Porter’s Five Forces Framework: How It Works and Where It Is Used

What Porter’s Five Forces Include

Industry Rivalry

This describes how intense competition is among existing companies. The level of rivalry is influenced by:

• the number of market players and their relative size;
  
  
• the degree of similarity between products and services, and noticeable differences between offers;
  
  
• price competition and transparency in price formation;
  
  
• market growth dynamics and the emergence of new technologies and services.

A company’s fixed costs are also taken into account: rent, equipment, salaries, and loan servicing. When costs are high, companies may take orders even with minimal profit if this prevents downtime.

Leaving the market, in turn, requires selling off assets, laying off employees, fulfilling remaining contractual obligations, and sometimes paying penalties. Because of this, some players remain in the industry despite low profitability, continuing to compete, lower prices, and retain customers.

Threat of Potential Competitors

This reflects how easy it is for new companies to enter the industry and start competing with existing players. Several areas are assessed:

• the amount of initial investment: launch, equipment, premises, and hiring employees;
  
  
• requirements for technology and infrastructure, without which the product or service cannot operate;
  
  
• regulatory barriers: laws, licenses, and patents that restrict market entry or make it long and expensive;
  
  
• availability of sales channels: whether distributors, marketplaces, and partner platforms are ready to work with a new player;
  
  
• brand stability in the niche and audience openness to alternatives;
  
  
• advantages of existing large companies: favorable purchasing terms, reduced costs, and priority in logistics.

Threat of Substitutes

Substitutes are products and services that meet the same user need in a different way. Common examples include taxis and car sharing, printed newspapers and news websites, cinemas and streaming services.

During the assessment, the cost of the alternative, its quality, ease of use, and the pace of growth in popularity are compared. If a substitute offers better terms or a more comfortable user experience, part of the audience switches to it. This gradually changes the structure of demand and affects the development of the entire industry.

Bargaining Power of Suppliers

Here, the dependence of the business on those who provide raw materials, components, equipment, or services is assessed. In essence, this is about the degree of choice and the risk of becoming tied to a limited group of suppliers.

The following factors are taken into account:

• the number of suppliers in the market and the comparability of their offers;
  
  
• the uniqueness of a resource or technology that may give the supplier stronger negotiating terms;
  
  
• the share of purchases in the product’s cost structure and the likelihood of price increases;
  
  
• the risk of supply disruptions related to logistics, geography, or political restrictions;
  
  
• the possibility of vertical integration: whether the supplier can enter retail or create its own brand and begin competing with current customers.

Bargaining Power of Buyers

In Porter’s Five Forces model, this indicator reflects how much customers can influence prices, product range, and the company’s operating terms. The analysis includes several parameters:

• audience sensitivity to price: when customers react strongly to price increases, pricing flexibility is reduced;
  
  
• ease of switching to another brand when offers are comparable;
  
  
• availability of information about products and companies, and transparency of comparison by features and price;
  
  
• order size: a major customer that accounts for a significant share of revenue may demand special terms;
  
  
• the risk of the customer becoming independent: for example, a supermarket chain launches its own private label and reduces purchases from suppliers.

How to Apply Porter’s Method in Practice

Step 1. Describe the Industry

At the first stage, the context in which the business will operate is assessed. This forms a basic understanding of the market and the conditions that affect all its participants.

The analysis includes:

• a list of companies in the industry, their size, specialization, and positions;
  
  
• market growth rates and trends that shape demand;
  
  
• audience structure: customer segments, consumption volumes, and buyer behavior;
  
  
• the level of technological development and restrictions related to regulation, standards, logistics, and infrastructure.

Step 2. Analyze Each Force Separately

After describing the market, you can move on to a detailed analysis of Porter’s Five Forces. The task here is to determine which factors strengthen or weaken the influence of each force and how this affects business profitability.

The analysis should be based on verified data: industry reports, official statistics, public company results, thematic studies, and interviews with customers and partners. The more accurate the inputs, the lower the subjectivity and the more realistic the assessment of each force.

Step 3. Determine the Level of Influence

When the facts for each force have been collected, they are converted into a clear scale that reflects the degree of influence on profit and business stability. A simple gradation is usually used: low, medium, or high influence.

A descriptive example of Porter’s Five Forces may look like this:

• assessment of competition: “there are many players, products are similar, dumping is used → influence is high”;
  
  
• assessment of the threat of new entrants: “the entry threshold is high, significant investment, licenses, and complex infrastructure are required → influence is low”;
  
  
• assessment of suppliers: “the market is concentrated around several large companies, raw materials are rare and expensive → influence is closer to high”;
  
  
• assessment of buyers: “high price sensitivity, easy switching between brands → influence is high”;
  
  
• assessment of substitutes: “there are few suitable alternatives, they are more expensive and less convenient → influence is low.”

It is important to consider industry specifics: in some industries, tough supplier conditions may be considered normal, while in others they may be seen as an anomaly. Therefore, conclusions are always tied to the practice of a specific market. As a result, each force gets a short but informative description: how much it affects the business and where significant risks exist.

Step 4. Compare the Forces and Build the Overall Picture

Finally, after assessing each force separately, they are considered together to see which mechanisms shape the overall economics of the market. At this stage:

• the forces that create the main pressure, risk level, and influence on margin are identified;
  
  
• the most vulnerable areas are recorded;
  
  
• growth areas and potential points for strengthening the company’s position are defined;
  
  
• factors that may limit development in the long term are noted.

On this basis, a full business analysis can be carried out and strategy can be discussed: whether to enter the market, which segments to develop, how to work with suppliers and customers, which product characteristics to strengthen, and what price positioning to choose.

How to Interpret the Results in Porter’s Five Forces Matrix

The model does not divide markets into “good” and “bad.” Its purpose is to show their structure: what shapes company stability and what risks may arise.

Below is the general influence of each force on a business without reference to a specific industry.

Conclusion

Porter’s Five Forces are a way to assess an industry through the factors that may change the balance in the market over time. They make strategic discussion more specific: hypotheses, calculations, and new scenarios appear.

After assessing and mapping the forces, companies discuss which actions will reduce pressure, what can strengthen the company’s advantages, and which market signals should be tracked first. In this way, Porter’s method turns from an academic framework into a full working tool.
