While research on Intranet effectiveness has been greatly reported in the literature, gaps still exist particularly in the development of a theoretical framework from a user-based perspective. This paper attempts to discuss at a conceptual level on the concept of Intranet effectiveness and further analyze the effectiveness framework with several contributing factors grouped as organizational, technological and individual. Through in-depth review of relevant literature in the information systems and the knowledge management fields the paper proposes a conceptual framework for a study to be conducted on the corporate Intranet effectiveness.
