CRM is customer relationship management. These are applications which create more effective, efficient relationships between companies and customers. In these systems, although software plays a great role, CRM does not consist of only software.
The aim of CRM is to predict customers' needs and reach the right target audience.
For a truly successful CRM program, the company must be client-oriented as its philosophy. For a successful CRM program, you need to collect and make usage of information correctly, which is also achieved through a successful CRM program. So, not only philosophy or software is enough.
