Turban, et al. (2007) believed understanding the critical success factors of KMS are important to understanding organizational success. Because these factors should not be judged subjectively, it is imperative to learn what has been reported in the literature. Therefore, this review begins with an understanding of the constructs of KM and KMS. Investigating the constructs of leadership and management will also be undertaken in order to determine their distinctive characteristics. Social power theory, as a means by which followers are influenced (Drucker, 1999; Yukl, 2012), will then be investigated. Finally, the researcher will investigate the constructs of personal and positional powers (Liu & Fang, 2006) to determine how these constructs influence a successful KMS. Doing so will provide researchers with a clearer understanding of how best to promote organizational success.
