Adamson University has a diverse community where students are engaged in different activities in line with their academic field and extra--curricular activities. There are three types of student organizations in the university;; academic, socio--civic and religious. These organizations are collectively known as Recognized Student Organizations (RSOs), administered by the Office for Student Affairs (OSA). This office oversees all organized events together with Physical Facilities and General Services Office (PFGSO) for the venue reservation and approval. The aforementioned offices are currently using the traditional pen and paper method for event processing. The main goal of this research is to develop an Online Venue Reservation System that can be used to manage and process event data and help reduce problems encountered, such as data redundancy, data loss, and excessive paper use. The study used qualitative research wherein qualified respondents from OSA, PFGSO, and RSO’s were chosen using purposive sampling. This developed web application allows different users to request, monitor, and approve or disapprove a venue reservation request as well as generate reports when necessary. The website was evaluated using ISO 25010 Software Quality Model by the target respondents. The survey showed that the developed system was assessed as “Good” in terms of functionality suitability, performance efficiency, compatibility, usability, reliability, security, maintainability and portability. In terms of compatibility, the website was rated “Fair”. Furthermore, the respondents also evaluated the website as “Highly Feasible” in terms of technical, operational, economic and environmental considerations.
