In The Mismanagement of Customer Loyalty, Reinartz and Kumar take a surgical look at the false assumptions that underlie many Customer Loyalty programs. And whilst the research they quote is somewhat dated now (2002), their findings have an uneasy and contemporary feeling of truth about them.
The popular mythology is of course that the best customers are the loyal ones: low cost to serve, willing to pay more, and to act as strong word-of-mouth.

The claim by our researchers: “Much of the common wisdom about customer retention is bunk. To get strong returns on relationship programs, companies need a clearer understanding of the link between loyalty and profits”.
Their research findings covered a high-tech corporate service provider, a large US mail-order company, a French retail food business and a German direct brokerage house. The data collected enabled them to compare the behaviour, revenue and profitability of more than 16,000 individual and corporate customers over a four year period.
They discovered “little or no evidence to suggest that customers who purchase steadily from a company over time are necessarily cheaper to serve, less price sensitive, or particularly effective at bringing in new business”.
However, they also claim that the reason that the apparent link between loyalty and profits is weak has a lot to do with the crudeness of the methods most companies use to decide whether or not to maintain their customer relationships.
RFM (Recency, Frequency, Monetary value) analysis is a popular way to sort customers. In practice, this method tends to overweight in favour of recency (eg. doesn’t distinguish different pacing patterns between frequently and infrequently purchased goods) and the monetary value component is almost always based on revenue rather than profitability. In short, it can be a very blunt instrument.
And as valuable as segmentation is, there is no substitute for identifying customers at any individual level. Knowing that 50% of your customers are loyal doesn’t exactly inform: right offer, right customer, right time, right channel.
The really interesting findings from the research came from probing further into the attitudes of loyalty – sifting out the self-declared true believers. At the grocery retailer, for example, customers who scored high on both actual and attitudinal measures of loyalty generated 120% more profit than those whose loyalty was observed through transactions alone. And in the B2B environment of the high tech corporate services provider, loyal customers of both “thought and deed” were 50% more profitable than those designated loyal by transactions alone.
This certainly mirrors our experience with CRM programs and branded online communities. It is one thing to know about transactions – “who, what, how and when” are all critical to providing context in understanding customers. However, going the last mile to understand “why” is absolutely critical. And can turn a blunt instrument into something of surgical precision.
