One of the key factors that distinguishes the intelligent business enterprise of the 21st century is the emphasis on knowledge and information. Unlike businesses of the past, the fast, high-tech, and global emphasis of businesses today requires the ability to capture, manage, and utilize knowledge and information in order to improve efficiency, better serve customers, manage the competition, and keep pace with never-ending changes. Knowledge management is an important means by which organizations can better manage information and, more importantly, knowledge. Unlike other techniques, knowledge management is not always easy to define because it encompasses a range of concepts, management tasks, technologies, and practices, all of which come under the umbrella of the management of knowledge. This chapter takes a broad view of the topic of knowledge management and aims to provide a comprehensive overview of knowledge management — the technologies, processes, and concepts involved, and the challenges and future of this important area.
