<![CDATA[The procurement system for goods and services in hospitals requires the support of quality applications so that the vendor management and procurement process can take place efficiently and transparently. In the implementation of the Vendor Management System (VEMANIS) at RSAB Harapan Kita, several operational problems were still found, such as inconsistencies and delays in updating vendor information, as well as inconsistent system responses in supporting the procurement process. These conditions indicate the need for system quality evaluation based on user perceptions. This study aims to analyze the effect of website quality on procurement effectiveness using the WebQual 4.0 approach which includes three main dimensions, namely Usability, Information Quality, and Service Interaction Quality. The research method used was quantitative with data collection through questionnaires to 100 VEMANIS system users. Data analysis was carried out using SPSS through validity tests, reliability tests, classical assumption tests, and multiple linear regression. The results showed that Information Quality (p = 0.030) and Service Interaction Quality (p = 0.001) had a significant effect on procurement effectiveness, while Usability* (p = 0.127) did not show a statistically significant effect. These findings indicate that the quality of information and service interactions within the system play a more dominant role in supporting procurement process effectiveness than ease of use. Therefore, improving the quality of information updates and the reliability of system service interactions are priority factors in the development of VEMANIS to support a more effective procurement process in the hospital environment.]]>
