Presently, electronic (e-) procurement system is crucial for buying and selling supplies, and services between the government and individuals over the online environment. E-procurement is one of the Business to Consumer (B2C) applications that has the benefits of reducing transaction costs and supplier's payment with increased information quality and accuracy of system. Nonetheless, users are still facing difficulties in using the e-procurement system thus causing them to feel dissatisfied. Moreover, studies related to user experience (UX) and e-procurement systems are also lacking in terms of UX interaction with this system. Users also face the problems such as lack of transparency and efficiency, corruption, and complicated procedures. There are other barriers faced by them such as prejudice, resource constraints and lack of experience. Therefore, this study aims to identify quality requirements of the e-procurement system which enhance their user experiences. This study uses a qualitative method (open-ended interviews) for data collection. The selection of the participants was done through purposive sampling and analyzed using a qualitative data analysis tool. The results revealed from interviews, that there are seven quality requirements that are important namely, effectiveness, efficiency, satisfaction, security, user interface aesthetics, ease of use and learnability. This study will be useful for system developers, and designers to put emphasis on these quality requirements for better user experience in enhancements of e-procurement in the future.
