Time for a Data Diet? Deciding What Customer Information to Keep — and What to Toss

Heartland Payment Systems, a credit card processor, may have had up to 100 million records exposed to malicious hackers. Payment processors CheckFree and RBS Worldpay, and employment site Monster.com have all reported data breaches in recent months, as have universities and government agencies. Experts at Wharton say that personal data is increasingly a liability for companies, and suggest that part of the solution may be minimizing the customer information these companies keep.

Indeed, according to Wharton marketing professors Eric Bradlow and Peter Fader companies should deploy a technique called “data minimization.” The concept: Keep the customer data a company needs for competitive advantage and purge the rest. “I think there is a fear and paranoia among companies that … if they don’t keep every little piece of information on a customer, they [can't function],” says Bradlow. “Companies continue to squirrel away data for a rainy day. We’re not saying throw data away meaninglessly, but use what you need for forecasting and get rid of the rest.”

The problem with the data hoarding approach is that companies can’t use most of the information they keep, adds Fader. Meanwhile, they become data pack rats, chasing an illusory dream of one-to-one marketing, which he says “is a myth.
