U.S. businesses spend $800 billion annually on sales force compensation and another $15 billion on sales training. Yet the backward-looking metrics they rely on (such as revenue generated) to gauge the impact of this spending provide limited insight into how a salesperson will do going forward and what types of training and incentives will be most effective. As a result, many companies misallocate sales force investments. The authors worked with data from a Fortune 500 B2B software, hardware, and services firm to develop a method for measuring reps' future profitability. The metric, salesperson future value (SFV), is the net present value of future cash flows from a salesperson's existing and prospective customers minus the costs of developing, motivating, and retaining the rep. The SFV analysis revealed that the firm had been overvaluing poor performers and undervaluing stars. Using the SFV calculations and data on each rep's prior training and incentives, the authors segmented reps according to whether they were motivated more by training or by various incentives. The firm then increased training for some reps and increased incentives for others, thus achieving an 8% increase in SFV across the sales force. The firm also increased its investments in high-SFV reps and reduced investments in low-SFV reps--a reallocation of resources that increased the firm's revenue by 4%.

The customers who buy the most from you are probably not your best marketers. What's more, your best marketers may be worth far more to your company than your most enthusiastic consumers. Those are the conclusions of professors Kumar and Petersen at the University of Connecticut and professor Leone at Ohio State University, who analyzed thousands of customers in research focused on a telecommunications company and a financial services firm. In this article, the authors present a straightforward tool that can be used to calculate both customer lifetime value (CLV), the worth of your customers' purchases, and customer referral value (CRV), the value of their referrals. Knowing both enables you to segment your customers into four constituent parts: those that buy a lot but are poor marketers (which they term Affluents); those that don't buy much but are very strong salespeople for your firm (Advocates); those that do both well (Champions); and those that do neither well (Misers). In a series of one-year experiments, the authors demonstrated the effectiveness of this segmentation approach. Offering purchasing incentives to Advocates, referral incentives to Affluents, and both to Misers, they were able to move significant proportions of all three into the Champions category. Both companies reaped returns on their marketing investments greater than 12-fold--more than double the normal marketing ROI for their industries. The power of this tool is its ability to help marketers decide where to focus their efforts. Rather than waste funds encouraging big spenders to spend slightly more while overlooking the power of customer evangelists who don't buy enough to seem important, you can reap much higher rewards by nudging big spenders to make referrals and urging enthusiastic proponents of your wares to buy a bit more.

It's bad enough to lose a trusted employee who works well within your organization, but when you lose a star performer who has built up strong customer relationships, something else is at stake: The star's customers may also walk out the door. In a two-year study of more than 200 people from 57 companies, Neeli Bendapudi and Robert Leone found that most strategies to keep customers when stars leave are largely ineffective because they grow out of a company's perspective, not a customer's. The authors asked customers how they felt and discovered three main concerns. First, customers can become attached to a particular key contact employee, and if that person leaves, they wonder whether service will suffer. You can forge a broader relationship by ensuring that customers interact with many employees, using techniques like deploying teams, rotating staff, and offering one-stop shopping. Second, customers fear that a replacement won't be as good as the employee who left. You can combat this by stressing the quality of all your employees--not just superstars. Publicize your hiring practices, training, and employees' achievements. Third, customers want information about the changeover and how you will manage the transition. Communicate the identity of a replacement in advance of a departure, and have the outgoing employee introduce the new person. Addressing all areas of customer concern in concert tells customers that you value their business and that you deserve to keep it. In the article, the authors also include a scorecard to rate your company on how well you are protecting customer relationships when employee turnover occurs.
