The way in which companies interact with their
customers has changed dramatically over the past few years. A
customer’s containing business is no longer guaranteed. As a
result, companies have found that they need to understand their
customers better, and to quickly respond to their wants and needs.
In addition, the time frame in which these responses need to be
made has been shrinking. It is no longer possible to wait until the
signs of customer dissatisfaction are obvious before action must be
taken. To succeed, companies must be proactive and anticipate
what a customer desires. In this paper we are going to discuss the
Data Mining techniques used in Customer Relationship
Management.
