Customer Relationship Management:

Customer Relationship
Management (CRM) tries to use all measures to understand customers
and invest the extracted knowledge to implement marketing strategies,
control production, and coordinate the supply chain.For example, by analyzing customer
profiles, we can find the group of customers who bought a particular
product and encourage similar customers have not bought that product to
buy it. Furthermore, by studying the profiles of customers who have left
the company, a special strategy can be built to retain customers who are
expected to leave, because it is less expensive to retain an existing customer
that to win a new one.
