These days, high growth and rapid changes in technology on the one hand, and the utilization of new approaches emerged in the economy and management literature on the other, make knowledge resources become more important than other organizational resources. This viewpoint is based on two main sources; one of them is IT resource and the other is human resource. This kind of attitude to these sources leads to two different approaches of knowledge management: one is related to IT resource and the other is related to human resource. In the investigations about the causes of failure in the most knowledge management projects in knowledge-based organizations, human resource and IT resource approaches are studied separately. In this paper, by these approaches, not only has been the causes of failure in knowledge management projects investigated, but also the importance of these approaches has been studied, too. The study shows that the technology and its benefits cannot be ignored. At the same time, for making organizations less formal, non- technological resource (human resource) management should be at the helm of management priorities. In order to use technology advantages while avoiding its disadvantages, organizations' knowledge resource management should pay attention to the alignment between its technology and human resources. Furthermore, studies show that network infrastructures (extranet, intranet and internet) can provide a proper environment for human resource management.
