Porter's fives forces model

Porter's fives forces model

The Porter's Five Forces tool is a simple but powerful tool for understanding where power lies in a business situation. This is useful, because it helps you understand both the strength of your current competitive position, and the strength of a position you're considering moving into.

With a clear understanding of where power lies, you can take fair advantage of a situation of strength, improve a situation of weakness, and avoid taking wrong steps. This makes it an important part of your planning toolkit.

Conventionally, the tool is used to identify whether new products, services or businesses have the potential to be profitable. However it can be very illuminating when used to understand the balance of power in other situations.

Porter's fives forces model is an excellent model to use to analyse a particular environment of an industry. So for example, if we were entering the PC industry, we would use Porter's model to help us find out about:

The above five main factors are key factors that influence industry performance, hence it is common sense and practical to find out about these factors before you enter the industry. Lets look at them below.

Threat of New Entrants

New entrants to an industry can raise the level of competition, thereby reducing its attractiveness. The threat of new entrants largely depends on the barriers to entry. High entry barriers exist in some industries (e.g. shipbuilding) whereas other industries are very easy to enter (e.g. estate agency, restaurants). Key barriers to entry include

- Economies of scale
- Capital / investment requirements
- Customer switching costs
- Access to industry distribution channels
- The likelihood of retaliation from existing industry players.

Threat of Substitutes

The presence of substitute products can lower industry attractiveness and profitability because they limit price levels. The threat of substitute products depends on:

- Buyers' willingness to substitute
- The relative price and performance of substitutes
- The costs of switching to substitutes

Bargaining Power of Suppliers

Suppliers are the businesses that supply materials & other products into the industry.

The cost of items bought from suppliers (e.g. raw materials, components) can have a significant impact on a company's profitability. If suppliers have high bargaining power over a company, then in theory the company's industry is less attractive. The bargaining power of suppliers will be high when:

- There are many buyers and few dominant suppliers
- There are undifferentiated, highly valued products
- Suppliers threaten to integrate forward into the industry (e.g. brand manufacturers threatening to set up their own retail outlets)
- Buyers do not threaten to integrate backwards into supply
- The industry is not a key customer group to the suppliers

Bargaining Power of Buyers

Buyers are the people / organisations who create demand in an industry

The bargaining power of buyers is greater when

- There are few dominant buyers and many sellers in the industry
- Products are standardised
- Buyers threaten to integrate backward into the industry
- Suppliers do not threaten to integrate forward into the buyer's industry
- The industry is not a key supplying group for buyers

Intensity of Rivalry

The intensity of rivalry between competitors in an industry will depend on:

- The structure of competition - for example, rivalry is more intense where there are many small or equally sized competitors; rivalry is less when an industry has a clear market leader

- The structure of industry costs - for example, industries with high fixed costs encourage competitors to fill unused capacity by price cutting

- Degree of differentiation - industries where products are commodities (e.g. steel, coal) have greater rivalry; industries where competitors can differentiate their products have less rivalry

- Switching costs - rivalry is reduced where buyers have high switching costs - i.e. there is a significant cost associated with the decision to buy a product from an alternative supplier

- Strategic objectives - when competitors are pursuing aggressive growth strategies, rivalry is more intense. Where competitors are "milking" profits in a mature industry, the degree of rivalry is less

- Exit barriers - when barriers to leaving an industry are high (e.g. the cost of closing down factories) - then competitors tend to exhibit greater rivalry.

For example:

• if firms merge together this can reduce the degree of rivalry . This has happened a great deal in industries such as automobiles, pharmaceuticals and banking where firms have joined together to remove competitors
• if firms buy up distributors (this is called forward vertical integration) they can gain more control over buyers
• if firms differentiate their product perhaps by trying to generate some form of Unique Selling Proposition (USP) that makes it stand out from the competition. This lies at the heart of many marketing and brand building activities. Coca Cola, for example, has fought hard to promote itself as "the real thing"; everything else is just imitation!
• if they react aggressively to a firm that enters its market this may deter potential entrants in the future

The five forces will change over time as market conditions alter. For example, more information is available nowadays to enable customers to compare offerings and prices; this gives buyers more power. The opening up of world markets (for example through the efforts of the World Trade Organisation to reduce protectionist measures that limit trade and the expansion of the European Union enabling free trade between more countries) has led to much more rivalry in markets in recent years. In North America, for example, the sales of Japanese firms such as Toyota have gradually been reducing the market share of American producers such as General Motors as consumers have more choice. Meanwhile, the success of the internet has made it easier for producers to enter many markets such as finance, book retailing and clothes retailing; the ability to start selling online has reduced a major barrier to entry which was the investment required to set up a network of shops. As ever the business world is not static and the conditions in any industry will always be changing. As this happens the various elements of the five forces are always shifting requiring established firms and potential entrants to review their strategies.
