72 M C K I N S EY Q UA RT E R LY - - - - - - Strategy’s Blind Spot D O YOU KNOW WHAT YOUR competitive advantage is? Are you sure? Competitive advantage is the most critical yet misunderstood facet of strategy. It’s more than a company’s strengths—it’s the reason customers choose its offerings over its peers’ or why its products can command a price pre mium. Competitive advantage comprises unique, hard-to-replicate assets and operating models that enable a company to build sustained value and superior returns over time. That foundation is shaky for many businesses today, our analysis shows. To identify shifts in competitive advantage, we looked for changes in market position using a metric we call the “shuffle rate”—an industry-level marker that measures the speed of change in the positions of market leaders and laggards. We found that the shuffle rate has accelerated for more than 60 percent of industries in the past decade, with an 11 percent increase in median rates (Exhibit 1). This pattern suggests that the defining elements of competitive advantage are in flux, the degree of differentiation between market players is narrowing (causing more frequent positional changes), or both. Competitive advantage is the most critical yet misunderstood facet of strategy. The result is an increasing erosion of competi tive advantage for some companies and a critical opportunity to capture greater market share for others. Businesses in a sector with a decelerating shuffle rate may find themselves stuck in lagging positions as the industry’s top performers deepen competitive moats around their leadership. Con versely, those in an industry with an accelerating shuffle rate could find opportunities to attract cus tomers previously locked in by their competitors. Yet despite the importance of acting on these shifts, recent research shows that most companies aren’t monitoring how their industry positions and competitive advantages may be changing (Exhibit 2). Despite this, most respondents report being con fident that they understand what drives customer and investor choice—a confidence that may be misplaced as change accelerates. The result is a troubling reality: While the majority of respondents recognize that their advantage is not durable, their organizations are not monitoring signals that would alert them to changes in the competitive landscape. The dynamics eroding incumbents’ competitive advantages in some industries illustrate why the shuffle rate is accelerating. For example, in entertain ment, streaming services have matured, in-theater viewing has suffered a potentially permanent decline, and creator-driven content on video-streaming platforms is competing with traditional media com panies. This realignment has been accompanied by significant M&A activity, including Netflix’s intended $83 billion acquisition of Warner Bros. Discovery and Paramount’s merger with Skydance. The foot wear industry has likewise seen substantial change. Challenger brands have rapidly gained market share from incumbents, and distribution has shifted from wholesale-dominated to direct-to-consumer models, requiring significant supply chain restructuring and changing the competitive advantages needed to win. While understanding the stability of the organiza tion’s competitive advantage is critical, so is having a shared view of what that advantage is. When busi ness leaders have different assumptions about their organizations’ advantage, aligning on what to invest in and in which markets is challenging. And since com petitive advantages are context specific, they can be hard to recognize and assess. An additional complica tion is that an organization’s competitive advantage is dependent on the capabilities of its competitors, and - - - - - -
