【 摘 要 】

Small and Medium Sized Micro Business (UMKM) owners often experience difficulties in running their business. UMKM needs real-time access on its transactions in order to properly oversee its business endeavors. This study was aimed to overcome UMKM restriction by taking advantage of disruptive era advancement through the development of a web-based UMKM point of sale software application named PayPOS. To do this, we carried out two iterations of user experience (UX) study parallel with the development of transaction and inventory modules. The UX study utilized the Lean UX method and applied mid-fidelity prototype interfaces and cognitive walkthrough to measure its usability metric efficiency and effectiveness. In the meantime, the transaction and inventory modules applied to the incremental method. Here, the development of the transaction module was divided into four increments: basic transactions, sales transactions, repair and maintenance orders, and transaction reports. Whereas the development of the inventory module was divided into two increments: inventory management and purchase order. On the first UX iteration, the success rate was 72%, whereas, on the second iteration, the success rate was 78%. The overall success rate on tasks tested was 92% which indicated that UX outcomes were easy to use. Further, upon modules integration completion, the PayPOS developed was successfully tested using the Black box method. The user acceptance test carried out also indicated that PayPOS exhibited an attractive interface, easy to understand, and suitable menus and submenus. Hence, the employment of UX study results in the development of PayPOS has helped facilitate business owners in managing their business processes.
