MGTS7301 Chap.4 Reading Industry Structure
Reading Industry Structure
Five Forces examines the structural pressures that shape industry profitability: entrants, suppliers, buyers, substitutes and rivalry. The analysis begins by defining the customer need, offer and geography because scope determines who belongs in each force.
This chapter emphasises mechanisms such as concentration, switching cost, scale and exit barriers, then converts diagnosis into positioning, exploiting change or reshaping a force while considering wider consequences.

Worked example · free
Scope a refill-store industry
- 1State that refill shops is too narrow because it excludes alternative solutions.
- 1Define the need as low-waste grocery purchasing within the city.
- 1Treat other refill stores and supermarket refill sections as direct rivals where appropriate.
- 1Treat delivery subscriptions and ordinary packaged goods as substitutes where they solve the need differently.
- 1Explain that broader scope changes the judgement of pressure and differentiation.
Key terms
- Entry barrier
- A structural requirement such as scale, capital, access, regulation or expected retaliation that makes new entry harder.
- Supplier power
- Suppliers' ability to capture value through concentration, switching costs, scarce inputs or credible forward integration.
- Substitute
- A different product or service that solves the same customer need and limits price or demand.
Reading Industry Structure FAQ
Can I add the number of favourable forces?
No. Forces differ in magnitude and interaction. One dominant pressure can matter more than several weak favourable conditions. Judge where value is captured and whether capabilities can respond.
What is the difference between a rival and a substitute?
A rival offers within the defined industry, while a substitute solves the underlying need through another route. Clear scope makes the distinction defensible. State the customer need before assigning either label.
Does an unattractive industry always mean exit?
No. A firm may position where pressures are weaker, exploit a structural change or reshape a force if it has the required capability. Wider stakeholder consequences still belong in the recommendation.
How do short-run shocks fit Five Forces?
The framework focuses on medium- to long-term structure, so a weather event, business cycle shift or temporary disruption should not automatically be treated as a force. Ask whether the event changes an underlying driver or only current performance.
Can a firm reshape industry structure responsibly?
Yes, but the recommendation should test who bears the cost. Diversifying suppliers, increasing differentiation or reducing switching friction can alter pressure without exploiting vulnerable partners. Profitability, resilience, legitimacy and stakeholder consequences should be considered together.
What evidence supports a force rating?
Name the structural driver and show its effect on bargaining or profit capture. Supplier concentration, switching cost, scale economies or substitute price-performance provide mechanisms; a bare high or low rating offers no reasoning for the board to test.
Assessment move
Practise defining one industry at three widths and note which actors move between rivalry and substitutes. State the customer need, offer and geography before touching the five-force labels. Use a boundary that is broad enough to expose alternative solutions but narrow enough to preserve a meaningful economic structure. Build a driver bank for each force.
Entry depends on scale, capital, distribution access, regulation and retaliation. Supplier and buyer power depend on concentration, switching costs and credible integration. Substitution depends on price-performance and willingness to change. Rivalry depends on growth, differentiation, fixed cost and exit barriers. Turn each driver into a because sentence rather than writing high or low on its own.
Next, rank the forces by how much value they can capture, and explain why a simple favourable count is misleading. Create two cases with the same number of attractive forces but different dominant pressures. Ask whether organisational capability changes the strategic interpretation even when the structure is difficult.
Practise three response types separately: position where forces are weaker, exploit a change and reshape a force. Then add the ethical check used in this course. A move that transfers excessive risk to suppliers or limits customer choice may improve bargaining power while weakening legitimacy, resilience or stakeholder trust. In a boardroom answer, name both the advantage and the broader consequence.
Review the tool's limits by separating medium-term structure from short-run shocks and by noting that profitability is not the whole purpose of an organisation. Finish a timed analysis with the dominant mechanism, the capability needed to respond and a review signal.
This sequence keeps the recommendation grounded in industry economics while showing that management remains responsible for the consequences of how it changes those economics.
