Downturns naturally reshape customers' needs. While competitors mindlessly cut costs, you should divide your customer base into new segments, whose emerging needs you can serve - and invest in - profitably. You'll increase market share and market capitalization.

If you run a big company, you might think it's nearly impossible to grow profits organically. Think again, say MacMillan, of the University of Pennsylvania's Wharton School, and Selden, of Columbia Business School. Locked inside your firm's customer records is a wealth of information about what your customers need and how to make more of them profitable to you. Tapped strategically, this information can generate enormous value for your company and give you a big leg up on potential invaders. The authors call it the incumbent's advantage. Using the hypothetical example of Mix C-Ment, based on the real experience of concrete manufacturer CEMEX, the authors walk through a step-by-step tutorial on strategic customer segmentation. They demonstrate how investing in and applying research about particular customers' needs for tailored products, marketing support, and technical services can greatly increase profits. But that requires seeing these offerings not as mere allocated costs but as deliberately invested resources. To exploit your incumbent's advantage, build a modest customer-characteristics database and rank your customers according to profitability. Then analyze in detail the needs and behavior of the most and least profitable 20% - and strategically use what you find. This customer-centric approach to your information should have as its counterpart a corporate structure in which cross-functional teams assigned to specific customer segments make smart resource investments using your evolving knowledge about each segment's needs and performance. Getting your customer information and your organization to work together in this way is the key to preserving your firm's dominance while increasing profits at every step of the process.

No matter how hard companies try, their approaches to innovation often don't grow the top line in the sustained, profitable way investors expect. For many companies, there's a huge difference between what's in their business plans and the market's expectations for growth (as reflected in firms' share prices, market capitalizations, and P/E ratios). This growth gap springs from the fact that companies are pouring money into their insular R&D labs instead of working to understand what the customer wants and using that understanding to drive innovation. As a result, even companies that spend the most on R&D remain starved for both customer innovation and market-capitalization growth. In this article, the authors spell out a systematic approach to innovation that continuously fuels sustained, profitable growth. They call this approach customer-centric innovation, or CCI. At the heart of CCI is a rigorous customer R&D process that helps companies to continually improve their understanding of who their customers are and what they need. By so doing, they consistently create or improve their customer value proposition. Customer R&D also focuses on better ways of communicating value propositions and delivering the complete experience to real customers. Because so much of the learning about customers and so much of the experimentation with different segmentations, value propositions, and delivery mechanisms involve the people who regularly deal with customers, it is essential for frontline employees to be at the center of the CCI process. Simply put, customer R&D propels the innovation effort away from headquarters and the traditional R&D lab out to those closest to the customer. Using the example of the luggage manufacturer Tumi, the authors provide a step-by-step approach for achieving true customer-centric innovation.

Three out of four acquisitions fail; they destroy wealth for the buyer's shareholders, who end up worse off than they would have been had the deal not been done. But it doesn't have to be that way, argue the authors. In evaluating acquisitions, companies must look beyond the lure of profits the income statement promises and examine the balance sheet, where the company keeps track of capital. It's ignoring the balance sheet that causes so many acquisitions to destroy shareholders' wealth. Unfortunately, most executives focus only on sales and profits going up, never realizing that they've put in motion a plan to destroy their company's true profitability--its return on invested capital. M&A, like other aspects of running a company, works best when seen as a way to create shareholder value through customers. Most deals are about customers and should start with an analysis of customer profitability. Some customers are profitable; others are money losers. The better an acquirer understands the profitability of its own customers, the better positioned it will be to perform such analyses on other companies. In this article, the authors show that customer profitability varies far more dramatically than most managers suspect. They also describe how to measure the profitability of customers. By understanding the economics of customer profitability, companies can avoid making deals that hurt their shareholders, identify surprising deals that create wealth, and salvage deals that would otherwise be losers.
