  1. Use analytical tools in business contexts, including Porter's five forces.
  2. Explain Porter's five forces: supplier power, buyer power, competitive rivalry, threat of substitution and threat of entry.
  3. Analyse business data and information to identify relationships and interrelationships in business situations.
  4. Evaluate business strategies using business criteria to make decisions and recommendations.

Porter's five forces is used to analyse competitive pressure in an industry. It is especially useful for mature and post-mature businesses because it explains why profits, market share or customer loyalty may be under pressure. The five forces are supplier power, buyer power, competitive rivalry, threat of substitution and threat of entry.

Porter's five forces example

Supplier power

Supplier power is high when suppliers can raise prices, reduce quality, control access or impose conditions. This happens when there are few suppliers, switching suppliers is difficult, inputs are specialised, the supplier has a strong brand, or the business depends heavily on a particular input.

For example, a boutique bakery using a rare imported ingredient may face high supplier power if only one supplier can provide it. A supermarket buying standard packaging may face lower supplier power if many suppliers compete. High supplier power can reduce efficiency because input costs rise. It can also damage effectiveness if shortages prevent the business from meeting customer demand.

Buyer power

Buyer power is high when customers can pressure the business to lower prices, improve quality or offer better terms. Buyer power increases when customers have many alternatives, switching is easy, products are similar, customers are price-sensitive, or a small number of customers account for a large share of revenue.

For a mature business, buyer power often rises because competitors copy the product and customers can compare prices online. A business can reduce buyer power by differentiating, improving loyalty, creating switching costs or serving a niche that values specific benefits.

Competitive rivalry

Competitive rivalry refers to the intensity of competition among existing firms. Rivalry is high when many competitors operate in the market, growth is slow, products are similar, fixed costs are high, or businesses use aggressive price and promotional tactics. High rivalry often reduces margins and forces businesses to spend more on marketing, service or innovation.

In a hostile competitive environment, rivalry may become the dominant force. A business may need a clear USP, relationship marketing, operational efficiency or repositioning to avoid competing only on price.

Threat of substitution

Substitutes are different products or services that satisfy the same customer need. A cinema competes with streaming, restaurants compete with meal kits, gyms compete with fitness apps, and taxis compete with ride-share platforms. Substitutes are dangerous because they may come from outside the traditional industry.

A mature business should ask what need the customer is really meeting. If customers do not need the exact product, they may switch when a substitute is cheaper, easier, more sustainable or more convenient. Repositioning often involves showing why the business provides value the substitute cannot easily match.

Threat of entry

Threat of entry is high when new competitors can enter the market easily. Entry is easier when capital requirements are low, legal barriers are low, technology is accessible, brand loyalty is weak and distribution channels are open. Entry is harder when firms need large investment, licences, specialised knowledge, scale, patents, strong supplier access or trusted brands.

Digital markets can increase threat of entry because small competitors can reach customers without physical stores. However, entry is not the same as success. A new competitor may enter easily but still struggle to win trust, scale or repeat customers.

Worked industry example

A local independent pharmacy is deciding how to respond to online discount pharmacies.

| Force | Evidence | Implication | |---|---|---| | Supplier power | Medicine supply is regulated and some suppliers are essential | Limited flexibility in core product sourcing | | Buyer power | Customers can compare prices online | Price-sensitive customers may switch | | Rivalry | National chains and online stores promote discounts | Margins are under pressure | | Substitution | Telehealth and delivery services reduce need to visit | Convenience is a major threat | | Entry | Regulation limits some entrants, but online models scale quickly | Trust and service remain important barriers |

This analysis suggests the pharmacy should not try to win only on price. A stronger strategy may reposition around professional advice, vaccinations, medication management, urgent local access and trusted relationships. That may improve stakeholder satisfaction and competitiveness even if online rivals remain cheaper.

Evaluation prompts

Use these questions to turn a Porter table into analysis:

| Force | Evaluation question | |---|---| | Supplier power | Can the business reduce dependence or negotiate better terms? | | Buyer power | Can the business differentiate enough to reduce price pressure? | | Rivalry | Is the business competing on price, quality, service, convenience or brand? | | Substitution | What customer need is the substitute satisfying better? | | Entry | What barriers can protect the business from new competitors? |

Connecting to business functions

Porter's five forces often leads to functional strategies. Supplier power may require operations to diversify suppliers. Buyer power may require marketing to improve loyalty. Rivalry may require finance to review margins and pricing. Substitution may require product innovation. Threat of entry may require brand investment, patents, exclusive partnerships or economies of scale.
