User Interface Design of P2P Lending Mobile Application Using Design Thinking

The maturity of mobile technology made market transaction activities to be shifted online. This cause the development of a good user interface to become more important due to the power of a first impression in gaining a potential customer. This paper presents a detailed, step-by-step user interface design for a peer-to-peer lending mobile application called Minjemin. This is done using a well-known iterative process called Design Thinking, which is implemented to ensure a good design compared to not using any methodology. The paper will explore each step (microcycle) of Design Thinking while also describing how to implement the related design methodologies for each step. The proposed designs were tested by more than thirty testers to ensure removal of bias and resulting in a design that is satisfactory according to the Maze Prototype Usability Score and System Usability Scale scores.
