Porter’s Five Forces — Lesson

Source: PortersFiveForces

The framework answers one question: why are some industries consistently profitable and others consistently aren’t? Not which firm wins — which industry is worth being in at all.

The Five Forces — Exact Names, No Shortcuts

ForceWhat it measuresHigh = bad for profits
Rivalry Among Existing CompetitorsHow intensely firms fight each other on price, features, market sharePrice wars → margins collapse
Threat of New EntrantsHow easy it is for outsiders to enter the marketEasy entry → incumbents can’t raise prices
Threat of SubstitutesWhether customers can switch to a different type of productSubstitutes cap pricing power
Bargaining Power of BuyersHow much leverage customers have to push prices downPowerful buyers squeeze margins
Bargaining Power of SuppliersHow much leverage input providers have to raise pricesPowerful suppliers eat your margins

The one you keep getting wrong: Force #1 is not a “threat” — it’s Rivalry. It is the central force. Write it: Rivalry Among Existing Competitors.

Substitutes — Why It’s Distinct from Rivalry

Rivalry = someone else sells the same thing (Air Canada vs. WestJet). Substitutes = someone sells a different thing that satisfies the same need (Via Rail vs. Air Canada — train vs. plane).

The substitute doesn’t have to be inferior. If enough customers switch to the substitute when prices rise, your pricing power is capped. That’s the mechanism.

Airlines example (zero-star industry):

  • Rivalry: intense — WestJet vs. Air Canada vs. Flair, constant price wars
  • Supplier power: Boeing and Airbus dominate manufacturing; labour unions are powerful → airlines have almost no negotiating leverage
  • Substitutes: trains, cars, video calls for business travel
  • Buyer power: ticket comparison sites give consumers full price transparency
  • New entrants: high barriers (capital, regulation, slots) — this is the one favourable force

Exam Trap

Industry attractiveness ≠ industry profitability. Airlines are exciting — and structurally terrible. Software can be boring — and structurally excellent (high barriers, low substitutes, weak buyers).

Technology is not a sixth force — it reshapes the existing five.

Rapid-Fire Recall Drill

Cover the right column and say each force name aloud:

  1. Intensity of fighting among incumbents → Rivalry Among Existing Competitors
  2. Ease of outsiders joining the market → Threat of New Entrants
  3. Customers switching to a different product category → Threat of Substitutes
  4. Customers demanding lower prices → Bargaining Power of Buyers
  5. Input providers raising costs → Bargaining Power of Suppliers
