In plain English
Why does this company win and not the one next door? Usually because of something it has or does that others cannot easily copy.
The advanced view
The resource-based view holds that sustained advantage comes from resources that are valuable, rare, inimitable and organisationally exploited (VRIO). Capabilities are routines rather than assets, which is why they are hard to buy; the value chain locates where in the flow of activities the advantage physically lives.
The Resource-Based View argues that sustained advantage comes from resources and capabilities that are valuable, rare, inimitable and non-substitutable (VRIN, later VRIO where O = organised to capture value). The implication: strategy should be built on what the firm uniquely does well, not on which market looks attractive.
Value chain analysis (Porter, 1985) decomposes a firm into primary activities — inbound logistics, operations, outbound logistics, marketing and sales, service — and support activities. The question is where in the chain the firm creates more value than rivals, and where activities should be outsourced. Dynamic capabilities extend RBV: the ability to sense, seize and reconfigure matters more than any static resource when the environment moves.
Frameworks
VRIO
Test each resource: valuable, rare, inimitable, organised to exploit. Only all four give sustained advantage.
Value chain
Break the firm into activities and locate where relative value is created or destroyed.
Core competences
Hamel and Prahalad: bundles of skills that give access to multiple markets and are hard to imitate.
Dynamic capabilities
Sense, seize, reconfigure. Advantage in fast-moving industries comes from adaptation, not position.
Why it works
VRIO works because each test removes a way advantage can leak. Not valuable → no advantage. Valuable but common → parity. Rare but imitable → temporary advantage only. All three but not organised → value is created and not captured. It is a filter, and the useful answers are usually the ones that fail at the last step.
Common pitfalls
- ×Calling scale or brand a capability without saying what it lets the firm do that rivals cannot.
- ×Confusing a strength with an advantage — advantage is relative to a specific competitor.
- ×Assuming an advantage in one segment travels to another.

Deeper
Deeper: VRIO, and the financial signature of an advantage
A resource creates sustained advantage only if it is Valuable, Rare, costly to Imitate and the Organisation can exploit it. Most claimed advantages fail the imitation test: a better product is copied, a lower cost from scale is not.
In the numbers, a durable advantage shows up as ROIC persistently above WACC — not one good year, but a decade. Competition drives returns to the cost of capital; when it does not, ask what is stopping it: switching costs, network effects, scale economies, regulatory position, or a cost curve rivals cannot reach.
Must know cold
- ✓Advantage = higher willingness to pay, lower cost, or both.
- ✓The financial signature is ROIC − WACC sustained over a cycle.
- ✓Value chain analysis locates where the advantage is actually created.
- ✓Core competence must be transferable across products to be worth the name.
Exercises
Try each one on paper before revealing the worked solution.
Exercise 1
A company earns ROIC of 22% against a WACC of 8% for ten years. Give three hypotheses for what protects it and one test for each.
Exercise 2
Which of these passes VRIO: (a) a patent expiring in two years, (b) a 30-year distributor network, (c) a good ERP system?
