Knowledge management refers to acquisition, creation, dissemination, and utilization of knowledge. Knowledge is becoming an important resource for today’s organisations, and enterprises are keen to deploy this resource to improve their products, services, and processes as well as ensure delivery on demand. Through knowledge management, businesses aim to increase efficiency, reduce costs, and most importantly, retain customers. Enterprises in the electronic commerce arena are already aware of the importance of understanding customer attitudes and their buying habits and are, therefore, taking huge strides to ensure that they employ appropriate techniques to manage the information at hand. This chapter discusses the variety of approaches that business enterprises have adopted for the acquisition of customer information and its deployment and outlines the processes relevant to knowledge management in the context of electronic commerce.
