KaffeKuriren : Webbapplikationen som möjliggör kaffeleverans

This report examines how a peer-to-peer web application can make coffee more accessible to students at Linköping University. The platform allows students to order coffee from the university’s non-profit student café, Baljan, and have it delivered by fellow students. Making Baljan’s affordable coffee easily available can save students up to 30 minutes per trip and help maintain productivity between study sessions. Development focused on three key aspects: navigability, trust, and usability. The project followed a three-stage process: initial research that confirmed strong demand for a campus coffee delivery service; technical implementation produced a single-page web app using Flask for server-side functionality, along with Bootstrap, jQuery, and Stripe to ensure a responsive, dynamic, and secure user experience; and two rounds of user testing with five participants each focused on real-life tasks and were evaluated via the concurrent Think-Aloud protocol. Between iterations, improvements were mainly in design, transparency in the system, and navigation on the website. The result shows that the peer-to-peer delivery model is viable and appreciated by users. However, balancing simplicity, functionality, and perceived reliability presents certain challenges. Future work should focus on implementing identity verification and increasing trust mechanisms to enhance usability, trust, and promote broader adoption.
