Introduction to Porter's five forces

Porter's Five Forces is a strategic framework designed to analyze the competitive forces shaping an industry. Developed by Michael E. Porter, the model helps businesses assess both the intensity of competition and the overall attractiveness of a market.

When working with strategy and execution, you must understand your company’s competitive situation and position in order to choose the optimal strategy. This requires an analysis of the competitive conditions in the industry, including the company’s strength relative to its competitors, and its dependency on suppliers, customers, and others.The purpose of an industry analysis is to assess:

• Trends in the industry – where the development is heading
• How attractive the industry is
• The earning potential
• The intensity of competition

A widely recognized model for structuring and focusing an industry analysis is Michael Porter’s Five Forces model, described in his book Competitive Strategy (1980).

What are Porter’s Five Forces?

Porter’s Five Forces is a framework for analyzing the competitive dynamics within an industry.

According to Michael Porter, the level of competition and profitability in an industry is shaped by five competitive forces.

The core principle is: the stronger the competition, the lower the potential for profit.

The five competitive forces – Porter’s Five Forces – are:

1. Rivalry among existing competitors
2. Bargaining power of customers
3. Bargaining power of suppliers
4. Threat of new entrants
5. Threat of substitute products or services

Each of these forces can either positively or negatively affect the intensity of competition, thereby making the industry as a whole more or less profitable.

By analyzing each force individually, you can gain a clear picture of the competitive intensity in the industry and, consequently, assess how attractive the industry is.

Below are examples of what each of the five forces includes:

The five forces

1. Threat of new entrants:
   This force examines how easy or difficult it is for new competitors to enter the market. High entry barriers – such as substantial capital requirements, stringent regulations, or strong brand loyalty – can limit new competition.
2. Bargaining power of suppliers:
   This force looks at the power suppliers have over an industry. When there are few suppliers or when they offer unique products or services, they can exert significant influence on pricing and quality.
3. Bargaining power of buyers:
   This examines the influence that customers have on pricing and product quality. When buyers have many alternatives or low switching costs, their negotiating power increases.
4. Threat of substitute products or services:
   This force evaluates the likelihood that customers will switch to alternative products or services. A high threat of substitutes pressures companies to innovate and adjust their pricing strategies.

Industry rivalry:
This force looks at the intensity of competition among existing firms in the industry. High rivalry often leads to price wars, increased marketing efforts, and continuous innovation, all of which can reduce profit margins.

Applying the model

By analyzing these five forces, businesses can identify both opportunities and threats within their industry. This insight can guide strategic decisions such as:

• Developing strategies to deter new entrants, for example by building strong brand loyalty or increasing operational efficiencies.
• Negotiating better terms with suppliers and buyers by understanding their relative power in the market.
• Innovating to differentiate products and reduce the threat of substitutes.
• Managing competitive rivalry through strategic pricing, marketing, and continuous improvement.

Conclusion

Porter's Five Forces provides a comprehensive framework for understanding the competitive dynamics of any industry. By systematically analyzing each force, companies can develop more effective strategies to enhance their competitive position and drive long-term success.
