<![CDATA[Web-based information systems are increasingly becoming integral to organizational operations, making the evaluation of system quality and user acceptance essential. This study aims to identify and synthesize approaches for integrating the Extended Technology Acceptance Model (TAM) with operational quality indicators in the evaluation of web-based information systems through a systematic literature review. The study employed a Systematic Literature Review (SLR) following the PRISMA 2020 protocol, covering 15 scientific articles published between 2019 and 2026 and retrieved from Google Scholar, Scopus, and IEEE Xplore. The selected articles focused on studies applying the TAM or Extended TAM with at least one operational quality indicator. The review findings show that the constructs of perceived usefulness (PU) and perceived ease of use (PEOU), along with external variables such as system quality, information quality, and service quality, consistently have significant effects on system acceptance and use. Integrating the Extended TAM with the DeLone and McLean model and the ISO/IEC 25010 standard provides a more comprehensive evaluation framework than using a single model. Three integration patterns were identified: sequential, parallel, and holistic. These findings suggest the development of an integrated evaluation instrument that incorporates both user acceptance dimensions and operational quality indicators to enhance the effectiveness of web-based information system evaluation.]]>
