This dissertation investigated the relationship between knowledge conversion processes using the Technology Acceptance Model (TAM) in Thai governmental organisations. There are few studies concerned with the development of sharing and the conversion of knowledge, and none of the Thai public sector. Most Thai research studies are concerned with the development of knowledge management practices and how to use created knowledge in organisations. This study used the relationship between technology support and managing the conversion of knowledge to increase knowledge sharing in organisations. It also contributes to knowledge of technology usage and the conversion of existing knowledge process by applying the Technology Acceptance Model (TAM) to explain uptake and use of this technology. The main benefit of this research is that it is the first study available to the Thai Government on the issue of developing knowledge conversion processes by applying the Technology Acceptance Model. A better knowledge conversion procedure can improve the efficiency of Thai government departments.
