transportation system. And we have experienced different types of vehicle ordering and knew about the holistic service. During the process, we listed all important roles and make interviews with them to find their pain points and needs.

Filter & Sort

Based on interviews of all roles in the workflow, we did a whole user journey including user groups, touch points and important actions. Many problems are found, especially the collaboration between the coordinator and drivers. 


We analyze our main user groups, what pain points are, what breaks down their works, what the current solution is, what they want to improve, why can't improve them now...

A test verifies the status of Wi-Fi as well as other related data, including canal, frequency and suggestions.





After listing high priority requirements and user stories, we clarify what features we should focus on the limited time. The information architecture helps us to get an overview of the whole picture. The low fidelity wireframe is a good and quick way to prove some design points.  After the wireframe of main screens is done, we did soon the first user test.
