What is Customer Relationship Management (CRM) ?
A business system purporting to enable organizations to better serve their customers through the introduction of reliable processes and procedures for interacting with those customers.
In today's competitive business environment, a successful CRM strategy cannot be implemented by only installing and integrating a software package designed to support CRM processes. A holistic approach to CRM is vital for an effective and efficient CRM policy. This approach includes training of employees, a modification of business processes based on customers' needs and an adoption of relevant IT-systems (including soft- and maybe hardware) and/or usage of IT-Services that enable the organization or company to follow its CRM strategy. CRM-Services can even replace the acquisition of additional hardware or CRM software-licences.
