Knowledge has been viewed as a critical component for organizations. Consequently, organizations implement Knowledge Management Systems (KMSs) to seek competitive advantages but encounter mixed results. This research draws on previous information system and knowledge management system success related literature and selects eight factors that are believed to be critical for the successful implementation of a KMS. These factors were derived through a literature search of current KMS success related literature. The purpose of this study is to identify factors that could have a clear influence on the development and implementation of KMSs. The study presents the empirical examination of a theoretical model of KMS success for predicting system use by law enforcement officers. The research findings were accomplished through a validated questionnaire that surveyed 10 law enforcement officers from various agencies. These results contribute to the literature by empirically supporting the hypothesized relationships between identified success factors and KMS success. Though limited in sample size, this research can serve as a foundation for future studies, which can help identify other factors critical for KMS success.
