Why Competitive Advantage No Longer Lives Inside the Firm

For much of the past half-century, competitive advantage was understood as something a firm could largely engineer internally. Strategy focused on capabilities, scale, differentiation, cost position, and execution discipline. The implicit assumption was that if a firm organised itself well enough, it could largely determine its own outcomes.

That assumption no longer holds.

In many industries today, firms execute competently and still struggle to sustain pricing power or strategic relevance. Margins compress despite operational improvements. Growth comes without leverage. Decisions that appear sound internally are neutralised externally. These outcomes are often misdiagnosed as execution failures, when in fact they reflect a shift in where advantage is created.

Consider a consumer business that invests heavily in brand, product quality, and customer experience, only to find itself increasingly dependent on a small number of digital platforms for distribution. Internally, the business may be stronger than ever. Externally, it has ceded pricing power, data access, and customer relationships to intermediaries it does not control. The locus of advantage has moved.

Or take a financial services institution that modernises its core systems, improves risk management, and launches new products, yet remains constrained by payment rails, regulatory structures, or clearing mechanisms it cannot influence. The firm performs well, but the ecosystem captures a disproportionate share of value.

In these situations, competitive outcomes are shaped less by what happens inside the firm and more by how the firm is positioned within a broader system of platforms, regulators, standards, partners, and dependencies. Internal excellence becomes table stakes rather than a source of differentiation.

This does not mean that strategy has become irrelevant. It means that strategy must extend beyond the firm boundary. Leaders must make explicit choices about where they sit in the ecosystem, which dependencies they accept, which they attempt to shape, and which assets they can use to anchor long-term influence.

Competitive advantage has not disappeared. It has migrated. Firms that continue to look only inward will increasingly find themselves optimising performance in a game whose rules they did not design.

The question for leaders is no longer whether they execute well, but whether they are positioned in a system that allows execution to matter. Our Ecosystem Advantage Strategy service is built around this shift. For leaders navigating these questions, we welcome a confidential conversation.
