Plenty of customers and no problems with utilizing production capacity in full mean no pressure to care for customers. The CRM importance is growing with the competition increasing its pres-sure and with difficulties in winning new customers or maintaining existing ones. To understand CRM better is nowadays a standard business management strategy in selecting and guiding the most precious customer relationship.CRM management implementation for businesses is by no means a low-cost affair. Even that more than 50% cases are unsuccessful . The failure is often caused by the wrong assumption that CRM is a software tool guiding all the customer relationship. But CRM is not such a tool. It is supporting software, not a centrepiece.Based on theoretic foundations and many years of my own research of CRM implementation in a specific corporation (Z ELEKTRO), I shall recommend the following 7 steps procedure, after the most important first one is realized.During the 90´s we witnessed something like a revolution in marketing, meeting new approach to the customer theory, using new, better and less expensive IT and new methods for solving cus-tomer relationship. Shortly, this thing called database marketing became relationship marketing, bringing new software solution and finally the CRM, a broader, across- the-board concept. Many experts warn against technology being the main force for CRM implementation. The key for custo-mer relationship is the approach toward the society and structure used for its acceptance. Inability to accept this customer-centric approach the heart of CRM system is a reason why the opinion about this system is often not a positive one.
