Organizations are becoming more knowledge intensive. Many firms in the global market are aware of this, and they try to explore the field of knowledge management (KM) in order to improve and sustain their competitiveness. Knowledge has always been the central in the functioning of society. However, in today's "knowledge economy", organizations are increasingly aware of the need for a "knowledge focus" in their organizational strategies as they respond to changes in the environment. The aim of this paper is to describe the theoretical concepts and approaches of KM process that could be implemented in organizations by reviewing KM process theories and present suggestions for what a general process should include based on analysis of various models presented in KM. The main emphasis is laid upon the concept of goal definition review, validation, and knowledge training processes in order to make sure that KM process initiative will deliver competitive advantage to the organization.展开更多

Different categories of knowledge provide different benefits and how to integrate various categories of KM into a hybrid approach as an effective KM manner remains strategically important, and yet is still understudied. Therefore, in this paper a hybrid model that integrates principal KM applications for new service development (NSD) and the measurement of the resulting f'mancial benefits have been developed. The proposed KM model incorporates newsgroups, knowledge forums, knowledge asset management and knowledge application processes as a hybrid means for sharing organizational knowledge along two axes, explicit vs. implicit and individual vs. collective. One of the largest management consulting companies in Taiwan, China, whose process model of NSD was standing alone with KM applications, was selected for the case study. A set of hybrid KM processes was developed to implement the proposed KM model, and it illustrates an application with greater financial benefits for integrating hybrid KM practices into the business process. Based on knowledge value added (KVA) validation, the proposed KM model provides a new operating system for sharing NSD knowledge within an organization. Through the case study by measuring the achieved financial results, the proposed KM model is found to provide an exclusive hybrid platform with an empirical process model to address innovative approaches and practical values of KM within an organization.展开更多
