Organizations continue to struggle with encouraging employees to participate in knowledge management initiatives. Research is replete with examples of organizations that implemented knowledge management systems in order to find them under utilized. In this paper, we report the results of a case study conducted to examine the impact of system, environment, and procedures on knowledge submission frequency. Our findings indicate that in the absence of a consistently publicized procedure for knowledge management, system and environmental characteristics (i.e., supervisor relationship) are the most important factors in knowledge submission frequency. However, once the procedures are publicized clearly and repeatedly, system and procedural characteristics are most influential in predicting knowledge submission frequency.
