Knowledge management is an important emerging field of science that holds great potential for enhancing the value of organizations, industries and even whole economies. It can deliver competitive advantage such as greater competencies and synergy, more balanced decisions and less errors, more creativity and innovation, broader collaboration and knowledge sharing, and easier links to expertise and deeper understanding. Knowledge management has been used in most product-based companies and it has also extended the use in service industry. Tourism sector, which is a part of service industry, has been a key factor in the overall development of Malaysia, thus accounts for effective implementation of knowledge management. Although, existing studies have derived the critical success factors of knowledge management from various industries' viewpoints, however, to date, critical success factors for implementing knowledge management in the tourism sector have not been comprehensively determined. There are not many studies looking closely to explain the knowledge management situation in the tourism sector while this sector is continuously growing in Malaysia. Owing to this matter, this paper aims to bridge this gap by identifying the critical success factors of knowledge management in Malaysian tourism sector. [ABSTRACT FROM AUTHOR]
