The research characterized the sectors’ culture using taxonomy of four culture types that identified their composition and dominant culture type. In addition, it validated a model used to determine the main approach used by employees for the flow of knowledge (Roman, 2004; Ribi่re, 2001). Furthermore, the associated KMS success level was assessed through the evaluation of eight critical success factors. These areas were compared and contrasted at different hierarchic levels of the enterprise, namely the organization and the work unit. The analyses allow understanding of the effects the enterprise culture has in the implementation of a KMS. As a result, chief knowledge officers (CKOs), knowledge managers, and others can benefit by gaining greater insight into the likelihood of success when implementing a KM effort within the government and nonprofit sectors, while integrating the human aspect to leverage the enterprise intellectual assets in the most efficient and effective way. Furthermore, in the next chapter (Chapter 5), Dr. V. Ribi่re identifies critical cultural components for building a knowledge-center culture.
