What are Porter's Five Forces?

Porter's Five Forces identify the key pressures on an industry that impact the ability of a business to compete with rivals. It helps managers think strategically about the environment in which the business operates.

Porter's Five Forces model identifies the main competitive pressures on a business within an industry:

1. Threat of new entry

2. Buyer power

3. Supplier power

4. Threat of substitution

5. Industry rivalry

Porter argued that once a business fully understands these pressures in their context, they can take strategic decisions to achieve and sustain a competitive advantage.

What is entry threat?

If new competitors can enter an industry quickly and without investing a lot of money, then the barriers to entry is low and the threat of new entrants is high.

· The market is likely to contain a large number of rival businesses

· Individual businesses are likely to have little power

Where the barriers to entry are too high for new businesses to gain a foothold and compete in the market, the threat of new entrants is low.

What is buyer power?

When a business sells to a small number of customers, those customers have significant power to negotiate lower prices.

· The business has few options when it comes to customers

· It will have to price and sell products according to customer demands

Where a business has a high number of customers, those customers have less power.

· It is likely to be able to charge a high price for a product that is relatively inexpensive to produce

What is supplier power?

Where a business has a lot of choices over the suppliers from which it buys components:

· It is likely to be able to shop around for lower price

Where a supplier has significant power over a business as a result of offering a specialised component or where there are a small number of suppliers in the market:

· The business has little choice over the source of its suppliers

· It is likely to have to pay high prices for its components and accept suppliers' terms and conditions

What is rivalry?

When there are many competitors selling similar products, the business will have little power.

· Many rivals are trying to get a more significant share of the market

· Customers have a lot of choices and can shop around

When a business offers products in an industry with little or no competition, it has more power, can use premium pricing and dominate the market.

What is the threat of substitutes?

Where customers can easily swap a businesses products for those of a rival, the business has little power.

· The business is likely to have to compete on price or invest heavily in developing a USP

Where substitution is unlikely, a business has significant market power.

· It is likely to be able to charge a high price for its products and may be less inclined to innovate

How do businesses use Porter's Five Forces to shape competitive strategy? (Threat of new entrants and bargaining power of buyers)

Threat of new entrants: Companies raise barriers to stop new rivals by investing in patents, large-scale production or strong brands so it's expensive for others to start up. Example: Drug companies like GlaxoSmithKline spend heavily on research and hold long patent protections. These measures can keep new competitors out of the market for years.

Bargaining power of buyers: When customers can demand lower prices, firms make their products stand out or lock customers in with loyalty programmes to keep prices stable. Example: Apple's iPhone range, including its App Store, iMessage and accessories, makes it hard and costly for users to switch to another brand.

How do businesses use Porter's Five Forces to shape competitive strategy? (Bargaining power of suppliers and threat of substitutes)

Bargaining power of suppliers: If few suppliers control important inputs, businesses use multiple suppliers, make their own parts, or sign long contracts to secure better terms. Example: Supermarkets like Tesco and Sainsburys sell own-brand foods to reduce reliance on big suppliers such as Nestlé or Unilever and negotiate lower prices.

Threat of substitutes: When other products meet the same need, firms add unique features, bundle services or improve convenience to encourage customers to remain loyal. Example: Cinema chain Vue offers luxury recliner seats, gourmet snacks and membership plans so visiting is more exciting and social than watching films at home on streaming services.

How do businesses use Porter's Five Forces to shape competitive strategy? (Competitive rivalry among firms)

Competitive rivalry among firms: In highly competitive markets, companies choose to be the lowest-cost producer or differentiate on quality and service. Example: Ryanair competes on being the cheapest airline in Europe, while British Airways focuses on premium cabins, lounges and frequent-flyer benefits.

Examiner Tip: When supplier power rises or rivalry intensifies, show how this squeezes margins, then suggest a defence (e.g., differentiation) for evaluation. Balancing threat with strategy helps you achieve better analysis marks.
