Where Internal Analysis Starts: SWOT
The Audit Every Firm Runs — and Why It Isn't Enough on Its Own
First-Principles Question: If your rival's SWOT lists the same "Strength," was it ever really a strength?
Almost every strategy deck opens with a SWOT grid. And almost every SWOT grid puts "strong brand," "talented people," or "proprietary technology" in the Strengths box — regardless of the company. That should worry you. A list that any firm in any industry could write about itself is not analysis; it is a wish list. SWOT tells you where to look (inside the firm for S/W, outside for O/T, echoing the industry vs. firm boundary from the previous session). It does not tell you whether an item you wrote down can actually survive contact with competitors. That second, harder test is what the rest of this session builds — via Collis & Montgomery's (1995) five tests and the VRIO framework.
Strengths
Internal- AWS: over $90B revenue and $24B+ operating income in 2023 — a self-funding cash engine most rivals lack.
- 200M+ Prime members worldwide by 2023, each spending roughly 4x a non-member.
- Ad network revenue of $47B in 2023 (+24% YoY) built on first-party shopping-intent data no pure ad platform has.

Weaknesses
Internal- Grocery: after the $13.4B Whole Foods deal (2017), Amazon still holds roughly 0.2–1.2% of the ~$800B U.S. grocery market vs. Walmart's ~14.5%.
- Devices: the Alexa/Echo unit reportedly ran an operating loss of $5B+ a year as of 2022.
- Pattern of costly misfires outside the core (Fire Phone write-down of $170M in 2014; Amazon Salon, discontinued).
Source: Gupta & Rodriguez, "Amazon in 2024," HBS 9-514-025.
Opportunities
External- The GenAI stack: Bedrock (managed models), custom Trainium/Inferentia silicon, and the Rufus shopping assistant — all announced/scaling in 2023–24.
- Amazon Business reached $35B in annualized sales across 6M+ business customers by 2023, inside a ~$7.2T U.S. wholesale/distribution market.
- Healthcare: One Medical ($3.9B, 2023) plus PillPack and Amazon Pharmacy extend the Prime relationship into a new spend category.
Source: Gupta & Rodriguez, "Amazon in 2024," HBS 9-514-025.
Threats
External- Cloud infrastructure itself has a supplier squeeze upstream: AWS depends on Nvidia GPUs, which depend on a single fab (TSMC) — a value-chain fragility, not just a rival.
- Content-cost inflation: Amazon spent $19B+ on TV/music content and licensing in 2023 to stay competitive with Netflix.
- Regulatory exposure to antitrust scrutiny of scale and self-preferencing across marketplace, cloud, and advertising simultaneously.
Source: Gupta & Rodriguez, "Amazon in 2024," HBS 9-514-025.
Notice the trap: "AWS" appears as a Strength. But AWS is really a bundle of resources and capabilities — custom chips, hyperscale data centers, a decade of operational learning — wrapped in one label. SWOT stops at the label. The rest of this session asks: which parts of that bundle are actually Valuable, Rare, Inimitable, and Organized enough to keep paying off, and which parts could a rival like Microsoft Azure or Google Cloud replicate with enough capital? That is the move from SWOT (a list) to RBV (a test).
The Roots of Advantage

Competitive
Advantage
Superior Performance
Each distinct activity enables firms to add incremental value by transforming inputs into goods and services. In the interplay between resources and capabilities, resources reinforce core competencies, while capabilities allow managers to orchestrate them. Strategic choices find their expression in a specific set of the firm’s activities, which leverage core competencies for competitive advantage.
The arrows leading back from competitive advantage to resources and capabilities indicate that superior performance in the marketplace generates profits that to some extent need to be reinvested into the firm (retained earnings) to further hone and upgrade the firm’s resources and capabilities in its pursuit of achieving and maintaining a strategic fit within a dynamic environment.
Case in Point: The Retail Wars
The Past: Best Buy outperformed Circuit City (bankrupt 2009) via superior employee development and customer-centric store configurations.
The Shift: More recently, Best Buy struggled because it failed to hone its competencies against Amazon.
The Lesson: Amazon leveraged a lower cost structure (no physical overhead) to undercut prices. When a firm does not continually upgrade, competitors develop equivalent or superior skills.
Companies need to look beyond visible manifestations (products) to the invisible roots of advantage. In the next section, we clarify these opaque aspects by distinguishing between tangible and intangible resources.
The Resource-Based View
Heterogeneity & Immobility
1. Resource Heterogeneity
The assumption that bundles of resources, capabilities, and competencies differ across firms. Firms in the same industry are not the same.
2. Resource Immobility
The assumption that resources are "sticky" and do not move easily from firm to firm. This allows performance differences to persist over time.
Asset Composition Shifts
Collis & Montgomery (1995): "Competing on Resources"
Writing in Harvard Business Review, David Collis and Cynthia Montgomery argue that heterogeneity and immobility are necessary but not sufficient. Before you call something a "resource" worth building strategy around, they say, test it against five questions — and note that the fourth question (appropriability) is the one most SWOT-style Strengths lists skip entirely.
Is it hard to copy? Physically unique, path-dependent, causally ambiguous, or economically deterrent to replicate?
How fast does it depreciate? Brands can outlast patents; a hot algorithm can decay in a single product cycle.
Can a different resource deliver the same customer benefit? (Superior scale beaten by superior algorithms.)
Who captures the value? Star employees, powerful customers, or channel partners can bargain away a firm's returns even from a genuinely rare resource.
Is it better relative to rivals at the specific thing that wins in this industry — not just "good" in the abstract?
The VRIO Framework
A Decision Tree, Not a Checklist — Build Your Own
Why order matters: a "yes" on Inimitability means nothing if the answer to Valuable was already "no."
VRIO is a sequential test, not four independent scores to average. Jay Barney's logic runs: if a resource is not Valuable, stop — it is a competitive disadvantage regardless of how rare it is. If it is valuable but not Rare, every competitor has it too — competitive parity. If it is valuable and rare but not costly to Imitate, you get a head start, not a moat — temporary advantage. Only when the resource clears V, R, and I does the question shift from "is the resource good?" to "is the firm Organized to capture the value?" — the same appropriability problem Collis & Montgomery raise above.
Live VRIO Assessor
Does it exploit an opportunity or neutralize a threat?
Do few (if any) competitors also possess it?
Path dependence, causal ambiguity, or social complexity block copying?
Systems, incentives, and structure aligned to exploit it?
Answer Valuable, Rare, and Costly to Imitate to see the strategic implication compute live.
Case Study: Five Guys
Applying RBV and VRIO to a Real-World Anomaly
Fundamental Question: Can Internal Resources Substitute for External Marketing?
The Context: Fast food is a marketing-heavy industry. McDonald's spends $1.6B/year on ads.
The Anomaly: Five Guys spends virtually zero.
The Session 05 Lesson: They leverage Intangible Resources (Reputation, Culture) to replace Tangible Ad Spend.
The "No Marketing" Strategy
Five Guys allocates capital differently. Instead of buying commercials, they invest in:
- Tangible Resources: Fresh meat (no freezers), peanut oil, potatoes from >42nd parallel.
- Intangible Capabilities: Fanatical service culture driven by "Mystery Shopper" bonuses.

Strategic Activity System Map
The Value Chain
Transforming Inputs into Superior Performance
Porter (1987), writing in "From Competitive Advantage to Corporate Strategy" (HBR), introduced the value chain as the unit of analysis for competitive advantage: "Every business unit is a collection of discrete activities… I call them value activities… It is at this level, not in the company as a whole, that the unit achieves competitive advantage." He groups them into nine categories — five primary activities that touch the product directly, and four support activities that make the primary ones possible. The diagnostic question for this session: which of these nine boxes is where your VRIO-tested resource actually gets deployed?
Logistics
Logistics
& Sales
*Primary Activities (Bottom) touch the product directly. Support Activities (Top) enable the chain.
Nvidia Doesn't Own Its Own Value Chain — and That's the Point (and the Risk)
Nvidia designs GPUs but outsources fabrication entirely to TSMC — a single supplier that makes over 90% of the world's leading-edge logic chips and can charge up to roughly $20,000 per advanced 3nm wafer. That is a textbook single-source procurement risk sitting inside a Fortune-favorite growth story (Yoffie & von Bargen, HBS 9-725-360).
Nvidia's own value-adding activity is chip design plus the CUDA software layer (150+ SDKs, 15+ years of investment) — the VRIO-tested resource from the calculator above. This is where nearly all of its ~73% FY2024 gross margin is earned.
Nvidia sells chips to OEMs (Dell, HP) and cloud "hyperscalers" (Microsoft, Amazon, Google) — but its own DGX systems and DGX Cloud rental service now compete directly with those same customers, a forward-integration move that Porter's "better-off test" would force you to interrogate: does Nvidia's parent-level advantage actually help the new DGX unit, or does it just borrow trouble with the channel that built the business?
This is precisely the "sharing activities vs. transferring skills vs. staying a component supplier" tension Porter (1987) describes in diversified firms — except Nvidia is running it live, in real time, up and down one value chain. Jensen Huang's own hedge: "In the event that we have to shift from one fab to another, we have the ability to do it. We won't be able to get the same level of performance or cost, but we will be able to provide supply."

Advanced Activity: The "Unfair" Advantage Simulation
Group Challenge: Diagnose the Strategic Flaw & Prescribe the Fix
The Boardroom Challenge
You are the newly appointed Chief Strategy Officer. The CEO has presented three "Unbeatable Assets." Your job: Apply the rigorous logic of VRIO to expose the hidden weaknesses and propose a strategic "fix" to turn a temporary edge into a sustainable dynasty.
The "Black Box" Algo
Resource: A predictive AI for stock trading.
Context: Returns are 20% above market (Valuable). It is proprietary (Rare). However, the lead engineer just quit to join a rival, carrying the logic in their head (Low Causal Ambiguity).
The resource is V and R, but not Costly to Imitate due to labor mobility.
Embed the algo into a complex, firm-specific software ecosystem (Social Complexity) so the code is useless without the platform.
The Exclusive Bean
Resource: 10-year exclusive contract for a rare coffee bean.
Context: Competitors cannot access it (High Cost to Imitate). However, your baristas are paid minimum wage, turnover is 150%, and customer service scores are abysmal.
The firm is not Organized to Capture Value. The potential is wasted.
Invest in training and culture (like Five Guys). Transform "buying beans" into a "premium service capability."
The Heritage Brand
Resource: A 150-year-old luxury fashion brand.
Context: History cannot be bought (Path Dependence). Customers trust the quality implicitly (Social Complexity). Management is leveraging this to launch a digital metaverse line.
V=Yes, R=Yes, I=Yes (History), O=Yes. This is a Sustainable Competitive Advantage.
Maintain brand dilution discipline. Ensure the digital expansion doesn't contradict the heritage narrative.
Group Challenge: The Strategic Turnaround
Diagnose, Engineer, and Pitch a Sustainable Advantage
Objective
Work in groups of 5–6 to diagnose a failing firm using the VRIO Framework and engineer a "Sustainable Competitive Advantage" that rivals cannot easily copy.
Assemble Your Board (5 Mins)
The Diagnosis (15 Mins)
Pick ONE scenario. Draw a VRIO table. Mark the "X" where the chain breaks.
Scenario A: The Generic App
Viral photo app with millions of users (Valuable/Rare), but competitors are cloning filters in days.
Scenario B: The Luxury Ghost
200-year-old watch brand (Path Dependent). High quality, but untrained retail staff and broken website.
Scenario C: The Leaky Lab
Revolutionary AI healthcare tech. Lead scientists are being headhunted by Google/Meta (Imitation Risk).
The "Unfair" Fix (20 Mins)
Propose a Strategic Pivot to turn "No" into "Yes".
- Complexity: Link asset to firm-specific processes so one person leaving doesn't destroy value.
- Path Dependence: Lean into history to create "lock-in".
- Org Alignment: Change incentives/software to ensure value isn't wasted (avoid Xerox PARC fate).
The Pitch (3 Mins)
Present to the class. You must answer:
VRIO Strategic Audit Scorecard
Grade Peers| Pillar | The Test | Score (1-5) |
|---|---|---|
| Valuable? | Does the "Fix" neutralize threats/exploit opps? | |
| Rare? | Is the solution unique? | |
| Inimitable? | Used Path Dependence / Causal Ambiguity? | |
| Organized? | Systems/Culture aligned to capture value? |
Devil’s Advocate Pro-Tips
Ask these "Shark Tank" questions during Q&A:
"If I hire your top 3 managers tomorrow, do I take your strategy with me?"
"Can AI provide this same result for half the price?"
"Do your current middle managers actually have the skills to run this?"

FIVE GUYSWhile competitors can see the "better burger" model, Five Guys has a 20-year lead (Path Dependence). Franchisees locked down prime locations early.
Result: First-mover advantage + Perfected competency blocks direct copying.
Substitution
AMAZONBezos didn't build better bookstores; he replaced them. Online retail offered strategic equivalence (same product) with a superior delivery method.
Result: Lower cost structure negates physical retail advantage.
Combination

Result: Mitigated Apple's competitive advantage.
Organization (O)
XEROX PARCXerox invented the Mouse & GUI (Valuable/Rare). But management was focused on copiers. They lacked the structure to capture value.
Result: Apple & Microsoft captured the value instead.
Substitution Shock (2026 Watch)
NVIDIAIn January 2025, Chinese lab DeepSeek claimed to have trained a competitive large language model at a small fraction of the compute cost analysts assumed CUDA-locked scale required — and Nvidia's market value reportedly dropped by roughly half a trillion dollars in a single trading day, one of the largest one-day losses ever recorded for a public company.
Result: A live test of Collis & Montgomery's substitutability question — can a cheaper algorithm substitute for expensive compute? Nvidia's stock recovered and the company reportedly went on to become the first to reach a $5 trillion market valuation by late 2025, but the episode is the cleanest classroom proof that even a VRIO "Yes/Yes/Yes/Yes" resource is a bet on an assumption, not a guarantee.
