Porter five forces analysis is a framework to analyze level of competition within an industry and business strategy development. It draws upon industrial organization (IO) economics to derive five forces that determine the competitive intensity and therefore attractiveness of an Industry. Attractiveness in this context refers to the overall industry profitability. An “unattractive” industry is one in which the combination of these five forces acts to drive down overall profitability. A very unattractive industry would be one approaching “pure competition”, in which available profits for all firms are driven to normal profit. This analysis is associated with its principal innovator Michael E. Porter of Harvard University.
Porter referred to these forces as the micro environment, to contrast it with the more general term macro environment. They consist of those forces close to a company that affect its ability to serve its customers and make a profit. A change in any of the forces normally requires a business unit to re-assess the marketplace given the overall change in industry information. The overall industry attractiveness does not imply that every firm in the industry will return the same profitability. Firms are able to apply their core competencies, business model or network to achieve a profit above the industry average. A clear example of this is the airline industry. As an industry, profitability is low and yet individual companies, by applying unique business models, have been able to make a return in excess of the industry average.
Porter’s five forces include – three forces from ‘horizontal’ competition: the threat of substitute products or services, the threat of established rivals, and the threat of new entrants; and two forces from ‘vertical’ competition: the bargaining power of suppliers and the bargaining power of customers.
Porter developed his Five Forces analysis in reaction to the then-popular SWOT analysis, which he found unrigorous and ad hoc. Porter’s five forces is based on the Structure-Conduct-Performance paradigm in industrial organizational economics. It has been applied to a diverse range of problems, from helping businesses become more profitable to helping governments stabilize industries. Other Porter strategic frameworks include the value chain and the generic strategies.
Five Forces
Threat of new entrant
Profitable markets that yield high returns will attract new firms. This results in many new entrants, which eventually will decrease profitability for all firms in the industry. Unless the entry of new firms can be blocked by incumbents (which in business refers to the largest company in a certain industry, for instance, in telecommunications, the traditional phone company, typically called the “incumbent operator”), the abnormal profit rate will trend towards zero (perfect competition).
The following factors can have an effect on how much of a threat new entrants may pose:
- The existence of barriers to entry (patents, rights, etc.). The most attractive segment is one in which entry barriers are high and exit barriers are low. Few new firms can enter and non-performing firms can exit easily.
- Government policy
- Capital requirements
- Absolute cost
- Cost disadvantages independent of size
- Economies of scale
- Economies of product differences
- Product differentiation
- Brand equity
- Switching costs or sunk costs
- Expected retaliation
- Access to distribution
- Customer loyalty to established brands
- Industry profitability (the more profitable the industry the more attractive it will be to new competitors)
Threat of substitute products or services
The existence of products outside of the realm of the common product boundaries increases the propensity of customers to switch to alternatives. For example, tap water might be considered a substitute for Coke, whereas Pepsi is a competitor’s similar product. Increased marketing for drinking tap water might “shrink the pie” for both Coke and Pepsi, whereas increased Pepsi advertising would likely “grow the pie” (increase consumption of all soft drinks), albeit while giving Pepsi a larger slice at Coke’s expense. Another example is the substitute of traditional phone with a smart phone. Potential factors:
- Buyer propensity to substitute
- Relative price performance of substitute
- Buyer switching costs
- Perceived level of product differentiation
- Number of substitute products available in the market
- Ease of substitution
- Substandard product
- Quality depreciation
- Availability of close substitute
Bargaining power of customers (buyers)
The bargaining power of customers is also described as the market of outputs: the ability of customers to put the firm under pressure, which also affects the customer’s sensitivity to price changes. Firms can take measures to reduce buyer power, such as implementing a loyalty program. The buyer power is high if the buyer has many alternatives. The buyer power is low if they act independently e.g. If a large number of customers will act with each other and ask to make prices low the company will have no other choice because of large number of customers pressure.
Potential factors:
- Buyer concentration to firm concentration ratio
- Degree of dependency upon existing channels of distribution
- Bargaining leverage, particularly in industries with high fixed costs
- Buyer switching costs relative to firm switching costs
- Buyer information availability
- Force down prices
- Availability of existing substitute products
- Buyer price sensitivity
- Differential advantage (uniqueness) of industry products
- RFM (customer value) Analysis
- The total amount of trading
Bargaining power of suppliers
The bargaining power of suppliers is also described as the market of inputs. Suppliers of raw materials, components, labor, and services (such as expertise) to the firm can be a source of power over the firm when there are few substitutes. If you are making biscuits and there is only one person who sells flour, you have no alternative but to buy it from them. Suppliers may refuse to work with the firm or charge excessively high prices for unique resources.
Potential factors are:
- Supplier switching costs relative to firm switching costs
- Degree of differentiation of inputs
- Impact of inputs on cost or differentiation
- Presence of substitute inputs
- Strength of distribution channel
- Supplier concentration to firm concentration ratio
- Employee solidarity (e.g. labor unions)
- Supplier competition: the ability to forward vertically integrate and cut out the buyer.
Intensity of competitive rivalry
For most industries the intensity of competitive rivalry is the major determinant of the competitiveness of the industry.
Potential factors:
- Sustainable competitive advantage through innovation
- Competition between online and offline companies
- Level of advertising expense
- Powerful competitive strategy
- Firm concentration ratio
- Degree of transparency
