Porter's Five Forces is a framework for analyzing the competitive environment of an industry. It was developed by Harvard Business School professor Michael E. Porter in 1979 and has since become an important tool for managers.
Porter's Five Forces framework The five forces are:
Threat of new entrants: This is the threat of new companies entering the industry. New entrants can bring new capacity, new technologies, and new ideas, which can put downward pressure on prices and profits for existing companies. | Bargaining power of suppliers: This is the power that suppliers have to influence the prices and terms of trade. Suppliers can have high bargaining power if there are a few large suppliers, if the products they supply are unique or difficult to substitute, or if the cost of switching to a different supplier is high. | Bargaining power of buyers: This is the power that buyers have to influence the prices and terms of trade. Buyers can have high bargaining power if there are a few large buyers, if the products they buy are standardized and easy to substitute, or if the cost of switching to a different supplier is low. | Threat of substitutes: This is the threat of existing products or services being replaced by new ones. The threat of substitutes is high if there are close substitutes available, if the cost of switching to a substitute is low, or if the performance of the substitute is superior. | Competitive rivalry: This is the intensity of competition among existing companies in the industry. Competitive rivalry is high if there are many competitors, if the products are differentiated, or if the exit barriers from the industry are high. |
There is an additional force considered
"Porter’s Sixth Force Definition
Complementors, Porter’s sixth force, are companies or entities that sell or offer goods or services that are compatible with, or complementary to, the goods or services produced and sold in a given industry. Complementary goods offer more value to the consumer together than apart. When one product or service complements another there exists a condition called complementarity; a sort of commercial symbiosis. Complementors are often considered the sixth force of Porter’s industry analysis framework. The presence of Porter’s complementors can influence the competitive structure of an industry." strategiccfo.com
How to use Porter's Five Forces
To use Porter's Five Forces, businesses should assess each of the five forces and identify the strengths and weaknesses of their business in relation to each force. This information can then be used to develop strategies to mitigate the negative impacts of the forces and capitalize on the positive impacts.
For example, if a business faces a high threat of new entrants, it may develop strategies such as product differentiation, brand building, or high entry barriers. If a business faces a high bargaining power of buyers, it may develop strategies such as product differentiation, supplier integration, or customer switching costs. Example Here is an example of how a business might use Porter's Five Forces to analyze its competitive environment: Industry: Smartphone industry
Threat of new entrants: High
| Bargaining power of suppliers: Medium
| Bargaining power of buyers: Medium
| Threat of substitutes: High
| Competitive rivalry: High
|
Strategies Based on this assessment, the smartphone industry business could develop the following strategies:
To mitigate the threat of new entrants, the business could focus on product differentiation, brand building, and high entry barriers.
To mitigate the bargaining power of suppliers, the business could develop supplier relationships, integrate with suppliers, or develop alternative sources of supply.
To mitigate the bargaining power of buyers, the business could focus on product differentiation, customer service, and switching costs.
To mitigate the threat of substitutes, the business could focus on product innovation, product bundling, and customer switching costs.
To compete effectively with other smartphone manufacturers, the business could focus on product differentiation, brand building, and cost control.
Industry: Airline industry
Threat of new entrants: Medium
| Bargaining power of suppliers: Medium
| Bargaining power of buyers: High
| Threat of substitutes: High
| Competitive rivalry: High
|
Strategies
Based on this assessment, airlines could develop the following strategies:
To mitigate the threat of new entrants, airlines could focus on brand building, customer loyalty programs, and cost control.
To mitigate the bargaining power of suppliers, airlines could develop relationships with suppliers, negotiate long-term contracts, and hedge fuel costs.
To mitigate the bargaining power of buyers, airlines could focus on product differentiation, customer service, and loyalty programs.
To mitigate the threat of substitutes, airlines could offer a variety of fare options, develop new routes, and partner with other transportation providers.
To compete effectively with other airlines, airlines could focus on product differentiation, cost control, and network efficiency.
