Why Do Firms Differ?
"Why do some firms thrive while others merely survive—even in the same industry?"
"Strategy is as much about deciding to do things differently from competitors as it is about choosing not to do certain things at all."
That’s the puzzle that strategy scholars have tried to decode for decades. If all airlines fly planes, all banks lend money, and all universities teach students, why do some consistently outperform others?
We can solve this riddle through the lens of industry and firm effects. Industry structure shapes the playing field, while firm choices decide how the game is played. Industry effects (our focus in Session 4 with Porter's Five Forces) arise from forces common to all players—entry barriers, supplier power, customer dependence, and rivalry. These elements set the profit potential of an industry.
Yet firm effects stem from what leaders actually do: how they position, differentiate, innovate, and lead. Researchers have compared these effects across hundreds of firms. The results (see Exhibit 3.2, displayed here) are striking. Only about 20 percent of a firm’s performance can be traced to its industry—its external environment. A much larger share, nearly 55 percent, comes from firm effects—the specific actions, routines, and leadership choices within the company. The remaining 25 percent reflects random shocks, business cycles, or unexplained variance.
So while external conditions matter, the story of success is mostly written *inside* the firm. Strategic leaders can’t control the economy or competitors, but they can shape decisions that expand the gap between value created (V) and cost incurred (C). The larger that gap, the stronger the competitive advantage.
The takeaway for students of strategy? Understand your industry, but master your firm. The structure sets the boundaries—but leadership defines the possibilities.
Industry, Firm, and Other Effects Explaining Firm Performance
Core Competencies, Resources, & Capabilities
"We all say Nvidia has a 'moat.' But what is that 'moat' actually made of? How do we build a vocabulary to describe it?"

“Make the Best Burger. Don’t Worry about Cost.” — Jerry Murrell, Founder of Five Guys
Five Guys became the fastest-growing restaurant chain in the U.S. by focusing obsessively on a single core competency: delivering a customized, made-to-order burger and hand-cut fries using only the highest-quality ingredients.
The focus: high-quality burgers and fries.
Cultural buzz (like President Obama's visit) replaced paid marketing.
While competitors like McDonald's compete on cost, speed, and marketing, Five Guys built its entire system around quality. This philosophy came directly from founder Jerry Murrell.
This relentless focus on quality is their core competency. It's a unique strength embedded deep in the firm's culture and activities. It allows them to create higher value for customers, justifying their higher prices and longer wait times.
"Making Quality Cool"
The origin: solving a real problem for hardcore anglers.
The expansion: high-performance drinkware for a mass market.
Yeti, founded in 2006, turned a basic plastic cooler into a high-performance status symbol, achieving a $1.5B valuation. Its success stems from two core competencies: superior quality/performance and creating a "coolness factor".
This combination of competencies allowed Yeti to differentiate a commodity product, command a premium price, and build a cult-like following that expanded from its niche into the mass market.
A firm's assets. They can be tangible (physical) or intangible (non-physical).
Nvidia's global R&D labs, like this office in Yokneam, are a key *tangible resource* that supports its innovation capabilities.
Key Insight: Intangibles Dominate
While tangible assets are necessary, Nvidia's competitive advantage is overwhelmingly built on intangibles. The CUDA platform is a massive, proprietary resource that locks developers into Nvidia's ecosystem.
The VRIO Framework
"Okay, so Nvidia has resources. But which ones *actually matter*? How can we tell a truly strategic asset from just 'a thing we're good at'?"
The RBV model sees resources as key to superior performance. It rests on two critical assumptions about the nature of resources:
A firm is a unique bundle of resources and capabilities. These bundles differ across firms (e.g., Nvidia's CUDA ecosystem vs. AMD's hardware focus).
Resources tend to be "sticky" and don't move easily from firm to firm. This is why resource differences can be long-lasting.
To be the basis of a competitive advantage, a resource must be V-R-I-O:
Does it help exploit an opportunity or neutralize a threat? (Increases economic value, V-C)
Is it possessed by few (or no) other firms?
Do firms without it face a cost disadvantage in obtaining or developing it?
Does the firm have the structure and systems to exploit the resource's potential?
A VRIO analysis evaluates a firm's resources and capabilities based on four criteria: Value, Rarity, Imitability, and Organization. Resources/capabilities that satisfy all four provide a sustained competitive advantage.
| Company & Capability | VRIO Dimension | Assessment | Competitive Implication |
|---|---|---|---|
| Tesla: Supercharger Network Capability |
Value | Yes. Provides essential, reliable, and convenient charging infrastructure, alleviating "range anxiety" for customers. | Competitive Advantage (potential) |
| Rarity | Yes. Tesla's network scale and integration is unique; no other auto manufacturer has an equivalent, company-controlled network. | Temporary Competitive Advantage | |
| Imitability | Difficult/Costly. Building a network of comparable scale and seamless integration requires immense capital and time. However, competitors are starting to gain access to the network. | Temporary Competitive Advantage | |
| Organization | Yes. Tesla is fully organized (vertically integrated) to build, maintain, and leverage this network for sales and customer retention. | Sustained Competitive Advantage (for now) | |
| SpaceX: Rapidly Reusable Rocket Technology |
Value | Yes. Drastically reduces the cost of space launches, enabling more missions and new ventures like Starlink. | Competitive Advantage (potential) |
| Rarity | Yes. Currently the only company capable of routinely and reliably landing and reusing orbital-class rockets. | Temporary Competitive Advantage | |
| Imitability | Extremely difficult/Costly. Requires a unique "build-test-learn" culture, massive R&D, engineering talent, and proprietary processes. | Sustained Competitive Advantage | |
| Organization | Yes. The company culture, structure, and processes are entirely focused on rapid iteration and maximizing this reusability. | Sustained Competitive Advantage | |
| Nvidia: AI and GPU Platform (CUDA) Capability |
Value | Yes. Essential for powering AI, data centers, and advanced graphics, meeting massive market demand. | Competitive Advantage (potential) |
| Rarity | Yes. Nvidia's GPU architecture and accompanying software ecosystem (CUDA) are the industry standard and unmatched. | Temporary Competitive Advantage | |
| Imitability | Difficult/Costly. Replicating the full-stack ecosystem (hardware, software, developer base) is a multi-year, multi-billion dollar effort. | Sustained Competitive Advantage | |
| Organization | Yes. Nvidia is structured to continually innovate and leverage its platform dominance through R&D and ecosystem support. | Sustained Competitive Advantage | |
| Yeti Products: Premium Brand Image and Durability |
Value | Yes. Allows for premium pricing and strong customer loyalty in a competitive market. | Competitive Advantage (potential) |
| Rarity | Yes. Yeti has achieved an almost cult-like brand status for "ruggedness" that is rare for cooler/drinkware companies. | Temporary Competitive Advantage | |
| Imitability | Difficult/Costly. Brand reputation is built over years of consistent product performance and effective marketing; it cannot be instantly replicated. | Sustained Competitive Advantage | |
| Organization | Yes. The company successfully aligns its marketing, product development, and supply chain to reinforce its premium, durable image. | Sustained Competitive Advantage | |
| Five Guys: Consistent, High-Quality Fast Food Operations |
Value | Yes. Customers highly value the fresh ingredients, customization, and consistent experience. | Competitive Advantage (potential) |
| Rarity | No (partially). Other fast-casual chains also offer quality and customization (e.g., Shake Shack, In-N-Out). | Competitive Parity | |
| Imitability | Easy. Operational procedures can be observed, reverse-engineered, and replicated by competitors with capital. | Temporary Competitive Advantage | |
| Organization | Yes. The franchise system and training are well-organized to ensure consistency. | Temporary Competitive Advantage |

"From $16 Billion IPO to $1.8 Billion... in one year."
Groupon's "daily deal" model was a classic VRIO failure that helps explain its collapse:
Result: As the VRIO model predicts, a resource that is Valuable and Rare, but *Not* costly to imitate, leads to a Temporary Competitive Advantage, which is exactly what Groupon had before it collapsed.
Sustaining the Advantage
"Nvidia has a huge advantage *today*. But in tech, advantages are temporary. What's stopping Google or AMD from catching up and making CUDA irrelevant?"
These are barriers that protect your advantage from being copied. They make imitation (the "I" in VRIO) difficult.
Nvidia's "CUDA Moat"
An advantage is never permanent. This is a firm's ability to create, deploy, modify, and reconfigure its resources to adapt to a changing environment.
Nvidia's Pivots
Nvidia's *real* strength is its dynamic capability. It has successfully adapted its core competency (parallel processing) to new markets:
Its ability to *sense* the AI trend early and *seize* it by investing billions in CUDA is a textbook example of dynamic capabilities. A Core Rigidity is the opposite: a former core competency that turned into a liability (e.g., Kodak's focus on film).
The Value Chain
"Where in Nvidia's complex 'assembly line'—from R&D to sales—is the value *actually* created, and where are the hidden risks?"
The Value Chain describes the internal activities a firm engages in when transforming inputs into outputs. Each activity adds incremental value. It's a way to break down the firm into a series of activities to see which ones drive value and which ones drive cost.
