This study aims to adapt and extend the DeLone and McLean Information System (IS) success model in the context of an online English as a Foreign Language (EFL) higher education foundation program. The objective is to enhance teaching, learning, and knowledge-sharing experiences within a virtual community of practice (vCoP). The research involved eight experienced full-time university lecturers with master's degrees in English language teaching as participants. They were presented with six openended questions followed by interviews. The study addresses the gap between research and practice by assessing the effectiveness of the model in measuring knowledge-sharing and user interaction within the EFL vCoP. The findings highlight the need for tailored models in specific online learning domains, such as EFL, rather than applying a generalized approach to education. The findings have practical implications for designing and evaluating online educational programs and communities, ultimately enhancing the quality of online learning experiences. The study proposes potential indicators of success, paving the way for future research in the field of online education. By identifying and refining these indicators, educators and researchers can better assess the impact of online learning platforms and communities on student outcomes, engagement, and knowledge-sharing.
