Evaluation of the Integrated University Information System at Universidad Técnica del Norte Using the DeLone and McLean Success Model

This study aims to evaluate the Integrated University Information System (SIIU) at Universidad Técnica del Norte by applying the DeLone and McLean Information Systems Success Model. The SIIU plays a crucial role in academic management by integrating key modules, such as executive, faculty, and student portfolios. Despite its long-standing implementation, a comprehensive assessment of the system's performance and its impact on academic activities had not been conducted until now. The research specifically focuses on assessing the SIIU's impact from the students' perspective, applying the six dimensions of the DeLone and McLean model: system quality, information quality, service quality, use/intention to use, user satisfaction, and net impacts. Four assessments were carried out over two years (May 2022, February 2023, July 2023, and July 2024), using a 28-item survey to measure these dimensions.The findings confirm the validity of the DeLone and McLean model in evaluating information systems and reveal a positive trend in students' perceptions of the "SIIU – Student Portfolio" over the past years. The results also provide a detailed breakdown of the system's strengths, weaknesses, and areas for improvement, as experienced by students. These insights offer valuable guidance for the SIIU management team, facilitating targeted improvements to optimize the system’s contribution to the university’s academic environment.
