Integration of Design Thinking in the Development of a Mobile Application for Property Sales Management

Abstract

The manual recording process in property sales is still widely used and often leads to issues such as information delays, data inaccuracies, and inefficiencies in unit booking processes. This study aims to design and develop a mobile-based Sales Property Management System as a digital solution to enhance efficiency and data accuracy in property management. The Design Thinking approach was employed as the primary methodology, comprising five stages: Empathize, Define, Ideate, Prototype, and Test. Data were collected through qualitative interviews with property sales personnel, revealing key challenges such as limited access to real-time information and reliance on manual transaction processes. Based on direct user feedback, the system was developed using an Agile approach, with React Native for the mobile interface, ExpressJS and TypeScript for the backend, and AWS cloud services to support system performance and scalability. Testing results indicated that the system successfully accelerated the booking process, streamlined workflows, and reduced dependence on manual methods. These findings demonstrate that the Design Thinking approach is effective in generating user-centered solutions and contributes significantly to the digital transformation of the property industry.
