Components of customer relationship management

Customer relationship management is a combination of several components. Before the process can begin, the firm must first possess customer information. Companies can learn about their customers through internal customer data or they can purchase data from outside sources. There are several sources of internal data:
_ summary tables that describe customers (e.g., billing records)
_ customer surveys of a subset of customers who answer detailed questions
_ behavioral data contained in transactions systems (web logs, credit card records,
etc).
An enterprise data warehouse is a critical component of a successful CRM strategy. Most firms have massive databases that contain marketing, HR, and financial information. However, the data required for CRM can be limited to a marketing data mart with limited feeds from other corporate systems.

CRM system must analyze the data using statistical tools, OLAP, and data mining. Whether the firm uses traditional statistical techniques or one of the data mining software tools, marketing professionals need to understand the customer data and business imperatives.
The term “customer lifecycle” refers to the stages in the relationship between a customer and a business. It is important to understand customer lifecycle because it relates directly to customer revenue and customer profitability. Marketers say there are three ways to increase a customer’s value: (1) increase their use (or purchases) of products they already have; (2) sell them more or higher-margin products; and (3) keep the customers for a longer period of time.


The customer lifecycle provides a good framework for applying data mining to CRM. On the “input” side of data mining, the customer lifecycle tells what information is available. On the “output” side, the customer lifecycle tells what is likely to be interesting
