Ronald Freeze is a visiting Assistant Professor of Information Systems at the W.P. Carey School of Business, Arizona State University. He received his Ph.D. in Information Systems at Arizona State University. His broad research area is knowledge management. His research has been published in the Journal of Knowledge Management as well as AMCIS, ICIS, and HICSS conference proceedings.Abstract: We examine a knowledge management (KM) success model that incorporates the quality of available knowledge and KM systems built to share and reuse knowledge such as determinants of users' perception of usefulness and user satisfaction with an organization's KM practices. Perceived usefulness and user satisfaction, in turn, affect knowledge use, which in our model is a measure of how well knowledge sharing and reuse activities are internalized by an organization. Our model includes organizational support structure as a contributing factor to the success of KM Journal of Management Information Systems/ Winter 2006-7, Vol. 23, No. 3, pp. 309-347. © 2007 M.E.

Data collected from 150 knowledge workers from a variety of organizations confirmed 10 of 13 hypothesized relationships. Notably, the organizational support factors of leadership commitment, supervisor and coworker support, as well as incentives, directly or indirectly supported shared knowledge quality and knowledge use. In line with the proposed model, the study lends support to the argument that, in addition to KM systems quality, firms must pay careful attention to championing and goal setting as well as designing adequate reward systems for the ultimate success of these efforts. This is one of the first studies that encompasses both the supply (knowledge contribution) and demand (knowledge reuse) sides of KM in the same model. It provides more than anecdotal evidence of factors that determine successful KM system implementations. Unlike earlier studies that only deal with knowledge-sharing incentives or quality of shared knowledge, we present and empirically validate an integrated model that includes knowledge sharing and knowledge quality and their links to the desired outcome -namely, knowledge reuse.Key words and phrases: information systems success, knowledge management, knowledge management success, knowledge management systems, knowledge quality, knowledge reuse, knowledge sharing, system quality, user satisfaction.Knowledge management (KM) is evolving into a strategically important area for most organizations. Broadly, KM can be viewed as the process by which organizations leverage and extract ...
