Five Forces analysis is a framework for analyzing the five competitive forces that determine an industry’s profitability, in order to clarify a company’s competitive advantages and its future strategy. This analysis makes the structure of the entire industry and the “threats” surrounding the company visible. In this article, we explain what the Five Forces model is in plain terms \u2014 from its basic ideas to concrete usage, and even how it can be combined with other related frameworks \u2014 with practical information you can use.<\/p>\n\n\n

Overview of Five Forces Analysis<\/h2>\n\n\n\n
\"A<\/figure>\n\n\n\n

The Five Forces model is a framework in management studies and marketing proposed by the American management scholar Michael E. Porter.
It is used to understand an industry’s profitability and the intensity of competition within it. By analyzing five key “threats,” it evaluates the attractiveness of an industry and the profitability of a company within it.<\/p>\n\n\n\n

The originator of Five Forces analysis and its basic idea<\/h3>\n\n\n\n

Five Forces analysis was proposed by Michael E. Porter, a professor at Harvard Business School.<\/p>\n\n\n\n

Introduced in his book Competitive Strategy<\/em>, this framework is based on the fundamental idea that an industry’s profitability is determined by five competitive forces: “rivalry among existing competitors,” “threat of new entrants,” “threat of substitutes,” “bargaining power of buyers (customers),” and “bargaining power of suppliers.”<\/p>\n\n\n\n

By analyzing these forces, a company can objectively grasp the competitive environment it faces. It is also useful for strategic decision-making.<\/p>\n\n\n

The five threats that make up Five Forces analysis<\/h2>\n\n\n\n
\"People<\/figure>\n\n\n\n

Five Forces analysis evaluates the five “threats” that determine an industry’s profitability.<\/p>\n\n\n\n

If these threats are strong, earning profits in the industry is judged to be difficult; if they are weak, there is an opportunity to improve profitability.<\/p>\n\n\n\n

Let’s look at each threat in detail.<\/p>\n\n\n\n

\"\"
Figure 1: Five Forces analysis diagram<\/figcaption><\/figure>\n\n\n\n

[Threat 1] Rivalry among existing competitors<\/h3>\n\n\n\n

Rivalry among existing competitors refers to the intensity of competition among existing firms in the industry your company belongs to.<\/p>\n\n\n\n

A large number of competitors, the presence of many large firms, or difficulty in differentiating products and services (which easily leads to price competition) all act as major threats that lower profitability.<\/p>\n\n\n\n

It is important for a company to objectively grasp its own position by analyzing competitors’ financial strength, technical capability, sales capability, brand power, market share, and so on.
In a highly competitive industry, even just maintaining market share involves significant costs. To secure profit in such an environment, a more differentiated strategy is required.<\/p>\n\n\n\n

[Threat 2] Threat of new entrants<\/h3>\n\n\n\n

The threat of new entrants refers to the possibility of new firms entering the industry your company belongs to, and the impact this would have on existing companies.<\/p>\n\n\n\n

In industries where the barrier to entry is low, an increase in new entrants intensifies competition, and price competition or loss of market share threatens to reduce the profitability of existing firms.<\/p>\n\n\n\n

For example, industries with low initial investment requirements and no need for special technology or licenses tend to be easy to enter.<\/p>\n\n\n\n

Conversely, industries that require government regulation or large capital investment have high entry barriers, so the threat of new entrants is small.<\/p>\n\n\n\n

It is important to analyze this threat by also considering market size, the brand power of incumbents, and the technical level of potential entrants.<\/p>\n\n\n\n

[Threat 3] Threat of substitutes<\/h3>\n\n\n\n

The threat of substitutes refers to the possibility that products or services that meet customers’ needs in a different way from your own will appear on the market.<\/p>\n\n\n\n

For example, just as the rise of smartphones significantly reduced demand for landline phones, digital cameras, and portable music players, technological innovation can produce substitutes that come from outside your traditional competitors.<\/p>\n\n\n\n

As substitutes improve in performance and decrease in price, the risk of customers switching to them grows.<\/p>\n\n\n\n

Because the emergence of such substitutes can fundamentally change the profit structure of incumbents, it is important to constantly watch market changes, identify potential substitutes early, and develop strategies to deal with them.<\/p>\n\n\n\n

[Threat 4] Bargaining power of buyers (customers)<\/h3>\n\n\n\n

The bargaining power of buyers refers to the degree of influence customers (buyers) have over your company in terms of price, quality, and conditions of the products or services you provide.<\/p>\n\n\n\n

When the number of buyers is small but their purchase volume is large, buyers gain a strong position in price negotiation and can easily demand discounts \u2014 a clear threat.<\/p>\n\n\n\n

In addition, when there is no clear differentiation between your product and competitors’ products, or when buyers’ switching costs (the cost or hassle of moving to other products or services) are low, buyers’ bargaining power increases.<\/p>\n\n\n\n

When buyer bargaining power is high, firms are forced to lower prices to maintain profitability, which puts pressure on profit margins. It is therefore critical to accurately understand customer needs and continue to provide value.<\/p>\n\n\n\n

[Threat 5] Bargaining power of suppliers<\/h3>\n\n\n\n

Bargaining power of suppliers refers to the degree of influence that suppliers (those who provide raw materials, parts, services, etc.) have over your company in terms of price, quality, and supply conditions.<\/p>\n\n\n\n

When suppliers are few in number and your company depends on a specific supplier, or when a supplier provides scarce raw materials or parts with advanced technology, suppliers’ bargaining power increases.<\/p>\n\n\n\n

As a result, suppliers may raise prices or restrict supply, threatening to drive up your production costs and worsen your profitability.<\/p>\n\n\n\n

To weaken supplier bargaining power, you should consider building relationships with multiple suppliers, securing substitutable procurement sources, or even bringing production in-house.<\/p>\n\n\n\n
