Porter's Five Forces Generator with Scored Verdict

Five Forces rater with attractiveness gauge

Rate each force from 1 (weak pressure on profits) to 5 (severe pressure), and jot the case evidence that justifies the number. The gauge and verdict update as you move the sliders, and everything autosaves in this browser.

Where Porter's Five Forces came from

Michael Porter published the framework in his 1979 Harvard Business Review article "How Competitive Forces Shape Strategy", and it has been a staple of strategic management courses ever since. The idea behind it is deliberately simple: an industry's profit potential is not set by how clever its companies are, but by the structure of competition around them. Five pressures — rivalry, entrants, suppliers, buyers and substitutes — squeeze profitability, and the balance between them explains why some industries stay lucrative while others fight over thin margins.

For a case study assignment, that origin matters in a practical way. Your marker is not asking whether the company is nice or its products are popular; the framework asks what structural pressure each force puts on profit. Keep your paragraphs anchored to that question and the analysis stays disciplined instead of drifting into company biography.

The five forces, in case-study wording

Each force has a textbook name and a plainer working question. Use the plain question when you write, and the textbook name when you label — that combination reads as understanding, not recitation.

Competitive rivalry

How intensely do existing players fight for the same customers? Look for price wars, discounting, advertising spend, new store openings and product upgrades in the case. Rivalry rises when competitors are numerous, similar in size, or when the market grows slowly and every win has to come from someone else's loss.

Threat of new entrants

How easily can outsiders start competing? Barriers keep the threat low: capital costs, licences, brand loyalty, distribution deals, switching costs. A case that mentions a franchise opening on every corner is telling you the threat is high, even if no specific new competitor is named.

Bargaining power of suppliers

Can the companies that supply inputs dictate terms? Few alternative vendors, specialised inputs and high switching costs all raise supplier power. Watch for contract renewals, single-source ingredients or labour shortages in the case — each is supplier pressure wearing different clothes.

Bargaining power of buyers

Can customers push prices down or demand more for the same money? Power grows when buyers are concentrated, switching is cheap, or the product is standardised and easily compared. Review complaints and price-match promises in the case are evidence of buyer power in action.

Threat of substitutes

Can the customer's need be met another way entirely? A cinema competes not with other cinemas but with streaming; a campus cafe competes with the dining hall. Substitutes cap what an industry can charge, so the case's mention of an alternative habit is usually the strongest substitute evidence you will get.

How to justify each rating with case evidence

A slider position without a reason is a guess, and graders mark guesses down. Treat every rating as a claim that needs one or two sentences of proof. The pattern that works: name the fact from the case, connect it to pressure on profit, then rate. Fact: two national chains and six independents sell within five minutes' walk. Pressure: lunchtime discounting is already visible. Rating: rivalry, 4 of 5.

Use the notes field under each slider for exactly this sentence, so the export assembles the full evidence trail for you. Where the case is silent, say so honestly — "the case gives no supplier details, so this rating assumes a competitive vendor market" is a defensible move in an exam and a rubric-friendly one in coursework. What markers penalise is not uncertainty; it is confidence with no traceable source.

One calibration tip: rate pressure on profit, not the size of the players. A single dominant supplier with no alternatives rates higher than three large suppliers fighting for contracts, because power is about alternatives, not headcount.

Turning the gauge into a verdict paragraph

The gauge converts your five ratings into a single industry attractiveness score out of 100: weak average pressure pushes the score toward 100, severe pressure pulls it toward 0. The band under the gauge labels the setting — attractive, moderately attractive or unattractive — and the verdict paragraph assembles itself from your highest and lowest ratings.

Drop the copied verdict into your case study as a draft, then edit it so the named forces match your evidence paragraphs. A verdict that cites specifics from the case is worth far more than a generic one, so replace any placeholder phrasing with the numbers and facts you collected.

Five Forces vs SWOT vs PESTLE

Three frameworks, three altitudes. Five Forces looks across one industry at its competitive structure. PESTLE scans the wider macro-environment. SWOT sits at company level, summarising everything the other two surface. If your brief names several, the usual order is PESTLE for context, Five Forces for industry structure, SWOT to consolidate, and then your recommendations.

Build the companion pieces with the PESTLE generator and the SWOT generator — both export text you can paste into the same working document, so the three analyses stay consistent with each other.
