Financial services companies in general, and banks in particular, find  themselves in unexplored competitive territory in the mid-1990s. 
Industry reform continues to blur traditional distinctions between  commercial banks, investment banks, broker dealers, and insurance   companies.   
  
Competition is fierce, and more than a few observers believe that the  battle will probably be won through technology and service delivery. 
The strategies, resources, and skills required for success in banking  are changing rapidly. In the 1980s and early 1990s, the ability to control   costs and benefit from economies of scale were paramount.   
  
Though these remain important, they have been joined by the need to  analyze more effectively and serve the customer. 
Key questions that a banking company must answer are: "Who is my  customer? How profitable is he or she? What is the lifetime value of my   customer, and how can I most effectively manage that relationship?"   
Given the huge amount of information required to analyze customer  attributes, data warehousing provides the mechanism to answer these   critical questions.   
  
Banking and other financial services institutions need to focus on three  primary areas where data warehousing can be a crucial lever for competitive   success. They are:   
*Customer acquisition and management. Here the warehouse provides a  means of viewing the bank's entire relationship with a customer across all   portfolio segments, and provides the opportunity to realize the full   potential of the relationship through every stage in a customer's life   cycle.       
*Service delivery. The warehouse is the "brain center" for delivering  services to the customer as well as bringing together all the information   needed to manage and track the quality of those banking services   effectively.     
*Profitability management. The warehouse is the system for gathering and  analyzing multidimensional views of profitability. Banking executives today   understand that it is not enough to understand profitability only from the   customer or product level. They also must look at profitability in terms of   geography, type of business, delivery channel, and even specific   transactions.         
  
Price Waterhouse has identified what it believes to be eight critical  actions for banks to take to leverage data warehousing technology in order   to increase market share and profitability in the years ahead.   
Though it is worth noting that many of the country's largest banks are  in the process of taking these actions. They are applicable to every   financial services institution interested in achieving or maintaining its   competitive positioning throughout the course of the decade.     
The eight critical actions are:
1. Using data warehousing technology to better understand customers and  their financial performance. 
2. Analyzing transaction data to increase profitability by identifying  attractive markets and customers. 
3. Using data to forecast a customer's lifetime value to your bank, and  projecting his or her behavioral characteristics over a lifetime. 
4. Aligning the internal organization of your banking company to serve  each of its customer segments through a unified process. 
5. Using data warehousing, including nonproprietary demographic  information, to develop a target marketing capability. 
6. Tracking the behavioral attributes of customers in managing their  accounts, such as the balances they maintain, when their pay-off dates are,   etc.   
7. Using data warehousing systems to manage customer segments as  distinct portfolios. 
8. Implementing more sophisticated financial analysis tools to more  effectively measure the financial impact of individual customers and   similar customers.   
You don't need to be a technologist to project that data warehousing  will be a cornerstone of successful management of bank customer   relationships.   
Institutions that truly want to focus on serving the customer will need  to build data warehouses and implement tools to allow their business units   to analyze and use information quickly and efficiently.   
And, just as important, they will need to change the way they think  about customers, systems, and profitability to take advantage of the   inherent power in the billions of pieces of data - which we already have -   that tell us so much about our customers, about how we serve them, and   about how we perform as organizations.
